I would start with basics first if you havent already done so....air filter/plugs. could be dis pack breaking down or leads....when was the fuel filter last changed?

I thought it had cut out at that point - couldn't really hear from the budgie that is trying to get out of your glove box :o    :y

That cut looks clean. Can you do paperclip test?

Right, did the revs drop, or was that the instrument that went below 500?  Did the car rev itself, or was that you?

if in gear it will stall no problem on junctions or moveing it around a car park i was reving it as it only happens when im accelarting some times it will do it some times it wont it also sounds as if its fireing on 3 now i think i have narrowed it down to what bank as the inlet ports on bank 2 (passenger side) are black as ace of spades and the ones on bank 1 drivers side are silver also i checked the resistance of the dis pack secondary and primary and i found it to be ok to my spec sheet also bank 2 is the bank with the lamba sensor error im really stuck and i really love the car and it drives nice please help me
also it didnt stall in the video at all u can hear the engine in the background it didnt stall but the rev counter wasnt recording any revs now ive had the crankshaft replaced by a garage and thats next port of call then the cam sensor on the left bank if there is one

If you are getting lamda codes for that bank, and that bank seems to be rich, then I would be checking the lamda and its wiring.

yeah but its been there since about a year and not had this b4 at all i guess the problem has got worse
Title: Re: problem with stalling
Post by: spookyman60 on 04 July 2007, 19:26:39
all i can say is il replace the lamba sensor then the camshaft sensor and then the crankshaft and after that i know where theres either a dirt cheap omega or dirt cheap leather interior and parts

So you've had the lamda fault for a year, now that bank is all sooted up? Hmmm....  ....that makes sense ;)

ok guys ive just got doen off a test drive and guess what i havent replaced a sensor as there all operateing with in values with multi meter and Oscilloscope they where all nice and square wave forms so i thought to hell with it
as i rebuilt it i had cleaned the entire breather system useing a full tin of car cleaner worked a treat found a slightly blocked one but nothing to shout about and a damaged o-ring on the black ecotec bit where it connects to the throttle body i also replaced the orings on the inlet trumpets and it all seems to be ok and damn i thought it was good but its got so much response now its amazeing :D i think this is only a think i have solved this problem p.s the o rings on the inlet trupets where flat but as i replaced most of the others not long ago there proud and suple
