You could cover the MAP sensor with neat crude oil (if you could afford some) and it wouldn't make any difference. A 1.6 engine will run quite happily with no MAP sensor connected at all. So tell us more, what makes you believe it is the MAP sensor? Are you getting MAP fault codes? P0105 maybe?

When you say it broke down what happens? Does it not start? Does it stall? Does it not tickover? Does it have a sulk? Is it just fed up with life? Or is it suffering from low self esteem?

Tell us more. The more detail you give the better answers you get

Once i was let down by mine MAP, and it was near the period that i've changed my throttle body and some coils. Finally found out that responsible were 3 out of 6 cable lines on the throttle body's connector.

Why don't give a try to check your wiring between throttle body and ECU...

have a look at throttle bodycleanout in the stilo guides section.. ( up top ) this threw my engine management into thinking it was a faulty map sensor.. it was tripping engine fault every 2-3 days.. hows the idle?? does it float or is it rock steady, i clean the throttle body out atn its not played up since.. i possibly think this is also overcome by the update from fiat to.. but give it a try... i did a thread about it..
 
you got an K&N type filter on by any chance or are you still running the paper panel filter??



i have the same problem and i have a K&N filter on?

is this an airflow issue? i have had the filter on for about a year and no issues up until this morning,
PLEASE HELP!!
 
Never had similar problem caused by my K&N type filter. Nor the guys on StiloClub.gr.
Try to check wiring, faulty MAP sensor and/or throttle body.

Does the engine management light goes off after few restarts?
 
nope.
I started up this morning, engine management light came on with warning then engine died.
repeated a few times, same thing happened.

if i sit with the revs up at around 2000rpm the it's ok but if you drop below that it struggles, tried driving with the car in 2nd gear it moves under its own throttle but as soon as you dip the clutch the engine dies again. i didn't have enough time before work this morning to run it to see if the same happens on a hot start, will try this afternoon.

NIGHTMARE!!

having a look thru the forum i can see a few things that i will try, checking/cleaning the inlet manifold for gunge, check connections on and around throttle body.

Fingers crossed its something simple.
 
On top of my head:
If no message from the car (no beeps), then most likely is something like dirt in the inlet. If in full throttle you get sit backs then maybe is something with your fuel system.

If you getting a message, what does it says?

Check and the sparks just in case... When did you had your last service?

i serviced it in January, cleaned inlet value and check spark plugs. engine now runs fine, idle's fine and no loss of power hot or cold.
however, the engine management light remains in the dash, i have been told by a local auto electrics shop that once a fault registers it is logged until it is clearer by a diognostics machine, evern if you have sorted the fault yourself?

Is this the case, and is there a way of clearing it myself?

cheers

Almost exact same problem... I was constantly driving having the revs up to 2000~2100 rpm on idle to avoid ECU Safe Mode...:mad: Not always succesfull of course. If you have throttle body problem, the management light will go off after a few restarts.

If your MAP is faulty, the management ligh will stay on. Even if you replace the damn part. You 'll need to reset it. Can't be done by yourshelf. Needs some kind of expert s/w (i did it on my electricians shop - NOT Examiner). Or a visit to your local bucher...eeerr, FIAT dealership.:bang:
 
A standard fault code reader will erase the code so no problems there. A 1.6 will ignore the MAP sensor if it detects any problems there and relies on pretty good guesswork from it's in built MAP chart. Your mpg won't be at it's best by a long way though

Erasing the code will also reset the ECU for it to relearn the best settings again so it's important to find the fault and erase the code

Things have settled down again, and after a complete strip down, cleaning all electrical points, spark plugs, throttle body, seems to have helped the situation. the warning light is still on in the dash but thats due to be reset by garage soon (at the same time i will get my service warning put back 12K!).

There is definately no loss of power in the car as it stands now, and just seems to be yet another case of dodgey italian electrics. i like my fiat, but down like the way they build it!!

Case closed. cheers guys and dolls!
 
Please help!!! And sorry it's a long message.

I Bought 3rd hand 2002 5 door 1.6 Stilo in May 2008.
Drove OK to start with, then started to feel:
a. pulling to left
b. a diesel - type chugging when in neutral waiting at traffic lights
c. stalling at round-a-bouts, and lights (no comments about my driving please)
d. lack of power accelerating, but surging when changed into third gear upwards
e. 1st gear feeling like it's going to stall (and then somtimes stalling)
f. 2nd gear running way/pulling forward

All this culminated in my car cutting out twice when driving off from parked (I only got 50 yards down the road) - this was during the last week of June 2008 - and the orange engine light came on, display flashed "engine failure" message, and a very scary ping, ping, ping.

RAC man plugged his computer in and said it was MAP sensor fault & cleared the error message.

Took Stilo to garage (not main dealer) for service - as 'Service Due' message had also flashed up. Told garage about MAP sensor fault. When I collected car they said they checked the Map Sensor and found arm, wiring & plug connector OK, though the pin that clips the plug in place had come off and they'd secured it with cable ties because otherwise it was OK. They claimed they had also done the service (i.e. change oil, blah blah). They also noted: Steering Rack Leaking & Gear box Leaking from near side drive shaft. I drove the car home that same day. All seemed OK, though was still unsure about acceleration (the drive home from the garage is 22 miles).

The next morning I set off for work in the car (to go back the 22 miles) and got 1/2 mile before I lost acceleration, the car started pulling and slowing, I stalled at the traffic lights and when I restarted the engine the engine fault light came on again. Took car back home and called the garage. Returned car to garage one week later and their diagnosis (and I quote): "Code read ECU, Misfire no. 2 detected. Check coils and plugs, no faults found. Reassembled, misfire no longer there, suspect vehicle may have an injector fault, refer to main dealer for diagnostics".

Took car to main dealer. Firstly they said I did not need a new steering rack as it is electric not hydraulic and there are no fluids involved; therefore it can't be leaking (so naturally I now wonder just how reliable the first garage actually is!). The dealer also said the Gearbox would need full clean and good run of 200 miles to then see where the leak is originating (I obviously cannot do this at the moment!). Anyhow, they carried out diagnostics, changed the spark plugs and cleaned the throttle body. I collected the car and drove home (only 2 miles this time) and all seemed well. I had my baby back!!!! After 1 day of the car being parked outside the house, I drove the car 2 miles to the exhaust centre (yes, I also needed a new exhaust) and the car stalled at the lights 1.75 miles into the journey. The car had no power pulling away, and that horrible deisel chugg had come back. I pulled into the exhaust centre, booked the car in and was told 5 mins later by the engineer that as he'd pulled it into the inspection bay the engine fault light had come on. (I have not called myself "depressed" on this forum for nothing).

So far I have spent 500 quid on this 'diganostic' and 'repair' fiasco and am no further forward. I seems that all the things mentioned as soluotions on this forum have all been tried between the two garages I've been to.

Please please are there any ideas forthcoming? The car is back with the main dealer and I'm waiting to hear their verdict this time round.

Thanks......:cry:
 
It sounds like the Fiat dealer has done a fair job but you don't mention if the coil-packs have been replaced (just buy one and rotate through all 4 cylinders - I don't mean buy all 4). If fault doesn't clear then move to next cylinder etc.

I'd ask the Fiat dealer to read faults for you (for free I'd hope ;))
 
The dealership verdict....... !!!!!!!!!!!!!!!!!!!

One coil pack looks new, the other three should be replaced.
Also, all 4 injector rails should be replaced.

Having looked on this forum, and other forums, this is the first time injector rails have been mentioned.

I have a terrible feeling that they're are also grasping at straws..... and I cannot afford to pay for their experient (700 quid!!!!!!!).

Any (constructive) thoughts? (I've enough destructive ones of my own right now).

Cheers.:bang:
 
Like I've already said, change all 4 coil packs (you shouldn't trust the one that looks new).

Only one is going to be suspect so I'd only change one at a time (using the one you take out to replace the next etc).

If you can't manage it yourself then get a local competent garage to do it for you.

If it doesn't solve the problem then all you've paid for is one coil pack and you'll need that anyway one day so just store it on the car somewhere for when you do.
