Today is gash, i took my sensors off and gave them a blast with WD40, and as per usuall when the car is cold lovely, no problems slow down for a junction dip the cluth from any rev range, no problem it floats back down to 1000 rpm and no hunting. When its warm, if i leave it in gear upto about 1500 rpm and genteley dip the cluth it goes back to 800 rpm and hunts abit. If i dip the clutch any other way the revs fall dramaticcaly to 500rpm and hunt there way back upto 800 rpm, but 5/10 times it just stalls. This is not a new problem, ive cleaned my stepper,sensors. Please help me out people, i dont know if its since i had it bloody "superchiped" or not?

I get this some days, especially when it's damp and the engine has warmed up. Slow down to a junction and the revs dip down to about 500rpm and it either picks back up to 800rpm or just stalls. I've cleaned my stepper and induction side loads of times and think it's time for a new stepper. £35 off e-bay for an OE part - not bad.

I get exactly the same problem, but as you said it is only now and again. Its a pain in the ass

cleaned my stepper again today (spotless from last time) and put some plugs in it, the coil packs are sagem ones dont know of these are origanal? but im in the proccess of getting some more, also ive beefed up the end of the pipe which comes off the end of the stepper so its air tight going into the next pipe, will see what happens when i get coil packs?

I've got an ebay stepper. Its shit, its not idling properly at all now, goes up and down like a twat or just cuts out.

Don't bother, get the OE one from ECP, though i think they are closer to £100

Sounds TPS related pedro yeah.

I ordered a stepper from ECP today. £67 with the VAT but worth it for the peace of mind over the ebay special I think. The worst thing about the stepper problem is not just the stalling at junctions and looking as if you have no clutch control, but also stalling on bends/roundabouts and losing your powersteering mid turn and having to wrench the wheel round without it and not drift into another car or a tree or whatever while restarting your engine on the turn to get all the power back!

ive made progress i think, did an ECU reset and now when the engine stalls the engine mangement light (orange one on top of airbag) comes on, does this tell me its definately sensor related? also the idle has gone back to hunting between 800 and 1k rpm

could ECP be supplying the wrong stepper? i phoned them and they were sure the part i bought was for the XU10J4RS as well

I placed my order with ECP at 11:20 yesterday and had the stepper delivered this morning at about 10am! Couldn't believe it for service!

I searched their website by the Peugeot part number 1920v7 which brought up a stepper listed for loads of models including the 306 GTi-6 XU10J4RS so I knew I had found the right one and was impressed that their site recognised the Peugeot part number. Their part number for the one I got was 410735010 so check that against your invoice pedro.

I fitted mine this morning and went for a long blast. Didn't have any problems at junctions or on bends while the engine speed was slowing. The rev needle just drops to 800rpm dead every time with no dipping or hunting. Perfect.

Pedro did you do an ECU reset when you changed yours? This is vital as the position of the new stepper will be different to the old one you removed and the ECU will be confused as to how open or closed the stepper is and will misbehave. The ECU reset forces it to relearn the position of the stepper. If you have done this I would check your wiring and connector contacts.

The EML means there is a fault code to be read, that's all and this will probably point to the problem part.

Changing sensors is easy enough to do yourself with some basic tools and common sense. The TPS under the throttle body can cause problems for some people and also the MAP sensor. With a new stepper fitted, you need to start looking elsewhere for the problem. To answer your question about diagnostics, I doubt it is ever 100% guaranteed to identify the problem part correctly, if at all. It's probably just as well to use some common sense and trial and error to see what happens. There is a sensor testing FAQ on the forum so that you can check your sensors to see if they are operating normally - why not give that a go?

my problem seems to have got worse overnight, car wont start at all now

turns over then just chugs and chugs, briefly fires up but revs wont go higher than 500 then dies after 5 seconds, definitly not firing on all cylinders but could be spark, air or fuel related, fuel pump primes as it always did no nasty noises or anything

might as well start with the spark plugs anyone else got any other suggestions or how i can check to make sure enough air and fuel is getting in on start up

Mine was like that for a while tog, clean it up, ok for a while then starts stalling, rinse and repeat. The trouble is the time between cleaning and misbehaving gradually gets shorter until you are always having to clean the bas**rd thing! This is what mine did so I figured it was well on its way out. I replaced mine and it's been perfect since. I'd go ahead and get a new one if I were you mate. Stalling can be dangerous, especially on bends and just plain embarassing at junctions/lights etc

my VTS stalls only when I have to suddely depress the clutch , but when I have time to use enginebrake it's fine. I believe the stepper doesn't react as fast as it should!
And as everyone said it's fine after cleaning... for a few days...

Did the stepper last week, perfect now when dipping the clutch at lights, junctions etc.. apart from now when its idling at 800rpm if say im parking up and move forward but only get upto 1200 rpm in 1 st before dipping the clutch to put it into reverse my revs fall sharply to about 500 rpm and pick up again (its not stalled yet)so my problem is 80% sorted but im scratching my head a little still?
