The IAC rarely causes a high idle situation. Usually, the needle valve inside gets stuck closed and caused the engine to die upon start up, or the IAC solenoid just goes bad and fails shut.

I get a little frustrated myself when people say things like "frustrated, I took the car to the dealership" or "as a last resort" type thing. But in this case, it looks like you got some bad advice. I've rarely seen a MAF cause driveability problems like the ones you describe. As a matter of fact, MAF's hardly ever go bad, but there are SOME techs out there that replace them "religiously" for anything.

I wouldn't have been so quick to replace that O2 sensor. You should have put the old MAF back on first. Also, you CAN'T JUST swap out MAF'S for bigger ones. They have to be calibrated for your car....you didn't mention that.

After all of this, I really can't help you out because like I said in the first sentence, you're really not clear on which symptom you're after. You're right that there are two different O2 sensors, one is a monitor, the other is the heater. The one you're after is the one with a green connector. The other ones have a blue connector.

How many miles are on your car? Is your throttle body clean or is it sticking with carbon and oil build up. This is a common occurence with high mileage cars and could cause your high idle. Do you have any hi performance mods? If so, then anything could be causing the driveability concern.

Don't think I helped, but maybe gave you a couple of things to think about.

Dave

Don't think I can help you out on the vibration as, like any other decent mechanic, I'd have to experience it first hand, and I haven't seen or worked on any other 4.6 dohc cars with that concern. Kind of hard taking a stab in the dark. It's hard to tell if anything you did to the car caused it, but I wouldn't think new 02 sensors would do that as they really don't do anything other than sit there and "sniff". It doesn't sound like you've got a base engine concern, so it's hard to tell. The vibration in my '03 Mach has been there since I bought it, so I chalked that up as a "normal vehicle characteristic".

Do me a favor, and either put your VIN in your next post here or email it to me and I'll run an OASIS report for you and see if there's anything out there that's been reported concerning your complaint. I'm home all day just farting around with Christmas lights and what not, so I can check here frequently.

P.S. At $150 a pop, I'd be a little apprehensive at the dealerships as well, especially after hearing the inconclusive diagnosis they sold you (MAF sensor). Here in Kansas City, we charge $79 for an EEC diagnosis. I think that's a pretty good price and worth it. There are some shops that charge over $100, so sometimes it pays to shop around. Of course, it's all relative because no matter if you pay $79, $100, or $150, your money buys you only what that particular dealership has to offer you in technician. I feel I'm a pretty decent drive tech, so for the $79 we charge, the customer is getting a pretty good deal. Food for thought, and I may be blowing a little smoke up my own butt, but if I didn't believe in myself then I wouldn't feel so comfortable with my job and enjoy it so much.

SPECIAL SERVICE MESSAGES
15697 NORMAL CONDITION: MOMENTARY GRUNTING SOUND
SOME VEHICLES WITH AIR CONDITIONING UTILIZING R-134A MAY EXHIBIT A MOMENTARY GRUNT/POP AFTER BEING PARKED FOR SOME TIME & THE COMPRESSOR IS ENGAGED BEFORE THE ENGINE COMPARTMENT HAS WARMED UP. THIS IS DUE TO LIQUID R134A BEING PUMPED OUT OF THE COMPRESSOR. R134A WILL TRAVEL TO THE COOLEST POINT (THE COMPRESSOR) ONCE THE ENGINE HAS COOLED, DUE TO THE DIFFERENCE IN TEMP BETWEEN THE ENGINE COMPARTMENT & THE VEHICLE INTERIOR. WHILE MANY VEHICLES HAVE PCM STRATEGIES THAT ADDRESS THIS BY REPEATEDLY CYCLING THE COMPRESSOR ON START- UP, THIS MAY NOT TOTALLY ELIMINATE IT. REPLACING A/C COMPONENTS WILL NOT ELIMINATE THIS. COMPONENT DURABILITY IS NOT AFFECTED. MINIMIZE THE NOISE BY TURNING THE A/C SYSTEM TO VENT BEFORE EXITING, & IN MILD AMBIENT TEMPS (APPROX. 50-75F) WAITING A FEW MINUTES BEFORE TURNING ON THE A/C OR DEFROST.
