RPMS jump around at WOT!?
I dont think anybody that owns an lt1 has the answers for the mystery miss all our cars have. My car had a bad miss somwhere and i cant track it down. At Wot you can visibly see the Rpms jump up and down. The motor is breaking up really bad. Less now that i disabled the EGR, but my SES light always come on after the car warms up and it still backfires and stumbles. O2's have been changed, coil,1le intake elbow,Iac cleaned,new opti,wires,plugs, the works. I cant figure it out. I also have an exhaust leak on the drivers manifold but i dont think thatz the culprit. Any ideas would be appreciated guys, and ill tell you if ive tried it.
