Here's the scoop...I also have a 95 T bird LX with a 4.6 interceptor (police car) motor. It lost power and started running real rough. My brother in law helped me check compression and it all seemed to be ok. But the dumbass cross threaded one spark plug and another one the ark was bent all the way down to the plug but I did not know this until I got the car home and changed the plugs. Changing the plugs did improve it some but it is still running a bit rough and I am affraid the one piston where the plug was bent is damaged. Is there anyway to check this for sure without pulling the heads? I am afraid to even start the car so not to do anymore damage to the motor just in case. A local mechanic is wanting over $1,300 just to redo the heads. Any ideas?
