Ok i have another problem with my car. I'm really not too worried about it because im storing it in 2 weeks so i can work on it. Ok here's the problem. One of my spark plugs blew out of the head the other day. I have a re-thread tool and re-theaded it. I drove it and now there are a few problems. When i get on it there is barely any power and when i put it in 5th gear and hit the gas it bogs alittle. im thinking it's because when i re-threaded it i may have screwed up the head. But i just want to make sure that is the problem. FYI, my car is a 93 Z24 5-speed. Any ideas would be helpful.





Thanks,
Nick

spark plug blew out of the head?? something stuck in the cylinder?
my best guess would be get a compression gauge and make sure that cylinder is still holding compression.
