i just bought a 1991 jeep wrangler, 4.0 L, 6 cylinder.

it has new:
Fuel Pump
Fuel Filter
Plugs
wires
Coil
throttle position sensor
oxygen sensor
and auto idle moter

there is a slight oil flow in #1...
it wont idle, it dies when clutch is let out (orput in gear), there is some backfiring before it dies.

the code reads 33, which means an A/C problem according to the guys at auto zone. the only problem with that is that there is no A/C in it.. so i am kinda lost.

does anyone know what could be wrong with it?

Code 33 is just telling you that there is no relay switch/fuse in the power box under the hood for the A/C. This is 100% normal since you don't have A/C. The problem must lie somewhere else. Check your fuel pressure and Crank position sensor.

ya, code 33 is nothing.

i'm concerned about oil in #1, how did you determine this? cuz that is a big problem. and backfiring could be an indication the timing is off.

are you sure the firing order is right, maybe backfiring is just bad misfiring. and i didn't see cap and rotor on the tune up list, those can't be ignored.
