Asked by Nov 20, 2014 at 08:25 PM about the 2003 Chevrolet Tahoe LT 4WD

Question type: Maintenance & Repair

I changed the alternator, bought a new battery, changed the oil and it's still cutting off
when I stop at a light or try to slow down and turn. Any suggestions?

Ok so it will crank and stay crunk, but soon as I put it in reverse or drive, it shuts off.

Check the throttle position sensor,and make sure there are no vacume leak,s around intake,may not hurt to clean throttle plate all so.

"Throttle position sensor, throttle plate(butterfly) if it's dirty clean it with carb cleaner, fuel pressure regulator. When is the last time it had spark plugs and wires put on? They those things if you already got a new battery and alternator." @TransAm77, Well go from here. I had them changed in late February, I'll try all other options and let you all know. Thanks so much!
