Ok so we changed the injectors and blew the ecu fuse after that it worked (i replaced stock injectors) My car ran as normal for like 15 i took it on the freeway to make sure everything is smooth... after getting off the freeway my car starts shaking ALOT! the rpms dropped way down and after that it wouldnt go past 3 1/2.... (aka limp mode) Also my exhaust sounds a lot different (like a damn diesel truck) and it shakes like a bitch

I checked a couple things but what all should i be looking for?

Thanks a lot

 

BUMP????? Please help somone
