96 2.3 uppermanifold backfire?
I have a 1996 Ranger 2.3L, 5 speed manual, AC, power steering. When you crack the throttle it bogs, sucks air, and pops out the throttle body. Really bad with A/C on. I have almost 20 hg constant vaccum at idle. No check engine light. I'm only getting 20 mpg. Will removing the octance timing module (retards 2 degrees) help? It also will idle high after trips with or without the A/C on. That is intermitent. The backfire is constant. If you feather in the throttle it won't do it but it has poor throttle response.

How many miles are on the truck?
The IAC is the idle air control valve, controls idle speed, normally located on/near throttle body. There might be a picture of one in the links I have in the tech info thread.

If it ran fine at one point then I wouldn't "fix" the problem by removing the octane plug.
I'm wondering if you jumped a tooth on the timing belt, does anyone else have a thought about this idea.
I would still pull the codes, just to make sure nothing is there.
