Hi guys. I've decided to expose my problem maybe someone has any ideea. I run stage 2 EDS map on my Z20LET and for a while i am having some problems. First of all, let me just say that this has happend before. When i got the car, it was having the standard exaust, it was changed only the precat and the cat with sports cat. When i was in 5th at 100 MPH I accelerated on the highway, when it starting going in hops, interrupting the accelerations then the check engine light come on flashing and the engine was going in 3 pistons. After restarting the engine, everything was ok. I thought that was because of the poor petrol that we have around here.
After this incident, i have managed to change the exhaust with this one ( http://shop.loonytuns.de/Sportauspuf...ucts_id=35066& ) and since then i am having this problem with the interrupting in 3, 4,and 5th gear. The problem is that is doing this only if i floor it from 3000 rpm. If i am kicking it down from the start goes like mad.
I've changed the coil pack twice, i've checked the spark plugs and i must clean also these days, the acceleration chamber.
Has anyone had or heard of this problem again?
Thanks in advance, much apreciated.
