SR20DET trouble

[mayhemsurfer14]

Hey guys I have a redtop sr20 with an enthalpy ecu. Was running fine, would drop rpm's then come back up when put in to neutral but other than that it was running normal. The other day I was driving and it starts running on 2 cylinders...

I already checked and tested the injectors, cas, and coilpacks. And the wiring to the coilpacks and the ground. Anybody know what might be wrong? Help Please!

Thanks,
E

Bad spark plugs?

Did you swap your maf out with another one as a test?

Also did you do a really good vacuum leak test?

Another possibility is the harness. It could be a weak connection on a hacked JDM harness. Hacked JDM harnesses are the cause of most random issues electrical wise on SRs in my experience.
