98 GT missing on 2 cylinders
Hi all,
My motor is missing on 2 cylinders, the tuner said he thought it was broken valve springs, but I think that is unlikely on 2 cylinders. He tested the compression and said it was good, but did not do a leak down. My plan before ripping into it too far is to check: Compression with a leak down check as well, check for spark, check for injector signal(noid lights), the injectors are brand new FRPP 39lbs injectors so the should be good ( also had the issue with original injectors). Fuel pressure was tested and was good. Maybe check injector signal strength?
Any other suggestions are welcomed. I have an SCT handheld if that can do some diagnostics.
