Hey people got this problem with my car I'm hoping someone can help me with as its really annoying me especially when you get some guy in an mr2 next to you revving his engine and tries to race and your only a car length or two in front!
Ive got an Astra Gsi and its running CS3 map, what happens is;
If i pull off and give it full throttle and change gear at the top of the rev range (not redline) sometimes it starts miss-firing and the engine light will flash, however a quick turn the engine off and on and its fine again, it doesn't do it all the time and I'm thinking maybe coil pack due to the turn off engine and on stops it....?
I had a coil pack go before and it seems very very similar although this doesn't happen if i change gear early.
Any help would be great!
Also thinking could it be: Plugs, Knock sensor?
