Before replacing the fuel pump, try the Fuel Pump Relay Bypass mod in the Links section of my webpage.

It's quick and easy to do, and it costs nearly nothing to try.

 

I was on my way to NAPA to order a pump when i saw my friend, a mechanic, in the parking lot. He told me it could be because of bad back pressure in my exhaust. I knew I had a leak some where before the cat but I didn't think that could be the problem.

I told him that sometimes the problem clears up once you get to about 3000 RPM's and he said it could be beacuse of the leak and since I was going to get a new downpipe and test pipe, told me to try that and see if it works. The only thing I don't know is if the leak is on the headers or downpipe, which isn't a big deal because I am going to look at that tomarrow. Do you guys think it could be because of lower back pressure?

 

An exhaust leak might cause a small hesitation, but I would think it would be barely noticeable...

 

i would agree with thestealth, unless you have huge leak you should not see much of hesitation. I drove with a leak for a month without any hesitations, i didn't even noticed the leak untill i went to muffler shop

 

Hey just a follow up. I replaced the downpipe and the problem went away. There were a few holes in the pipe and that was the problem. No more hesitation/stuttering. Thanks for everyones help!

 

Good news. Sometimes simple things are often overlooked or not considered.
