for the spark i have tested the coil packs and plug itself and they both work... were should i start to find where the problem is?
for the fuel it seems that one of the fuel injectors are not sitting right and if im correct doesnt that mean extra fuel is getting dumped and would that cause smoke to come out of the tail pipe or not? is this correct thanks

Re: Spark and fuel question (nathanmoris)
Sounds like it's not the PTU but more the injector seating. The PTU did have a recall (note - if the PTU is black plastic and hexagonal, then the recall has been done....if the PTU is a big black plastic square, then no it hasn't). But for your problem it sounds like this isn't the culprit.
Sounds like you have a leaky O-ring around an injector ( 2 O-rings per injector, plus on injector insulator) or the injector was not placed in correctly (use a 1/4 turn on each screw rotating between the two method when tightening down the fuel rail caps to press injector down into the rail, is the correct way to seat an injector into the rail). If the injector isn't sitting right you will get a number of problems potentially...fuel starvation which may lead to detonation (in extreme cases), fuel flood causing fouling on the spark plugs, injector failure, etc.
My advice...pull the injector if that is in fact what the problem is but after making sure the coilpacks are all good. You can test the coilpacks by running the engine and pulling each coilpack individual. If the car stumbles after disconnecting a coilpack, then that one worked and plug it back on. If the car doesn't stumble, then that is your back coilpack.
