O.K. I've replaced: Distributor O2 Sensor Idle Air Control Valve Fuel Filter Fuel Pump Main Relay Everything that I replaced is brand new, and I pretty much needed to replace most of it, besides the fuel pump, but hey, now I got a better one. The problem: The car idles pretty much just fine, occasionally dies. When I'm driving it and start to accelerate harder the tach will bounce, and the engine will sputter and buck a little, like it's not getting something of what it needs. I'm completely stumped now, and on monday I'm taking it to a mechanic to run some diagnostics on it, to figure out the problem. What's weird though, is that right after I replaced the fuel filter, it stopped having the problem...for a week. Then the problem came right back. So the damn mechanic better be able to figure out what the problem is. If anyone else can thing of something, let me know.
