hi guys i have recently ran into a problem with my car its spitting when i hit boost. hi have tried the coil and have checked dizzy. i also took off the boost controller and left it open (it over boosts) the only thing else i can think of is the fuel pump. have you guys got any ideas.

Double check the dizzy, I had a small crack in my rotor, which was expanding when it was getting hot and causing the car to miss. Crack was real hard to spot. Fuel pumps are problematic, but not sure how you can test em. The other thing is a valve, can't quite remember what its called, but its something like pcv valve or something. I'm sure someone else on here will know what i'm going on about!

if it was the fuel pump wouldnt it just cut out completely ?

could be heaps of things.mine use to do it until i moved the plug leads away from the crank angle sensor and were arcing on the cylinder head. goes sweet as now.could be that.just check ur leads, dizzy and air flow meter.is it a factory turbo motor or a n/a converted?

thanks guys noticed one of the leads was a bit burnt at the end of it so replaced the lot should be running sweet for the brock cruize.

spark plugs

put some petrol in it.....................just kidding LOL hehe
