Seems like i remember a vacuum leak problem with code....perhaps intake upper and lower manifold gaskets...anyone had this problem and fix?

You can do a propane leak test to check the gaskets Some times if it is a small leak the liquid may not go through..

You may have to have a scanner, not a code reader hooked up, and read each sensor..

I had the same thing happen to me. I checked for leaks couldn't find any. So I disconnected the battery. Drove 3000 miles and the CEL light came on with different codes misfire cylinder 4 5, and 6 detected. So I am going to replace the plugs and wires. see what happens next.

Weird!!!:wacko:

Who was pushing? :lol::lol::lol:







Sorry, I couldn't resist...
