Some of yuo may remember that i've been having some difficulties with my stilo over the past 6months...I will catalogue them below and then ask for advice.

Some time in May last year, she started suffering from idle problems and really intermittent problems with oil pressure alerts..

then the white smoke started, and she quite frankly blew up.

I had a cash-flow problem and took at couple of month to get her collected and repaired... this turned out to be coil packs, head gasket and timing belt.

all the above got sorted and she was running again but with noisy tappets.
at least she's back on the road.

anyway, suddenly one cold evening, i ran away from the lights near my house and the timing tensioner had slipped and in turn the timing belt went.
this in turn knackered some exhaust valves.

I've now had that all fixed, and it was then stalling every time I dipped the clutch..

so next i've replaced the inlet control valve, and result, it's not stalling every time... just some of the time although idling is rough as a butcher's block.

so, now i get intermittent warnings of oil pressure being low on start up, and she stalls randomly when i drop the clutch and it's idling really poorly.

HELP. Please please tell me what I can do to get it right....I am, for lack of a better word...sick to the back teeth.:bang:

Does the ide bounce about 3 or 4 times then cut out.. or does it just drop off and cut out straight away??

usually it just drops off, but on occasions it bounces and then stalls...

then there are times the revs drop off entirely and then pick themselves back up again instantly.
 
Bit of a stab in the dark, but have a go at cleaning the inlet butterfly/throttle body... i had similar problems..... as it would idle it would float between 600 and 850rpm and never steady... cleaned it and its been rock steady....

if i used to leave the clutch too late it used to bounce and stall but doesnt anymore...

the guide on it

https://www.fiatforum.com/stilo-guides/83260-cleaning-your-inlet-control-valve.html

But me being a dumbass and not entirely reading the thread see you have already replace the throttle body:bang::bang:

Isnt there a throttle reset by turning the ignition on and pressin the throttle 5 times or something??? sure ive heard that somewhere... I think either Decks or T14.. mentioned it

Hopefully they should know

well, i hope they hurry up, i'm meant to be going to york tomorrow and would like it runnin a little better.
 
Well your engine's certainly had a tough time.

Yes, clean very carefully the inlet valve in the throttle body especially in the areas shown in my guide in the Stilo Guides and reset the ECU by disconnecting the battery for an hour or by clearing any fault codes if you have the gear as that will reset the ecu as well. Then see how you go as the ecu relearns the best settings again

I take it this is a 1.6 or 1.8 and you don't know of any fault codes cropping up now?

there are no fault codes present, well, there weren't any...
it's had a brand new inlet control valve nice and sparkly clean.
it's had it's ecu reset and its still being a bitch.

it's a 1.6 as

oh.
dear.

no thanks, I might sell it, but if I do, I'd be moving away from FIAT I'm afraid.

If I had that many problems from mine it would have been long gone before I sold it :p thing is it was a 5dr :slayer:and they are definitely more reliable :D
 
ok, so i fired her up and got a low oil pressure warning.

she's making an electric noise cos it's cold, so i'm gonna go give her a run in to see if it'll run ok...what should I expect?

Our 5dr was far more unreliable - hence the reason it's going on Saturday!

a tow home maybe?

ahha... well, she's running still... rough idling..
not too cracking but she didn't stall.
dragging to the left a little, but I'm not sure what that's about.

I'm sick of this. I've just lost all faith in her.
 
You could try a manual throttle relearn procedure, but I doubt it'll do anything:

1. Switch the Ignition on and leave it on for 60 seconds without starting the engine or depressing any pedals - this gives the throttle body enough time to realise it's in self-learn, open the inlet control valve and record data such as it's maximum open degree, resistance to opening e.t.c.
2. Switch the Ignition off completely for 10 seconds - this then writes the newly saved data to the EEPROM memory of the throttle body.
3. Switch the engine on, and run for a few miles.

See if that helps? Again, no promises. Are you sure your oil circulation system is ok? (i.e. oil pump ok, no blocked filter?)
 
Your engine's taking such a bruising it's difficult to know where to start.
The throttle and ecu should hold tickover rock steady at 700rpm.

Did it run right after that last episode of work done on it?
Are the plugs good?
Does it sound rich on tickover? blub blub at the exhaust.
Is it hunting? ie sound weak and "splashy" at the exhaust?
Does it pick up acceleration ok?
Is it misfiring at all?
What's this low oil pressure all about? How long has it been doing that and when does it do this?
Does it have poor idle when cold and when hot?

I'm concerned about the oil now. I would rather that wasn't something else that was going wrong.

I'll try that throttle thing tomorrow morning before work.

with respect to the oil, how willl I know if the circulation system wasn't working? The filter is new and it's all been flushed, but I don't really know enough about the rest to fix it.
