SOHC running rough

[ekrampitzjr]

It's easy to install the plug wires in the wrong order on the coil pack. Ask me how I know. Look again.

No code yet. I have been letting it idle for about 40 minutes combined for the past few hours, it will run fine for up to a minute before running rough, and then go back.

Sometimes it takes some time. As long as you don't do any long drives anywhere, your cats will be fine. It takes a lot of driving and poor fuel trims to ruin them

I have driven it a few places, I also took each wire out, tested it with a multimeter, made sure all the wires were in the correct spot, no cracks in any of the plugs. One of the wires was testing a little off, I replaced it but still. Issue persists, no trouble codes yet.

Check your plugs. If one was dropped or pressed too hard during installation, maybe the electrodes are touching or too far apart instead of having the proper gap.

Solved, Cylinder 6’s plug had a hairline crack in it. Replaced and runs perfectly. Thank you all for your help
