thanks for your help bro...no, car runs perfectly fine but idles rough when i start it up at night but i can jus clean the tb and iacv, and seafoam it...any other symptons u think this could be lead to?....i need to take my oil pan out on my next oil change....i "think" the previous owner turbo'd the car cuz i see a vacuum line being tee'd off...could that be the culprit?

#71200 Possibly an exhaust heat shield ie the cat converter's upper shield. Jack up the car and have someone rev it in neutral. Or take it to an exhaust shop.

#83298 Just make sure its not a rod knock before you keep driving and get stranded somewhere with a hole on your block.

that hole in the block wouldn't have anything to do with your nickname .. at all?

"Revin hears a slight rod knock and shoves two pedals to the floor, bet you can't guess which 2"
