i just rebuilt the sc engine and put it back in. when i run the car it runs real rough and there is a pinging sound in the exhust. i thought is was running bad because the gas in it was sitting for 2 years so i dropped the gas tank took all the gas out and put a new pump in and changed the fuel filter, but its still running rough. can anyone help me out.
 
Sounds like some sort of sensor... not that up on the sensors but could be an O2 sensor or something along those lines. Did you double check your intake seals. The engine may have found a leak in a seal and not producing any vacuum.
 
How are your cats? Maybe they are getting bad and breaking up and blocking off the exhaust. Just a thought for something to look into. You wouldn't want to blow your head gaskets over it.

the cats are fine, they are completly clean, i'm going to look into the o2 senors, see if i can find any solutions there, but thanks for responding. if anyone has anymore info please post.
thanks
