Hello all, I’m running into a huge problem on my speed 3. I’m having a cylinder 1 and 4 constant misfire. It will randomly stop and run fine then go back to misfiring. Recently it has not stopped misfiring.
What I have done:
  • Spark plugs replaced and gapped
  • MAF replaced
  • Set of fresh injectors from cwturbochargers
  • New battery
  • I switched the working coil packs from 2 and 3 and put them on 1 and 4 and they were still misfiring
  • Compression was: 1-135psi 2-130psi 3-130psi 4-125psi
Compression test was done on cold engine. I know it's low but it should still run without a misfire right? What should I check next?
