Hi everyone,

i bought a fiat stilo 1.6, 2002 around six months ago. it has done only 35k miles.it was running fine during the summer. i around 40k now.

About 2 months ago.. the morning was wet and cold, i started the car..it started up in the first go itself...put it into gear as i started to move... it began to jerk... and my car shut down... tried agin the same thing.. after a few tries i started it up.. but the engine management light was on. so i went to near by garage and got it diagnosed. They said the MAP sensor was faulty and needed replacement. i did that and it cost me £200. The very next day the same thing happened. i took it to the same garage. they checked it and said they could not find any fault with it.. so they cleared the engine management light and gave the car back. the car was fine for a few weeks...

then the engine management light came on again... this time i took it to a frnds place... he did a diagnostics and found that it was the MAP sensor again.. HE said to leave it alone and cleared the engine management light. the car was fine for a week...

i was away that week end. that was a very cold week end. i started up the car car the following monday it wouldn't start. i got a frnd to jump start it for me... and it ran fine that week.. i tested the battery using a volt meter and it showed 12.5 and 14.5 when running. During the weekend i had a long drive .. the car didn't show any trouble... on Monday i drove to work in the morning... but in the evening.. i started the car..put in gear and as i moved forward the car shutdown.. i started it up again.. and drove off.. as i started to pick up speed... the engine management light came on... and the beeping sound also... i was not getting much power also.. but i got home...

i booked an appointment with fiat...they diagnosed it and is say its the coil in the 2nd cylinder... i am get it changed and its again cost me £230....the car got fixed again. This was 4 weeks ago.

Now today morning the i started up the car it started fine... as i moved on i lost power and the car shut down. when i tried to start again it showed the engine management light and would not stay on....

after a few try... when i started i put my foot on the accelerator.... it worked... i ramped up the rpm a few times.. and dove off to work... and in the evening drove back from work also... the car drives just fine....

i feel its the MAP sensor again... any idea why its keeps on failing..... ??

i have spent a lot of money on this car till now and still is not reliable.

Any one have any advice....?? Any help is appreciated...

Hi, and welcome to FF,
I'm a bit confused.. how many MAP sensors have you fitted 1? , 2 / 3..??

potentially poor wiring rather than the sensor itself..OR you've got a poor battery / earth and it'll start O.K. but ping up errors due to low voltage after the starter has taken a chunk out,

say hi in the Stilo section, they'll know more..,

good luck,
Charlie

Hi Varesecrazy,

Thank you. i replaced the MAP sensor once... when i got the fault first.... but the fault has come up at least 2 more times..

Not sure what to do to stop this from happening....

Did you try this?

I got the P0105 MAP sensor warning a few years ago, I cleared it using an OBD tool, but it just reappeared after a while, I deleted it again and it again reappeared, etc with increasing frequency. I finally had a garage clean the inlet control valve, and the problem disappeared. Never experienced it since, and it's been years.

If they charged you that to change just one coil it's time to change your garage.
