If you over tightin the 3 bolts that hold in the fuel rail, does that cause the engine to misfire? i am assuming that there is a leak in my fuel system becasue the check engine lights keeps jumping a CYL. 2/CYL.3 misfire code.
I did put in new injectors on a AEM fuel rail with a B&M fuel Pressure. Reg.
Could it also be my seals on the injectors that are leaking!!???! plus on my fuel pressure gauge the neddle goes back and fourth extrmely rapdily, guessing that there is a leak in my fuel system.

 

My fuel pressure gauge goes back and forth rapidly too. That is with the car on. But i also have a problem with low rpm misfire. Kinda like a really bad bog. But i'm not throwing codes. If you car misfires do the GSR ecus tell you? Or does it have to be really really bad?
