My 1997 dodge v10 runs ok right after it is started but once it warms up it starts cutting out and has no power but once above 3 thousand rpm it seems to smooth out. Any ideas on whats going on?

 

Do the V10s also have plenum issues?

 

Not like the V8 Magnum engines.

OP, CEL on? Any stored codes?

How many miles on the truck?

O2 sensors original?

 

200,000 on truck just bought the pickup and swapped engine over into half ton, believe there are original o2 sensors but not sure. The codes its showing is
p0743 torque converter circuit electrical
P0753 shift solenoid a circuit
Po713 trans fluid temp sensor high input
P1763 gov press sensor hi
Which are all tranny related, would the trans be causing it to run like this?

 

But no misfire codes...... I would check fuel pressure.

 

Unhooked o2 sensors and drove it for awhile, it still cuts out but the problem seems to come and go, somtimes it will sputter during acceleration somtimes it acts fine, but it always falls on its face if you just smash it to the floor. I know i need to check fuel pressure but dont have a guage at the moment, im working on barrowing one

 

Parts store will rent you one.

 

So a V10 into a 1500, Ok what pcm did you use? What year is the motor and what year is the truck? I know you posted 97, but both years would be a help.

 

The engine was doing this in its original pickup, i suspected it as rotten gas because it had set so long but after i swapped it i used the fuel tank from the other pickup. The engine still has the problem after using a different fuel tank and pump. im using the comple engine harness, enginebay harness and cab harness, also the computer that came with the 97 v10. the 1500 is a 94

 

Where im from our parts stores arent big enough to rent out tools, its over an hour to a walmart, our parts stores are privately owned
