I've had my new 393W stroker up and running for about two weeks now. I have about 300 mi on it. Yesterday morning on the way into work as I take off and turn at a stop light, the engine stumbles and starts to miss and shake. I'm only a couple miles from the house so I turn around and take it home.
Tonight I run codes and everything checks out for both KOEO and KOER. Since it acts like it's missing, I run a cylinder balance test. It shows that #6 is weak. I run it two more times and get #6 flagged. I check spark plug and wires and everything looks and measures ok. I run a compression check on it and the first time it shows 90 psi, second time it doesn't even pump up. I check #5 and it shows 150 psi. I didn't check anymore at this point.
So, here's the question: what is most likely to have gone wrong? I will pull the valve cover tomorrow and take a look at that. If I don't have compression that would either be a broken ring or valve not closing right?
It sucks to be me. I'm going to have a chat with my engine guy tomorrow. Any ideas or suggestions are appreciated.
thanks,
Renard
