Help!!

[mushed28]

Hey Guys,

I have a problem with my '99' 206 1.4, When its cold & i start it up, it ticks over on idle fine, as I drive off, its ok but afew minutes later the revs goes mad, revs up and down, but not low enough of it to stall, then afew minutes later it gives itself a massive rev and then its fine, I dont know what it could be

Please Help!!!

I dont know what it could be

I'd say it's the motor playing up.

[citronut]

idle stepper motor

i have had success sorting these by removing it blast it out with carb cleaner then give it a shot of duck oil, or maybe a squirt of 3in1 from a spray can,

i found only using carb cleaner was ok for test purposes but it dried the stepper motor out inside, hence the shot squirt of a very light/fine oil,

do not put WD40 anywhere near it or out else for that matter, except the trash can!!!!!!!

Absolutely

I've had this on a 206 1.4 and a good clean and lube of the idle stepper motor and a good clean of the housing did the trick a treat. You may find a load of gum in the housing.

To give best access it's better to remove the whole throttle body - it's easy, just three screws - and then you can work at it on the bench and do a really good job of it.

Afterward it's a good idea to get the car on to PP2000 diagnostics and re-calibrate the stepper motor and perform and engine ECU re-initialisation.

i dont think it has a throttle body as such Jim as it is probable mono point injection,

spoz thats if its petrol in the first place

[CitroJim]

Most by '99 were multi-point with Magnetti Minarelli injection Malcolm - or at lest the ones I've seen....

Good point if it's a diesel OP hasn't actually said...

Not quite Malcolm - it was there originally but I shifted it as it was a question rather than an introduction and left a shadow there.

I will look at cleaning the area around the housing, Thanks Guys

[mushed28]

Hey Guys, I tired cleaning the motor, and it kinda worked but ive had enough of it so i'm gonna replace the thing, thanks

[mushed28]

Im just thinking, could it be a faulty thermo senor

[CitroJim]

Get it on a PP2000! Guesswork is not good with a problem like this. A session aboard a PP2000 might well help pin-point the problem plus after you've had the stepper motor out it needs re-calibrating...

[mushed28]

I didnt manage to get the stepper motor out, i took it to a garage and they said that a lead had come out of a senor, but its not different, whats pp2000?

the stepper motor is a small usually black cylindrical device held in by two torx screws,

pp2000 is a dealer diagnostic analyser which some members on here own,

dont they re/calibrate by switching the ignition on and off a few times Jim

never tried Malcolm. I always used PP2000 on it...
