Message Need some serious help. Just put my engine back in about 3-4 weeks ago. Car ran great, better than ever.
Started it yesterday and it ran rich immediately on the passenger side and no power.
Got her back to the garage and here is what I know:
Pulled coilpack connectors on 1,3 and 5 - no change in RPM
Changed plugs in 1 and 3 - no change (covered in gas)
Checked compression in 1 - ok
Changed coilpacks in 1 and 3 - no change
Pull coil packs off of 1 and 3 when car is running and you can hear what sounds like spark shooting to the plug.
New wiring harness was installed when the engine was out.

Do you think its the PTU? Would it affect it like this? ECU is showing code 34, but i'm sure that's cause its not firing. Any help is greatly appreciated! Thanks!
