Can't accelerate past around 35-40 mph. I hear a popping sound on drivers side and smell what could be burning plastic or rubber. I can have petal to the metal and it stalls but you can hear the engine revving. I do not think it is an engine or transmission problem. Possibly fuel pump? When I shift into park and back into drive it resets. Does anyone have any ideas of what it could be?

 

We had a Monte Carlo years ago with top speed of 35 - 45 mph. Replacing the catalytic converter fixed it.

 

codes?

 

Smells like a clogged cat...
