Misson complete no leaks but I do have a new issue. The car has a horrible rough idle and shutters really bad if you try to drive it. Its nearly undrivable. I was cleaning a lot of the parts as I took them off and I'm wondering if maybe the simple green I was using externally on the fuel injectors have caused an issue. Its the only thing I can think of.

I replaced the spark plugs while doing this project and the wires, coil packs, fuel filter, fuel pump all less than 4000k miles old.

Any ideas guys?
