When I start the engine it idles fine to begin with. I put it in gear and start driving, and by the time I get to the end of the street it has been stalling. I start it again, and it idles low and rough. When I give it the gas it hesitates badly.
I have replaced the IACV, TPS, ignition coil, cap, and rotor. A couple of months ago I rebuilt the TBI (including new fuel pressure regulator). I removed the EGR valve to examine for carbon buildup in the manifold passages beneath it and they were clear. The EGR valve itself has been replaced within the past few years. The coolant temp sensor on top of the manifold next to the water inlet is also fairly new at around six months old.
