I haven't had that checked out yet. I'm now dealing with the dreaded P0300 code that tripped last night. I'm going to check for vacuum leaks. I replaced the camshaft sensor (I had a P0302 code earlier yesterday). I do have a crankshaft sensor that will be delivered today as well since my old one is shot.

The overheating issue was caused by a radiator crack. I've since replaced my radiator and I'm no longer having overheating issues.

 

When the new crankshaft position sensor is installed you will need to have a crankshaft relearn done with a capable scanner. This will set the timing. Then a a camshaft sensor relearn should be done also. Good luck

 

You are right. I was thinking of a different vehicle I have. Sorry and thanks.

 

Given your mileage issues, what are your short and long term fuel trims at idle and 2500 rpm? This can also help diagnose a vacuum leak.

Misfire codes mean that the crank sensors sees a velocity hick up. Could be spark, compression, fuel or vacuum.

Have you done a compression test?

Have you verified strong spark?

What is your CMP retard value?
