I need help figuring out whats wrong with my truck. I have a 1994 Dodge ram 1500 3.9L v6 Magnum

I have tried to use the flash method & these are the 3 codes i recieve:

33
52
55

The truck started sputtering & sounds like a misfire or pop from the throttle body & it seems like a lot of hesitation, what i mean is i push on the gas and it dont seem like the truck has it's full power.

Sometimes it runs fine on narrow roads but if i bring it on the highway where it is much wider open area it'll sputter right away & lose power & misfire (pop from under hood)

I have recently changed the oil (which smelt like gas a little bit) & plugs.

Any suggestions to my problem?

 

33 Short or open in the AC clutch circuit.

I doubt this is a contributor.

52 O2 sensor signal indicates rich air/fuel ratio during engine operation.

If your truck has close to, or over, 100K miles, replace the O2 sensor.

55 End of messages.

Read the plenum sticky at the top of this forum as well. Chances are good, that is a major contributor to the failed O2 sensor.
