ok after about 10 minutes of driving, there is a rotten egg kind of smell
that comes from my car. ive heard that its a symptom of bad O2 sensors
any of you kno?

i recently changed the cats and when putting the old O2 sensors in one of
them got covered in grease that was all inside the threads

could this be the problem?

Whats your timing and Fuel pressure set at?

I would run a code tester first, before spending all that money.

well ill run a code tester first..thx

hmm I just posted on your coolant leak prob, I'm thinking cause-effect here. Cats make a rotten egg smell when they are getting clogged and fusing together, mostly from too much raw fuel. I could be wrong but I'm thinking bad head gasket-cylinders burning coolant-coolant mucks the O2 sensors-PCM runs engine rich-cats get clogged. For your sake I really hope I'm wrong, don't let me scare you I'm just guessing. Keep us posted as to what you find.

i think lazlo is on the right track. have you pulled your oil dipstick and looked for water/coolant mixed with the oil?
