#1: Strange Rev's Problem Author: MrrNoName, Location: UKPosted: Tue Dec 28, 2010 9:12 am ---- Hi all, my pug has developed a revs fault.
when the revs are dropping they drop down normally (at a normal speed) untill they hit just above 2k. then they take a looong (3 seconds ish) time to drop from 2k to idle.
this happens both in gear and in neutral. also when then engine is hot and cold.
It makes it annoying to drive as its hard to match the revs when changing gear.
throught maybe it could be an air leak, but dont really know where to start looking.
the EML is not on. any help would be appreciated

What year of 206?
These simple details about the car in question that a lot of people don't bother posting up actually help us work out the best advice to give to solve the problem.

Normally 2 x torx 20 screws hold the stepper motor in, don't loose the O ring seal on the end & DON'T try & unscrew the plunger from the motor!

#7: Re: Strange Rev's Problem Author: MrrNoName, Location: UKPosted: Tue Dec 28, 2010 11:09 am ---- not too sure what the stepper motor is or does tbh.
what would be best to clean them with?
#8: Re: Strange Rev's Problem Author: MrBSI, Location: What's it to you? ? ?Posted: Tue Dec 28, 2010 11:13 am ---- Stepper motor helps control the idle speed of the engine.
WD40, some paper towel & some cotton bud that you clean your ears with are all you really need to clean the plunger & the air bypass hole.

#12: Re: Strange Rev's Problem Author: MrBSI, Location: What's it to you? ? ?Posted: Tue Dec 28, 2010 11:45 am ---- Follow the throttle cable to where it links on to the throttle spindle / butterfly.
Look on the opposite side of where that linkage is & you should see the stepper motor.
Number 4 is what you are looking for.
#13: Re: Strange Rev's Problem Author: MrrNoName, Location: UKPosted: Wed Dec 29, 2010 3:35 am ---- thanks for the advice. i will have a go. anyone else got any ideas of what it could be if its not this ?
im a little unsure as it doesnt struggle once idleing. i.e the revs take a while to go down to idle but once they are at idle they run consistantly at the correct revs, every time. no stalling. no high idle etc. they just take longer to reach idle.
