#1: Sometimes really slow pull off Author: frenchfrog40, Location: MaidstonePosted: Sat Jul 13, 2013 12:30 pm ---- Sometimes my xsi decides it doesnt really want any power when pulling off. it normaly does it when you first turn the car on. You can have it in first gear with the clutch all the way up and throttle all the way down and it will accelerate VERY slowly and then suddenly the power kicks in. it only seems to be from a standing start aswell or rolling very slowly.
any ideas?

Stuck throttle butterfly sounds worth checking first. I was worried because I just replaced a broken lambda sensor yesterday and that didn't go away!

You need the fault cleared after replacing lambda sensors.
#6: Re: Sometimes really slow pull off Author: vmondude, Location: South WalesPosted: Sun Jul 14, 2013 12:00 pm ---- Yeah I did the whole shebang - BSI reboot and then ECU reboot. The management light and error display were still on for an hour or so's driving but then it cleared.
But today I removed and cleaned the whole throttle body, butterfly valve and all using carb cleaner. And although it seems to run smoother now, it still has the same initial pull away problem. No go at all unless you floor it and then it suddenly picks up like normal.
Very weird that it only does it on first pull away, once its warming up it's fine.
Could it be the plugs maybe? I have a sneaky suspicion that it would have NGK's in it if I looked.
Or maybe MAP sensor or throttle position sensor? Or maybe a choked up CAT after having a bad lambda for a while?

Hmm so not that then. Does it feel better though? I mean apart from the start up problem...

I'm glad I'm not the only one with this problem though, I thought it was a dodgy remap, sometimes its a scary problem when you try to pull away at a roundabout, its like turbo lag on a diesel.
This weekend I'm going to clean and replace what I can to see what's wrong with it, hopefully clear the random flat spot.
Tell me about it! I used to get it randomly too, and yes roundabouts were like playing Russian roulette!! Only get it at start up now though since a good flush with high octane, BSI and ECU reset and the lambda swap. Might help you too maybe?
Thanks for the list, is that for the 1.6 though? As I see it says 110bhp and mines the 1.4, only 90bhp when standard.
#11: Re: Sometimes really slow pull off Author: PugJH, Location: NorthantsPosted: Mon Jul 15, 2013 1:21 pm ---- Yeah sorry the link was for the OP.
110 like mine.
I've given mine a flush but didn't seem to do anything.
I shall give the butterfly a clean at the weekend.
Although I thought maybe it was a signal problem on the FBW

I thought so! Yeah maybe signals, maybe it could be the coil pack...
#15: Re: Sometimes really slow pull off Author: peugeotgti, Posted: Tue Jul 16, 2013 7:06 am ---- Weak spark maybe coil pack as above?
