Hey all. I need help yet again and this message board has always been the place to go for answers. Great site, great people.
Ok. I want to know how to troubleshoot this problem. Any help would be greatly appreciated. When I start my car in the morning or when its been sitting for a couple of hours and I start it, everything seems ok. Even if I rev up the engine, I have no problems. When I drive the car everything seems ok. After a couple of minutes though, the engine begins to sputter horribly and I lose acceleration, so I have to pull over. At this point the engine idles perfect, but I just can't accelerate If I let it idle for about 20 seconds, I can drive away and for the rest of the day have no problems at all. The engine never shuts off during any of this. Could this be my Computer? Mass air? Injectors? Fuel filter? Fuel relay? EGR? XCS? POS? MOM? DAD? I have no idea where to begin. Thanks.

could it possibly be some faulty readings coming from the o2 sensors as the temp is climbing on them. Maybe a intermitent fault with the heat. Clean the wire on the MASS Air unit with a good greasless electronics cleaner and try to get a scan tool and look for stored codes.

its the fuel filter or the sock in the tank.

Thanks. I'll clean the mass air and change the fuel filter. Any idea on how to clean the o2 sensors? Thanks.
