ive replace the IACV
when i replaced the air control sensor it seemed to help.

Could the timing be off?

Try Craigslist or a salvage yard. I got my tranny from a wrecked ranger.

I had a similar issue and ended up being the Air Charge Temp Sensor, about $20, on the passenger side of the upper intake manifold. Sensor was telling the engine it was below zero outside and the engine was guzzling gas to compensate, which also caused it to stutter and stall out when I first start...

If the smell of gas is over powering, it is not a fuel problem. i am willing to bet that the exhaust is plugged. what state are you in and does it still have a cat on it. sorry. cat is catalytic converter I just got a new one put in( flo master ) like 4 months ago. I'm in California. I feel like wh...

So what happens is I turn my car on and then it sounds normal then the rpms drop and the car starts to shake and then powers off, it will stay on if I press the gas though. I dont know if the timing might be off, i would like some guidance on how to fix it if its the timing. I read somewhere you hav...

Ok how do I do that. I know some about cars but not much. A guide would be appreciated.

That sounds pretty close to what that Air Charge Temp Sensor was doing for me. I was trying to pass smog and was told the BII was running crazy rich, basically guzzling gas like you're saying. My fluctuating idle would usually go away after it warmed up though. Anyways, for $20, it might be worth a...

Yea, it's not the thermostat that I replaced. It was called Air Charge Temp Sensor. About $20 and located on the upper intake manifold. I'm guessing it's not brake booster because you said it idles up and down when driving around. Ya might have to go get it diagnosed. I hope I get an answer. It chu...

Doesn't sound like an oxygen sensor issue....but it's located passenger side exhaust pipe, just upstream from the cat....probably easier to see from the bottom side. My BII had an issue where it didn't want to hold idle and would stall out until it got warm. I replaced IACV too with no luck. Turned...

Where are they located. My bronco starts up but then starts to low idle at 400,300,200,100 then back to 400. And does that when driving around. I've replace idle controll thing. I think it's the oxygen sensors.
