i have a stock gslse, it wasnt holding idle very well so i replaced the throttle body with another one. idle problem fixed, but now it backfires when revved above 5000rpms.

so would is it neccessary for me to re-do the timing? all i did was change the throttle body. should i just turn the srew for rich to lean all the way to lean?

any advice or suggestions? thanks for your time.

 

Did you reset the tps?

 

reset? do you mean re-check the tps

 

would suggest checking timing, probably running rich. just my opinion.

 

adjusted tps and no more backfiring
thanks for the tips
