right the other day i stalled my car,when i restarted my car to drive away it began to missfire. Already i have changed coil,plugs,leads,the whole dizzy including cap and arm, and i cant seem to find what it is, it only missfires when under load e.g pulling away and i have had a compression test and every thing is fine their and i have changed the ecu and it still missfires. I have a s2 rs turbo chipped,1.8zvh and a stage 2 turbo if that helps...............................plz i need help

 

I had this problem with my last turbo-it was one of the red fuel lines that go from the meter head to the injector.Was weepeing fuel out and loseing the pressure, so fuel wasnt getting to the cylinder.
hope thats something helpful fela

 

yea i could have a look at that, but also when im driving it missfires when i put my foot right down but if i slowly really slowly put my foot down is dosent missfire????????????????

 

sounds as though it could be summit as above mentioned...

 

i had the same problem in my rst was unable to go over 5000 rpm without missfiring like crazy and if i squized the accelarator slowly it was good, try checking youre crank sensor, it should be counting ignition from the flywheell, a littel carburator spray on it did the trick for me, in case you'rs got dirty it should help. if not the try replacing it ....

good luck mate !

 

checked all the red hose lines and nothing, all looks good no leaks or splits, i just dont get what is wrong with the *#"% thing

 

o and one question where is the crank sensor ?????

 

Have you set the plug gaps right?? if there not set right that can make it missfire.

 

crank sensor should be mounted near the flywheel (buttom part of the gear), look under the car and you will see it, there is a slight chance that it mounted near the crank pully (bootom pully) also check there if it wasent found on the flywheel,
search eBay for a crank sensor or a TDC sensor in order to get an idea on how the sensor looks like, again i had the exat same thing and that was the problem for me....

 

If his rs is still on the factory management (MFI) it wont have a crank sensor.

 

yes i still have factory management (MFI) apart from a chipped ecu. I got such a headache i just cant find whats wrong with it?????????????????????? would it be a good idea to check the cam ???

 

did you go set mixure? no %CO , I mean on mixure by regulating fuel pressure actuator.
