View Full Version : Car Problem
when i start the car up in the morning it sits there idling fine, i pull off the drive and as i get down the street it loses a lot of power, i have to hold the revs high or it kangaroo's, after about 20 seconds this goes and its all fine
it only happens from cold starts, and if i dont drive along and just leave it idling after about a minute the revs just start to drop and it tries to bring it back up, more often than not though it stalls
ive changed the coolant temp sensor twice, the ISCV is fairly new, ive changed the throttle body, TDC sensor, air temp sensor, plugs, leads, dizzi cap, rotor arm, and distributor itself all fairly recently
could the cold start injector be causing it to overfuel ?......
i really need to sort this out as its driving me mad, its happened before and i thought it was me messing with the TB but ive now changed that and its still the same
any chance of it being MAP sensor or Lambda related ?
p.s. my car has Piper cams and a Hill Power chip
Unplug cold start injector and see what happens, failing that try swapping the ECU for your superchipped one, again filing that swap the lamba
the bloody plug wont come off the cold start injector, will have to try again tomorrow
Oh, you have to remove the metal clip thingy from arounf the plug, before you can get it off
small screwdriver, or a swiss army kinfe type thing, you need to unclip and move out of the slot one saide and then the other

Kind of, firsth thing in the morning sometimes, it idles a bit gay, fine after that though, I'm trying map sensor next, but will give this injector thingy a try also
Mine does this as well...don't bother me much...
Mine did something very similar to this. Lamba sensor was knackered. May be worth getting it on a fault check thing...
Don't think it'll be anything to do with the cold start injector as i think that only comes into play in REALLY cold temps. What with you guys being down in England that rules that out! lol
My money is on the lambda for reason you mentioned...
a few have now suggested lambda now, including Nick Hill who really knows his shit, i happen to have a spare in the shed, wont be 100% i dont think but i could try it
Mine does this as well...don't bother me much...
you ever tried anything with yours mate ?
tried the spare ECU, its not that as it did it with that
bought a new lambda but now ive just tried to put it on, the one on the car already is welded on it seems
im still having this problem though its not as bad now, the car doesnt kangaroo it just has a lack of power/bit of misfire, this goes after about 1 minute
its a bit crap cos when it doesnt do it the car runs better, even though the problem goes its a bit more sluggish when its done that start up thing
the revs are no longer dropping after a while, it idles fine
