Hey Scott, I hope everything is going good. I have a 2016 Dodge Challenger sxt and lately I’ve been having this problem that after I drive for about 2 hours my engine starts idling. I’ve taking it to multiple mechanics and no one knows what’s going on. At first it runs perfectly but after a while it idles to the point where I can’t drive it anymore for the day. One time I got a check engine light so I took it to autozone and 3 codes came out which was the map sensor, which was replaced, a p0171 and p0174 codes but still not running properly after a while. I hope you can help me fix this. Thanks and have a great day!
Your vehicle is currently running too lean-not enough fuel and too much air.
I would start by checking the fuel pump, fuel filter(could be clogged) and fuel injectors (could be clogged). Check your fuel pressure as well. See if you have any air leaks.
What should I look for? Anything specific to let me know if it’s the fuel pump or the others?
