curiousity

has anybody else had this happen? Yesterday (Sat) truck acted like it would not get out of its own way (sunny and mid to upper fifties). but today after sunset mid to upper forties, truck runs like a scalded dog. Did nothing to it from incident to incident, cept park her. Recently had a new gas station open up and has gas for $2.87 a gal causing the others in the same area to drop from 2.99 to "compete". The way she was acting Sat I was thinking poor fuel Sun however, she acted like she was drinking aviation fuel - still had an audible "ping" but run, man she was a screamer. any thoughts.

Mine likes to do that, I have no idea why. Sometimes it gets up and moves other times it drags it butt everywhere.

Have you tried any kind of diagnostic to try and determine "wtf"????????

Man you have no idea, the only thing I have never done is actually pull the fuel pump out to look at the filter sock. I had a well known tranny guy drive it because I suspected the torque converter but he said everything seemed like it was working fine but to suspect fuel issues. I had already changed the fuel filter so I checked the pressure at the rail and it was fine, compression is fine, fresh tune up, tranny fluid is fresh, tps is new, I de-carboned the intake, I run injector cleaner every oil change and I run 5-30 full synthetic. I cannot find anything wrong its impossible to figure it out because its so random. I have done a bunch of other stuff that is to long to list this truck has been a pain.
