DIY How to clean the IAC - Page 2

Thats exactly what I did about a month ago (I actually took the entire throttle body off and cleaned it, too). Mine was WAY worse than the one in your pictures, though. I had noticed the random high/low idling since I got this van, when I took it to get checked out for goofing up (bad ECM) they suggested cleaning the throttle body.

Excellent job on the walk-through for cleaning it!

BlueVanACD2005,

I'm really glad that this is helping many of the Dodge Ram Van/Wagon owners to keep their vehicles running and to reduce the shop/dealer costs that some places would soak youin $$$ doing this job.

Peace!

Stev

Great write-up and pictures by stev !

For those that are 'chicken'
spraying the contents
of a $6 can of official Chrysler 'Combustion Chamber Conditioner'
through the little IAT port will help it
but the cleanup proceedure above
can do a more exacting job.

Is it a similar proceedure to clean this on an 89' 318 5.2? I have the same kind of slipping thing in 2nd gear.

I'm not certain since the 89' 5.2L/318cid engines and not Gen-2 Magnum engines. Those are either carbs or TBI vs. TB with injection per each cylinder.

I have limited knowledge on pre-1994 Dodge Ram Van/Wagon vehicles.

Bumping this thread up for those needing this help in the Spring time when buildup is worse after Winter.

Thanks so much for the info. My '99 V6 with 165K miles just would not hold idle or keep running. I pulled the IAC, cleaned it and then went for a drive around the block. Great DIY advice w/ pictures!

I like your article. I will keep this in mind with the van that I am buying. Thanks for the details and pics.

I cleaned mine tonight and on the second start-up found that the van was running smoother and idleing better. It took me less than 30 minutes to complete. Also found a bad vacuum hose on the right side of the throttle body which I replaced.

For 330K of miles, cleaning the IAC must have been interesting to see.

The hardest part of the job is taking the dog-house off.
