Chevy S10 Sputters on the Highway. Feels like it someone is tapping the brakes,...
...and I THINK I heard misfire.? The S10 sputters on the Hwy around 55+, I tried to go as fast as 85 and it didnt go away so I slowed down to 70, which gets you ran off the road on the FL turnpike.
-Check Engine Light came on w/ 3 codes: Weak signal from TPS sensor, EGR valve, weak signal from Fuel Pump
-I bought a new fuel pump assembly and it didnt help at all
-Truck idles, and drives around town perfectly
-Started a couple of days ago on the way down to Miami, didnt stop on the way back to Orlando
-Craziest part, I tailgated (almost at a dangerous level) with a semi truck for an hour and it drove perfectly, AS SOON as the semi exited and I was left alone the problem came right back
I dont want to guess and spend money on parts I dont need, especially since I already bought and installed a fuel pump.
I REALLY think it is a wiring/bad wire problem. What else could it be, or how do I find a bad wire. Where should I start looking???
This thing has me flat out stumped...
BTW, S10 for sale LOL
