New to the Dodge world
Ok first of this will probally be a long post.
I have been banging my head trying to figure out a problem. since i got this truck a few days ago.
I have a 98 ram 1500 SLT Laramie 4x4 with 318.
After about 30 seconds after start up the idle goes up and down between 400 and 800.
I can rev it to the moon if i want and it is smooth when cold.
It drives good for the first couple minutes also when it was cold. Once it gets warm it starts to pop and kinda like back fire thru the exhaust and i have very little power.......i can put my foot down and it will downshift then take off but still a little rough. Once i let of it is back to popping and back fire. Even at this point i can put it in neutral and rev it just fine ( maybe small popping as it comes back down in rpm's )
Okay now what i have done all ready.
New plugs (stock champion)
New wires (autolite)
New cap and rotor
I routed the wires per the tsb
I cleaned the IAC
Check that the TPS is working correct.
Removed the TB and cleaned totally. New gasket.
New upstream 02 sensor
Cat converter was gutted allready.
I found 1 broken vacuum line and fixed that. I haven't gone thru all the vacuums yet to look for leaks.
What am i missing? Would the plenum problem cause this?
PLEASE HELP ME BEFORE I SHOOT THIS THING AND FIND ANOTHER CHEVY TRUCK.

would this be good enough to test the fuel pressure?

Bosch O2 sensors suck, and our trucks don't like 'em. NTK or Denso are the brands that are preferred.

NTK or DENSO brands can be got online at Rock Auto. I never looked at local parts stores though (e.g., autozone, oreillys, napa, etc.).
