Engine Mechanical problem
1997 GMC Truck V8 Four Wheel Drive Automatic
I just put a new 5.7 engine in my truck.
It runs great when cool but as it gets warm will start a slight sputter and die when approaching stop lights,signs,etc.
When it does this it is throwing a check engine light that is never on when it is cool and running good.It will start back but you have to hold it to the floor and it will sound like you pulled off a few plug wires(pop,pop,pop pop) and sometimes will smooth out but not always. When it cools back down it starts and runs fine again.
I have replaced the spider injection,crank position sensor,and plugs.
Can a CONTROL MODULE cause this?
I cant get it anywhere to check the codes for awhile but my father in law owns a salvage yard where getting parts to swap are fairly easy .
Thought there might be a couple "common" causes. Thanks, Rod Hipsher
