This just started yesterday after I filled up at a gas station. When i'm at a dead stop or driving kinda slow and I hit the gas it kinda hesitates a little. Anybody know what that could be. I noticed my oil pressure was just a little below 30 on the gauge. Maybe just some bad gas? Sometimes when its in park and idling and I hit the gas I swear I hear a little bit of a misfire. Could that be related or a different problem?

When mine started stuttering at low rpm (right after a shift) and at take off, it was the fuel pump going out.

I've been trying to solve a similar problem for a year now. I replaced: Fuelpump, fuel filter, Distributor, ignition coil, plugs, TPS, CTS, cleaned IAC, wires(a year old)...no vac leaks. Can't figure it out...
