In troubleshooting the engine in question, cracking lines will find you the trouble cylinder.


New parts don't mean anything. If you have a mechanical issue that's developed since they were installed then you have an unrelated issue that needs a fresh eye.


You keep going on about low compression and starting performance. Get over it. You can have 5 healthy cylinders and 1 lousy one. If any of the 5 healthy ones light off, the car will start right up with a crap idle from the missing cylinder.
