Fuel filter is now replaced. The small line between the pump and filter was kinked pretty bad, and the gas that came out of the filter was just... ugly. Now I have a little more pep. 60 mph comes a bit sooner, and I don't have any hesitation from a stop or from a roll. Onto my new little problem.

After driving about 20 minutes yesterday, I was idling through the parking lot at work, and the engine was just burbling at around 400 rpm's give or take 100. I gave her some gas, and it just dropped back down. It was kind of surging, bouncing almost.

This is only after driving a little while, in the morning she starts and idles fine. I did change the vacuum hose on the FPR recently because it was old and cracked. My throttle body is clean and the TPS adjustment is spot on. I have an exhaust leak, before the O2 sensor in the header pipe, but it never did this before I changed the fuel filter. The AMM is relatively new too. Any suggestions?

Thanks,

Justin
