Well! Heres a fun update!
Did a compression test, and 3 cylinders had compression below 120
1 cylinder was at 40
Did a leakdown test on the cylinder with 40 and a burnt exhaust valve was the culprit.
Did a head rebuild, found out the cam and rockers were brand new! So something good came of that....
Did another etest this morning and it passed on 2500 rpm but failed on idle.
Idle control valve? Any suggestions?
Oxygen sensor is brand new, cap and rotor is only 4 years old, wires are......okay?
