Alright...finally got around to changing the valve cover gaskets tonight. Also, replaced spark plugs with new OEM plugs. Started the car up to 7 new codes:

Great. Cleared em all out and took it for a drive. After a short distance, it tossed me a battery light and EPC light and then died. Ouch. Started it up again...now it's throwing 3 codes with a CEL ...AND a EPC light??

I have looked up the codes. Cam shaft positioner circuit and manifold absolute pressure sensor...fine. But, WTF is going on here?? My boyfriend and I double-checked all of our work. Everything is back in place after the valve cover gasket job. Hey, at least I am not getting the knock sensor 1 and 2 signal too low along with the internal control module malfunction errors anymore (that was last week). We did not touch the timing... cams were not moved, cam chain wasn't moved. Bad ECU?? Electrical problems is my guess... can ALL of the wiring be replaced? Has anyone done this?? Help please... thank you.

 

I replaced the valve cover gasket on my 03 and it was pretty simple, did you replace the cam seals?

 

so we only replaced the gaskets that were easy to get to. The main reason we performed the fix was because oil was leaking out and onto the spark plugs. It was a simple straight-forward job. I think the wiring is just screwed... probably gonna have to spend a few $$'s to fix this one.
