I installed my a/c bypass pulley and decided to run the codes on my car. Well I was figuring I would get these codes ( 24, 22, and 45) since the car runs rich with the 3.4 in there. They all point to the TPS which I changed last week and it is idling better and not as rich as it was. The code thats confusing me is the 42 ( electronic spark timing). I'm not sure what this could be b/c it has no problem starting. Runs fine when its running so I'm clueless. Could it be the ECM or what? Any ideas on this 1?

Thanks in advance.

 

Thats caused whenever you unplug the that single wire (I think its tan with a white stripe) on the passenger side firewall. You unplug it to time the engine. Unhook the battery and it should go away. Or was that 43? I dont remember I'll go look it up.
