Acts fuel starved (intermittent) when warmed up. In 2 to 3 weeks time, car has stalled at idle (3 different times), and would crank normally but not start 5 different times. In all cases car was warmed up. Switched fuel pump relay w rear fog relay and started 5 times - no problem. Yesterday, went to work ( half-hour, in traffic) no problem. Stalled in fast food line, at idle. Went back later- started. Help!

Hello -

Please go to Auto Zone (AZ) or O'Reilly's (OR) and for FREE they can pull the codes to the car. Most important: Once they check your codes, if they find something and you don't get it fixed and need to get back with us, please make sure you tell us exactly what the code was, number and all. Example, if the code was E0568 O2 Sensor bad. Then make sure you give us all of that. While there for FREE also they can bring their tester out and check your battery and alternator.

We need to figure out if it is electrical or fuel related. Pull a plug wire off of the spark plug and insert something into the end of it and have someone try to start the car and have the metal object really close to a piece of metal on the engine and see if you are getting a good strong popping blue spark. Don't have your hands on any part of the metal! If there is no spark, then it is electrical.

If you are getting good spark then spray some starting fluid in the throttle body and try to start it and see if it tries to start then.

Hello -

Also, it looks like you may have some recalls on your vehicle. The dealer may fix these for free. Please contact the dealer service department, give them the VIN number of your car and have them check on these to see if they apply to you.
