Slightly off topic since this is about my 2008 Jeep 5.7 Hemi engine.
Took it to Dealer for 35000 mile service today and they recommended throttle body cleaning since they said it was dirty. Price $199.99, discounted from $249.99.
Said they use a machine it takes 45 minutes and gets cleaned well and should increase gas milage by up to 2 MPG.
I went along with it since I made a snap decision while driving on the road and I want the Jeep running up to par for the winter. But, after googleing the procedure I am not even sure if the 5.7 is supposed to have cleaning done to it. I have cleaned throttle bodies on Mustang and GTO myself and cannot see why this must be so expensive and what machine do they use ?
Anyway any input form the forum is good for me to hear.
BTW, I have three cars with the 5.7 engine so I am very curious. ( 2006 Charge , my wifes, 2008 Jeep Grand Cehrokee and my 09 B5 bleu 6 Spd )
thanks and Peace
