Ok, it feels like an old carb engine that has water in the gas. Dropped the tank and cleaned it, no water. Removed the fuel rail, no water. Only does it from a stop and under heavy accl up hills and passing. It does not turn on the ses light but strangely it does turn on the low tire light.

 

What are you driving? Engine? Trans? Mileage? Last tune-up?

 

2011, 1500, 4x4, 5.7 6sp auto, 265685, tune-up done with cam/lifter repair, heads done at same time just because they were off. Had the fuel tank recall done this spring and that's when I started to feel it slightly. Steadily getting worse.

 

Fuel line restricted somewhere?

 

Fuel pump could be weak. Don't get aftermarket pump if that's the direction you go.

 

Well, not the pump or restriction. Didn't do it for a week then yesterday it started doing it again. It's not turning the ses light on but the low tire light will flash when it does it. Almost feels like the MDI system is acting up but that should set the ses light. Local dealer scanned it, said no codes set (duh). Suggested I replace the engine due to the 288k miles because it's worn out. Gave me a price around $8000.00 for a reman installed. Told them KMA it's an electrical issue, not mechanical.

 

Next time it acts up try to get the codes from somewhere besides the dealer.

 

Still not setting codes. Decided to load up the parts cannon and start firing. Replaced coils and plugs. Hasn't done it for a week so far. Still trying to figure out why it would turn on the low tire light and not the ses light.
