Hey all. I can't believe that I just typed a message that took me about twenty minutes to type and it was erased because I didn't type my right screen name and when I hit my back button everything I just typed was gone! That royally sucks *** ! Here goes again. I recently posted a problem about my car stuttering and I still havn't fixed it. Maybe someone can help. Heres the scenario.
When I start my car, cold or warm, a few minutes after driving it, It begins to stutter/pop under part throttle and I loose acceration, resulting in having to pull over unless I smash the pedal to WOT and it accelerates hard without a problem. If I pull over and wait a couple of minutes I can drive away just fine and the car runs fine until I turn off the engine and let it sit for a couple of minutes. During all of this the engine idles perfect, even if the stuttering problem occurs I can let off the gas and the engine idles ok. This is a problem that only happens at part throttle, when it happens. I've changed the plugs, cap/rotor, fuel filter, checked for pinched fuel lines, I have a fuel pressure regulator and it doesn't drop in pessure. All vacuum lines are attached. I even disconnected the EGR and Idle Air Bypass Valve and same problem. I had this problem once last year for one day and then it went away. I thought it was water in the gas tank from the heavy rains here in Miami. I need help, please. Thanks.
