guy i work with has an 01 model 2500 with the 8.1L in it. when your are cruising at 55-60mph it is fine but if you stomp on it to pass or whatnot the thing just dies. cam sensor was replaced about 1000 miles ago but this problem just started. also, when this started, the cruise control he says is not functioning at all, not even the indicator light on the dash comes on. any ideas?

 

anyone?????

 

we have an 8.1 in a KODIAK work truck that thing is a POS it has lo miles and it is always F'n up

 

anyone else???

 

LMAO!! Glad you like your Big block.

Anyway, maybe a PCM failure if your gettin no codes.

 

Fuel. Look at the pump. When was the filter changed last?
