the cat was clogged. sorry for such a delay but thats what it was.

is it possible that bad plugs could cause it to over heat? wouldnt bad plugs, misfires, trip a code for obdII?

atf is fine, full and red. smells good too, i drain the pain almost every time i change engine oil. overflow tank is empty. when it was overheating is was flowing out the overflow on the tank, but as it cooled would be drawn back to the rad. i have filled the rad but not the overflow i will do...

i think i have a bad head gasket. absolutley had no way out of it, but i HAD to run up the highway yesterday, and it overheated. stopped several times and thought to myself check the oil. its overfull by 1.5 qts. :-( bad head gasket could also suck air and engine would hit a wall under load. or...

75w90 front and rear, synthetic or conventional your choice. if you want to tow or heavy duty anything put synthetic 75w140 in rear. no additives required unless you have a limited slip (which would be aftermarket usually) if so then consult the aftermarket manufacturers specs.
