Had a CEL- P0132, I changed the pre cat O2 sensor. CEL came on again, P0132 & P0138. Change the other O2 sensor. Reset the PCM by disconnecting the positive cable....... Now CEL still on and every so often, the truck starts cutting out. Sitting at a stop light, the rpms get down to 500, it feels like it is going to stall. When I take off, it still cuts out. Then all of a sudden it goes away. There is no telling when it is going to do it again, there is no consistency to this problem.
Any thoughts?

 

what year and engine size and drivetrain would help, i know on the 5.2/5.9 engines the IAC valve tends to get dirty and cause problems

 

Its a 1999 5.2 4 x 4. The IAC is the plunger on the back of the throttle body, correct? Would spraying with carb cleaner do the trick?

 

umm yea if you take the air hat off its on the back of the throttle body against the firewall, and i would just take it out and replace it, its not expensive, but if you have no money just take it out and soak it in carb cleaner than move it in and out a little so clean it all, put it back in , you will need to step on the gas to start it the first time after taking it out, and it will dy as soon as you let off, but after that it should be fine, that fixed a similar problem on my old dakota
