Got my timing and pass side manifold changed and it purrs like a kitten...however it bogs down if I try to gun it from a stop or if I try to go over 45mph...anyone have any ideas?

 

Anyone??

 

Any codes? Could be number of things possibly coils, injectors, plugs, cats, fuel filter, fuel pump. If I had no codes I would start with checking your fuel pressure at the rails to make sure your fuel pump is giving you proper pressure.

 

No codes at all except for when ign wire 3 wiggles off cause I broke the clip...imma fix that with a zip tie

 

Sounds like you have your solution to the problem....

 

I can tell when that slides off...it throws the code...

 

Even with the musfire previously it didn't bogg down like this

 

Just got a bank 2 lean code

 

Lean would be a fuel problem check your fuel pressure and check your fuel filter more likey it's that over a injector but it's possible a injector but you won't know till it gives you a cylinder code.

 

Cats or injector... I'ma vote cats....
