Yesterday I got it to run again.
It happens like this,

I turn on the Ram.
let it idle in P (If I rev it it starts to bog and misfire BAD)
Shift it to N, extra ****ty idle, almost dying (rev it and its FINE!- no misfires)
shift it to D and start peeling the tires (this is the only way I can get it to work)
Shift it to R and do the same thing.
Now I can drive it around with no problems.
If im on a red light for a while, it'll stall

 

bump.

 

Any codes?

 

I haven't scanned it recently.
could it be lack of transmission oil?
crankshaft pos sens?

 

It makes me wonder why it'll work after a couple of minutes driving it.
anyone? Im stuck and really need this truck runing. The help
would be very much appreciated

 

I would get the FSM out and see what sensors are used in open loop warm up and start trouble shooting each one.

After warm up, the PCM uses the O2 sensor to help determine fuel needs. Id start by checking all sensors relating to fuel and air metering, if you've ruled out spark production.

Id also have the battery checked just to rule it out.

 

the Crank Position Sensor was the culprit.
Changed it and now it purrs like a tiger.
The old sensor seemed to be scratched

 

It seems im still not done with this truck :P
Another push rod went through the rocker arm. I
am now gonna change all the rocker arms push rods and lifters.
I have removed the Intake manifold and valve covers

 

Get some Harland Sharp 1.7 roller rockers.

 

Pushrods go thru rockers for one reason, and one reason only. Lack of lubrication.
