ok my car is acting funny. its not starting anymore after my mfpi swap. it started before but now its not. what should i check first. also im throwing 2 code. a code 4 and 16. but dont worry i know what those codes are.

 

Well if you know what those codes are...start by clearing them. By fixing those, your car should start/run correctly.

What information did you want?

 

the only code im having real trouble with is 16. i really dont know what to do.

 

More than likely it's your wiring that is the problem. Double and triple check everything.
