My 2003 Pontiac Aztek has approximately 130,000. Over the last year I have replaced the fuel pump and wiring harness. Was running fine until the other morning I started it and it was idling extremely high. I added a bottle of fuel injector/carb cleaner to the gas tank and it helped for a couple of days. The idle problem has come back and now the vehicle is not accelerating properly. Just today, my car died when at a stop light. It started right back up, but the high idle and acceleration problem were still there. Any help would be greatly appreciated.
