***JB4 map2: Only DCI and Muffler delete***
I've been running jb4 map 2 for a about 10 months now and up to about 2-3 months ago when I go WOT getting onto the freeway for example.. I get the half engine light that pops up. Nothing happens but when I give some gas the car shakes. If I don't touch the gas for a couple of seconds the light leaves. Does anyone know what is up? I've tried map 5 and same thing happens. It isn't a constant thing. For 1 month it'll do it then the next month it won't. Any help?
