Just recently whenever i start to press on the gas pedal the car stutters and then smooths out. One time when i started the car it died on me. Im not sure why it started doing this. The wierd part is sometimes it works fine, and doesnt stutter. I was traveling on the freeway the other night and all of a sudden my car would lose power.. like i would press on the gas and it would not register it (as if the gas wasnt flowing) and then the power would come back.. this happens every now and again. It is hard to explain. Then after It did it a few more times, my car backfired.. and smoke came out of my mufflers.. its never done that before! Could cracked headers or exhaust pipes be doing this? It feels like ive lost power even when its working fine. My exhaust pipes sit very low near the ground and they have hit the ground a few times.. so if there is a crack which i cant see, could it be the reason as to why my car is backfiring and stuttering like it is?


Thanks for any info you have.

Sounds like the symptoms of a worn cam lobe. Does it get hot while this is happening?

Before you jump to the conclusion that you have a flat cam:
Check that you manifold and carb vacuum lines are still connected. Also, with the key off, depress the accelerator linkage on your carb and make sure your carb's internal accelerator pump is squirting out gas in both of the primary venturis.

I'd also check your fuel pressure and see if you don't have a partially ruptured diaphram in the fuel pump (barring that you are running a mechanical pump?) Might be something to look at!


Best of luck,
Tom

Years ago I left work for home 30 miles away. The Camaro ran fine for about 5 miles, and then it wouldn't go faster than 35 mph the rest of the way. My problem was nothing more than a partially plugged fuel filter. Changed my filter, never had that problem again.

Sounds like a lean condition from here in Boston...
