Hi all. Under hard acceleration, going to pass someone or going up a steep mountain I starts to stumbling and bogging down. As soon as I let off the pedal it runs fine. Seem to be happening only when its hot out. Change spark plugs, wires and cap and rotor, also fuel filter. Anything else I should be looking at. Thanks for the help.

 

Alternator. Auto parts retailers test for free.

 

Check injectors too

 

Fuel pump, maybe. Sorry about the multiple posts, trying to think on my feet

 

Alternator is new. Fuel pump had crossed my mind. Guess I'll check fuel pressure. Thanks for the suggestions

 

Good luck
