car misses when you put the gas to the floor!

[kadeas]

Hey all,

When I'm doing around 35 or so, andI put the gas pedal to the floor, the car jerks and misses bad, then if I let off a bit it kicks down and takes off!

Anyone had this problem, or know how to fix it?

Thanks for all your help!!!

Sounds like a classic case of a clogged fuel filter ...

I had to change the fuel pump 3 times in the 4 years I've owned the car, it seems to go out once a year, could be cheap Auto Zone parts? Oh well it's free replacement. The filter was changed about 2 years ago, and I noticed this prob about a year ago. I was told it was the throttle cable. And it only surges with acc. pressed to the floor, not when at idle or normal take off. If I floor it from a dead stop it runs fine, just if you're going down the road and floor it, like to pass someone, is when it misses.

I change the fuel filter every 6 months.. when they're so cheap, why not?

be ware of cheep fuel pumps.. i forget the brand that alot of parts stores stock, but do yourself a favor and get a good AC Delco pump.

your problem sounds so similar to mine...except opposite situation...mine will take off fine if i floor it, but it kinda surges and misses when i take off easy...

Could it have anything to do with the egr port being plugged? I have a code that says egr valve 3 is sticking, it happened before, dealer said port just needed cleaned out. How do I do that? And what kind of solvent should I use? Could it me the throttle cable needs adjusted? If so how? It's almost like it's trying to kick down into the passing gear but can't.?????
