![]() ![]() All spark plugs are new with only a couple of hours of troubleshooting on them.Ran the engine with the spark plug and coil pack (from cyl 4) sitting on top of the valve cover looking for a spark when running but we did not see any.So it would seem that the cylinder is ok. Next we did a compression test on cyl 4 and it came in at 180 psi.We restarted the engine and it ran similarily rough with same results on the Code Reader. Swapped the coil pack between cyl 3 & 4 but not the spark plugs.We checked the elect connection on the coil pack to ensure it is plugged in completely and it seems ok.Installed a BlueDriver code reader and it says "engine misfire cyl 4". ![]() ![]() Here is the troubleshooting we have done in the last day or so: It started right up and ran ok for 20 seconds but then seemed to start misfiring and running rough. We have now installed the engine in the car and after started it for the first time in 2 years. When purchased it ran very poorly misfired on cyl 4, no compression on Cyl 4 (Other cyls have 180psi) After much amateur troubleshooting we removed the entire engine and took to a rebuild shop where they completely rebuilt the engine. I have a 2007 R56 Hatch that my son and I purchased as a project vehicle. ![]()
