Hesitation when accelerating
I have a 2004 Dodge Durango 4.7 liter all wheel and 4 wheel drive it’s had many new parts prior to me purchasing the parts replaced are crank position sensor, idle air control valve, fuel pump (rebuilt), wiring harnesses, used throttle position sensor. The coils and spark plugs look great air filter changed. The codes that were coming up were crank position sensor, cylinder misfire, EVAP system leak got a new gas cap old one was not sealing off. It’s not stalling like it was but when I accelerate it hesitates really bad like it’s not getting gas then drops out but when I pump the gas it’s fine but I cannot accelerate to fast or I have this issue. I’m thinking it could be the MAP sensor? I have ran treatment through the system for the injectors and fuel I have cleaned the intake so i could use a little assistance on what this could be. It’s my only vehicle and I love this truck but I need it to run right it hasn’t since I got it but it’s getting better 😊
thanks in advance

I am not sure exactly what crank position sensor it was bought before I got the truck but it was purchased at Auto Zone. I did clear the codes the check engine light came back on and I’ll have to check the codes again and see if something different appears. Thanks for the reply I greatly appreciate it. From what I am reading though it seems to be somewhere in the fuel system at this point is what I am guessing. Ugh what a hassle but with everything that has been done to it recently it’s tunn a whole lot better 😁
If you have coil packs, trace down which ones are bad and replace. Get Gummout Multi purpose cleaner. It looks like Seafoam but, works much better. Throw half the can in the gas tank with at least a half of tank of gas. That will clean your fuel injectors. You also might want to replace the gas filter. Get a spray bottle with water, start the car, pop the hood, while the car is idling, spray around the intake hoses and connections to see if you have a vacuum leak. If the idle surges while you're spraying the intake hoses, then you have a vacuum leak, which can cause the P0300.
