My problem is that the vacuum on the left side of the picture is not plugged in. As I tried to plug it the correct way, as posted above, my car would die whenever I shifted. It would idle fine at P and N, but D would kill it. I know it has something to do with my cam, and hopefully it can be fixed. I need to know how to adjust my idle so I can fix this. I really think this is the whole reason why my car smells like gas fumes all the time.

I don't know a "real" fix but you might try turning up the idle screw that goes against your throttle body blade arm as a temporary fix. It might provide you enough "catch" for the computer to keep you idling...until you get the "real" problem fixed.

Where are you idling at anyways?

Nice to hear from you again.

I'm idling at about 800. I just played with it a little while ago and it managed to stay on but it still did it after a couple of shifts. Someone had told me that adjusting your idle wasn't that easy. Something about some sensors or something like that. Also, will it affect performance or anything if I just leave it like that?

Ooppsss...sorry I was late. Yeah the idle motor is the IAC (the cylinder looking deal on the side of your TB)...

I know your computer is more sensitive than my computer and I just now that I was having a similar issue and I just had to bump my idle up a bit and I had no more "dies".

Probably the sensor talked about is the TPS (throttle position sensor). This is the link for that one: http://www.muscularmustangs.com/tps.php

I have mine set at .985 right now...I didn't notice any noticeable difference between it and my previous setting of 1.106v...

No problem on the late reaction. I just decided to leave as is. Do you know if it'll affect performance? Air/Fuel Mixture?

If your anywhere within .95 to 1.1V reading for the TPS you'll be just fine...

The IAC isn't really going to effect your actual "horsepower" performance but when I cleaned mine out mine did idle better. I sprayed it out with lots of carb cleaner and used some q-tips to get more "specific" with the cleaning and let it air dry. A very simple job that let my car idle after I first started it up instead of it wanting to die on me.

The TPS and IAC aren't going to effect your air/fuel mixture...

Good Luck...

Thanks man. I cleaned both of them not too long ago. I'll just check my volts to make sure everything is ok and leave it as is.
