hello all, I'm new here and I do most of my repair, cause don't trust anybody working on my car......I own a 1972 corvette and 1999 chevy Tahoe with 179,000 mile and still love it..........but now I got a PO300 reading on it. What happen was driving down the hiway at 70mph and then felt it was misfire then engine light came on and plug in my ODB 2 and read PO300 went home change spark plug and notice #2 plug was foul but no help here so now wonder what next to do and I do know there lot of other thing to do, but trying not to spend so much on the things that don't need changing.............but I'm thinking it under the intake which is the injection spider. Been reading and checking what other seen to find out. Any help would be great. Thank Mark
