ok , i installed edelbrock headers, Now my car backfires through the tbi, wtf caused this, how do i fix it ANY suggestions or ideas???????????

 

Backfire thru the intake, usually means a lean condition, you didn't touch the timing did you?

 

Check for swapped plug wires and large vacuum leaks.

 

ok seeing how i took all the wires off, im HOPING this is the problem.....thanks for the help so far....for real. i dunno wtf id do if this board wasnt here. guess id shell out money to a shop for a simple error. i very well may have accidently turned the distributor in the proccess, ...everything under my hood was pushed and pulled at least 100 times lol
