I saw this posted on another automotive forum and it just floored me..... thought your guys would appreciate this part of a post by a guy who thinks he know what he is doing:
"I didn't mention all of the attention and tests that the tuner gave to cylinders 1+2. He showed me that cylinder #2 was clearly not detonating with regularity and was fouling and missing intermittently, even though it had excellent compression and new plugs/wires/cap/module. He felt that this was actually caused by a blown head gasket between 1+2 or a valve issue. Blah, blah, blah,....."
Not detonating with regularity?!? He had posted earlier that he and the tuner has measured 210 psi cranking compression on cylinder 2, 3, and 4! When I posted that was way too high for an iron headed NA engine.... he just kept on going....:wtf: Not the first time this guy has ignored solid advice.... and he wonders why his engine is having issues.
You just never know....
