Motorcraft CX1946 Idle Air Control Motor

My Ford Ranger was idling incredibly rough and occasionally stalling at stoplights. I tried cleaning the old valve, but it didn't help. I decided to spend the extra bit for the Motorcraft CX1946 rather than a cheap knock-off, and it was worth every penny. It was a direct fit, took 10 minutes to install, and the truck is back to idling smoothly. Don't waste your time with aftermarket brands; stick with OEM for this part.

My 2002 Ranger has experienced throttle issues for the last few months. I've tried several auto parts store brand replacements. None of them fixed my issue. I decided to give this OEM part a try and it resolved all the issues that the parts store house brands couldn't. I'll update this review if I have any issues. Otherwise, it was a great purchase!

This part is a choice replacement for Idle Air Control on 2003 Ford Taurus with 637,753 miles. Original part lasted for most of this run-time. On hot days with multiple short trips, engine wouldn't idle at startup. Had to cool the part and clean carbon from the valve to start and idle the engine. Aftermarket part from Napa was okay for a short time, but produced high idle at startup (cold or hot engine), surge and high idle with vehicle stopped (closed throttle) after a long drive on a hot day. Fuel economy was also less with the aftermarket part. This new OEM part restored reliable start and idle on hot days, improved fuel economy and restored smooth shifts and downshifts. Note this vehicle consistently gets 23-25 mpg in combined freeway, mountain, and city driving with 500 miles/week commuting and errands. I've used Motorcraft synthetic blend 5W-20 and 5W-30 oil with 3000-5000 mile change intervals, for my tour of ownership starting at about 51,700 miles.

Yeah sure, I also bought the Motorcraft Ford brand because of bad reviews on the other Chinese brands. But geeze..... they couldn't include a gasket that couldn't cost more than 5-10 cents?

After trying to aftermarket product this product stood up to what supposed to be worked perfectly brought my RPMs from dipping no popping noise like the new no name brand I installed. Great product I recommended.

Worked perfectly

Part installed on 2003 Ford Ranger Edge, 3.0 flex fuel engine, 2WD. Had issue where engine rpms dropped at idle once A/C cycled on, thereby telling ECM to shut off A/C compressor to prevent an engine stall issue. Replacing this cleared up that issue. I had previously purchased non-OEM IAC's, but returned because connector orientation was so far off, my wiring harness wouldn't reach. Not a lot of slack with that. This had same issue, but not to the extent of the others. OEM AIC connector was at the 6 o'clock position. Part I received had it at 3 o'clock. Wiring harness connected reached - just had to run the wires to the inside of the throttle position senson (sits below this part) rather than over the outside like it was before. Would have preferred an exact match, but at least it works.

First off this will fit a Ranger 3.0 gas engine although Amazon said it would not. My idle was up and down stalling at stop lights and then my engine light came on. After some online research I found this Idle air control to be the most common problem, after installing it the engine seemed to idle better but not perfect I figured that the computer will probably have to relearn idle settings with this new part. The engine light stayed on for about 2 days then turned off and the idling seems to be normal now.

Very happy with this unit. I was experiencing a high idle and high rpm between shifts on my 2003 Ford Ranger. This unit resolved these issues. Note: after installing the new unit, I found I had to unplug the battery to reset the computer before I noticed a difference.

replaced the iacv with a junkyard part from another ford taurus. Still had the same erratic idle issues at idle once the car warmed up. Finally caved and bought this one from amazon. Installed, cleared the codes by disconnecting the battery. now the car runs smooth as ever.

I installed on 2002 ford taurus se sedan 3.0l OHV , and engine starts right away , Response in idle and acceleration are good seems there is more torque in total , i Recommend .

Bought for ranger. 2.3 litre. Doesn't fit. Waste of money.
