Scored a neoprene winch cover from tractor supply for just $16:

 

You clean those sensors yet??

 

No, I found a wicked deal on Ebay for under $20 for both sensors. So to save time and money for many years to come, I'll just get them new!

 

Touché, that's a hell-of-a-deal

 

One of them was even an original Mopar overstock (the IAT) and the other one (MAP) is a cheap Chinese one that I'm willing to gamble with lol.

 

NICE!!!!

Still.... for $20 you can't get mad at that deal even if the MAP is no good. The MOPAR IAT would cost you more than that!

 

So I cleaned the throttle body yesterday and I couldn't believe the carbon buildup in the butterfly valve area and in the IAC orifice. I just cleaned it about one and a half years ago. So I cleaned that up and so far, no more idling issues. I think maybe the IAC plunger was just getting inaccurate readings because it was dirty. So I probably didn't even need the MAP and IAT sensors I bought.

But only time will tell if this fixes the issue. I only drove about 5 miles after cleaning and haven't had ample testing time yet.

 

Glad to hear it

 

Yeah so far no more idling problems. It's been a few days now. Cleaning the IAC seems to have done the trick.

 

hmmph! never would have thought of that!

 

I don't know about you guys but cleaning the IAC would have been the first place for me to look. its called the Idle Air Control valve for a reason.... if u have idling problems then that would be a given to check since it is the only sensor on the throttle body that controls the idle...


im sorry I hate to be a complete ******* with this statement but I feel that it just really needed to be pointed out...

 

That's why I said clean the sensors

 

Well the only issue being that it wasn't that long ago that I cleaned it. So I attempted to rule that out as an issue. It seems like just a year and a half is a short amount of time for a clean sensor to get dirty again and start malfunctioning. So perhaps the IAC sensor will need to be replaced soon anyhow.

And keep in mind, I JUST had my new brake lines put in, so I thought maybe a vacuum line could have been damaged in the process since depressing the brakes would cause a fluctuation in RPMs (it went higher, not lower) when this issue occurred.

I did not blindly make a choice to just buy components. But I did anyhow because the price was just too good to beat, and for Mopar parts (hell yeah). Basically, it had a lot of strange factors that the regular guy would not typically have to account for.

 

believe it or not, with the gas that we get today a year and a half is actually pretty long. i clean my throttle body on an almost 6 month basis to make mine running good. although that could be caused by the **** gas we get up here in NY, especially in the winter.

but its understandable of what you are saying as your reasoning.

 

How would dirty gas affect a throttle body on a 4.0? Injectors are down streem of the throttle body. I would lean to bad sealing on air filter duct work or bad air filter it self. Just my two cents could be off though.
