I have a 2010 chevy camaro ss1 with 80xxx miles , when WOT(wide open throttle) in 1st and 2nd gear(10-40mph) it will accelerate for a split second and then begin backfire and pop and seem to not be going anywhere and losing power when it does so, and will go away once I go into 3rd, or if I'm going from 1st it will do it and then I'm 2nd and then go away in 3rd. No check engine light is on, changed plugs and wires and new air filter and still does it, only does it after the car is warmed up.... PLEASE any ideas ??? anyone? The car is stock with no tune, just straight piped. From one camaro/car guy to another, I thank you.

 

what rpms are you turning

 

It starts to do it at 5 to 5 1/2 thousand rpm or is that not what you meant im sorry I need the advice!

 

Weak coil, plug, or plug maybe?

 

im wondering if the limiter is set at 5 or 5.5. it would most likely back fire through the exhaust burning off excess fuel.
