Of course, that was paying a shop to do it of course. You could do a coolant system leakdown test to try and cancel out a bad piston and/or verify its just the hg.

I got the scaneer, and it read as follows:
1 of 2 -
code P0303, and undernieth code it says Cyldinder #3 Misfire

code P0303, and undernieth code it says Cyldinder #3 Misfire,

Why did it say the same code twice? Is it because of two different problems that caused the P0303 Code
Thanks

I wonder If I can sue the b***h for 2000 half of what I bought the 97 grand prix for.
She must of known there was a misfire due to a bad head gasket or something, cause when I got the scanner that was the first time ses light came on, since I bought the car for 4000.
