Yesterday (Tuesday) I drove the truck for the first time since arriving in Phoenix. The check engine light kicked on and stayed on the entire time I drove the truck. At stop lights the truck would go from idling as if the engine wasnt even running (which is great) to choking every 10 seconds or so. The choking made it feel like the truck was going stall. It had me in a panic everytime I came up to a light.
So, I stopped by O'Reilleys and had them check for a code. It said it was an issue related to the catalytic converter. I took the truck in to a muffler shop and they installed two new cats. The one cat was completely wasted inside and definitely needed to be replaced. After an hours wait. Voila. Two new cats and I was back on the road. I thought my problems were resolved! NOPE! Read on.
Once again the truck acted as if it wanted to stall at lights! Then as I was exiting the freeway, the truck decided to stall completely as I pulled up to the light. I couldnt restart the truck so I exited the truck and gave it 5 minutes. I went back to the truck and started it up. I drove straight to an Auto Zone. I spoke with one of the guys and described my problem. He said it could be a fuel filter, fuel pump, a sensor, a vacuum issue, etc. I purchased a fuel filter and I am going to start with that. While I am in there I am going to check the spark plugs as well.
Does anyone have any other suggestions or recommendations? Thank you for your help!
