Are you getting any codes from the fuel injection computer? It's located under the dash - drivers side kick panel. There is an LED that will flash you the codes. Connect the two green connectors under the hood by the wiper motor near the firewall on the drivers side - this will get you into "test mode" and flash the codes through the computer.


Perhaps your coolant temp sensor is on the way out - or your MAF may need cleaning/replacing. Both fairly common. See what the computer says first.
