Having an issue with my truck, I've always got some sound mechanical advice from you guys so maybe we have a shot of hope here. I'm getting no luck on dedicated forums. Delete if not allowed
I have a 2005 4.2L F150 with 257xxx. 2 weeks ago I filled the truck up with fuel and the auto shutoff on the pump didn’t work, so it slightly overflowed and was filled to the brim of the filler neck. After turning the truck on I noticed the check engine light was on, but ran fine. Last week I was waiting in a drive through, it was taking a while so I had the truck in park. I felt it start to idle rough so I turned my music and AC off to get a better idea, The truck started to develop a pretty nasty surge where it sounded like it was on the cusp of quitting a couple times, I put it in drive to get out of the way and it was very sluggish when I lightly accelerated, almost like a carburetor with junk in the jets, it eventually ramped itself up and I parked in an empty spot. The truck idled rough for a few more seconds and then returned to its normal state.
Did it again on the way home last night, saw the light turned red up the road so I let off the throttle and lightly started braking, I felt the engine idling rough again and as I came to a stop it did the same thing as last time, when the light turned green I lightly eased onto the throttle and it had its “hiccups” again until it got itself up to speed and got me home.
This morning I stopped by a buddies shop and used his scanner where I pulled P0191 and P0193 (Fuel range pressure performance and Fuel rail pressure high input). I cleared the codes, drove to school, and was idling for about 3 minutes until it started its surge again, but this time I had no code pop up. I have a spare fuel filter and cap at home that I plan on replacing tonight to see if it will help at all, but I’m not feeling very confident about it. I'm leaning towards the fuel rail pressure sensor since the tank was overfilled and might've stressed the sensor.
