Have you done a leakdown/compression test? I ask because my "healthy" engine developed a misfire right after the stage 3 parts were put on and it turned out to be burned valves. If the misfire codes move from cylinder to cylinder I would think you have an air leak.
There was a compression test done before the codes were thrown and everything was good.
I clear the codes and drive for 3 miles or so and then let idle and 5 mins later I get p0171 then clear code and drive for a few more miles and let idle then throws p0301 and p0303. Clear the codes drive a few miles and throws p0171 and so forth. She runs great which is odd I would think for these codes. No rough idle or hesitation.
I had some trouble mounting the Torque Solution TMIC its so ******* tight fitting I think that I may be causing a vacuum leak from the install.
Could it be from the GS ebcs being installed with just the base map?
I dont understand how she could be running so smooth with no hesitation with misfires seems strange to me I would think that she would run rough from those codes.
Thanks again guys for the help!
