Maybe it is a ECM issue.

 

that is the box on the passenger kick panel right? how do i test it?

 

i just did a compression test 150 115 45...and then i didnt even bother with the last one...what is the cheapest fix here? should i just pull another one from a junkyard that looks like it has good valves?

 

Check the last cylinder it might just be a blown headgasket.

 

i just replaced the head gasket 8,000 miles ago. turns out the head was extremely warped because i had overheated the car about 5 times in the 16,000 miles ive owned it. its getting severly machined right now... thank you for putting up with all my questions...i should be on the road sometime this week!

 

OK glad you got to the bottom of it.
