Many problems started close together…. Oil pressure stays fairly low, driving down the highway sudden loss of power went into limp mode only able to get it out by clearing the code with the scan tool and had to do this repeatedly, fuel pressure low, it starts cutting out and back firing around 1/4 tank of gas, lately it’s been idling high and it will return to regular rpm’s if I turn the steering wheel all the way to the left , it will slightly stack and cut out while driving especially upon taking off if the gas pedal is pressed to far and have to ease into little acceleration at a time but not staying on the pedal constantly because it’ll start back firing and won’t go so have to pump it easily and then it will regulate and can drive overall like normal. It’s been getting 9 miles per gallon
