    High idle. Engine won't slow down while coasting. No HVAC controls. P1506. Related?

    One more thing I forgot to mention. Regardless of setting, the ac/heater still has a little bit of air coming out at the floor. So I think I may have a small leak somewhere, but I think it's going to be pretty tough to find.

    So I was searching for vacuum leaks (for what seems like the thirtieth time) and while I was standing there with the hood open I had a thought... I decided to completely back out the idle adjustment screw. I then went and drove it and it was a LOT better. Before I would put it in neutral and...

    I installed a new (old) vacuum reservoir today. The good news is that I now have full heating and cooling functionality. The bad news is that the check engine light came right back on and the motor still behaves exactly as before. In the morning I'm going to give the engine bay another once...

    I'm referring to the cut lines that are plugged with screws that I posted pictures of a couple days ago. I'm pretty sure they go to the missing HVAC orb. I'm going to the junkyard in the morning to try and buy one, as well as see how it's supposed to be hooked up. I've been trying to check...

    So, I reset the CEL light and replaced three hoses that were cracked/in bad shape. I replaced the one that goes from the valve cover to the throttle body. And also the two that are connected to this thing... Sorry, I'm not sure what it's called. It seemed to run a little better, but after...

    Well the check engine light came back on, so I swapped the old IAC back in. Hopefully Auto Zone will let me return the one I bought. But, I did find something interesting... The white one connects to a black one then appears to go up under the dash. The black one connects to a red one then...

    I reset the CEL with my Ultragauge, and then replaced the IAC valve. The check engine light is still off, but I only drove it about four miles after. The idle has gone up even higher. Now it sits around 1050. Other than that, no change.

    I swear I had read somewhere that they were about $100. Which is why I've been hesitant. But I just checked auto zone and they're only 39. Much more reasonable. And, there is a 24HR auto zone three miles from me. I'll report back in an hour.

    I have a 98 2WD ford ranger with a 2.5L. I bought it a little over a month ago and I noticed shortly after that it was idling a little high. It seems like it's gotten a bit worse and now it idles at about 925-975 RPM. Its not a perfectly smooth idle, but it isn't too rough. The motor...
