    Cylinder Misfire

    if it is still under the 3/36 then you qualify as the customer (since you are the owner)! go and make a new warranty claim, with the proper plugs in it! mike

    Cylinder Misfire

    carbon build up just information (fyi) i believe the cause of this whole valve not rotating tsb was do to the valve train rework in 05. these 3.7L and 4.7L will build up alot of carbon if you short trip them and use discount gasoline with the epa minimum detergent! this explains why some...

    Cylinder Misfire

    i agree! but some of these dealers won't give you access to warranty work on the ignition/ motor work, unless factory oem plugs are in, and the problem still presents. i am now out of warranty now and soon i will change the ngk's out for another copper core brand!

    Cylinder Misfire

    well there you go, you can not assume they know about the tsb (especially if it is a low volume dealer!) you are going to have to be assertive in a firm but calm way and ask them specifically about the tsb and tell them you want this problem covered under the tsb! i gave you a copy of the tsb...

    Cylinder Misfire

    At that time nothing was mechanically wrong! the valve not rotating (according to the tsb) is an intermittant problem! thats why their is revised valve locks according to the tsb, this ensures valve rotation like it is suppose to! second change the plugs out for the oem ngk's. why would you...

    Bought our second KJ - Bad news

    thanks for the update.let us know more detail when you get it! an o-ring doesn't sound right, because an o-ring doesn't exist in the valvetrain for #5. mike

    Bought our second KJ - Bad news

    in reference to t.s.b. 09-007-06 below is page 1 and 2 of the tsb. it will be important to ask the dealer for the miss fire count at idle. around 10 and you qualify for the tsb, if you are under warranty. page 1: http://home.comcast.net/~merchjo/jeep/jeeptsb-page-1.jpg page 2...

    changing trans fluid/ will this work?

    i wouldn't try it. compressed air can blow moisture in the trans causing bad things to happen. not to mention when the vehicle is off there is no flow in the trans, causing a lot of check valves to be closed. you could damage alot of things! mike

    Engine problems

    it might be worth taking it across the border if it is the following tsb (which i hear applies to the 2007's) it costs 2000grand to have it done. tsblink page1: http://home.comcast.net/~merchjo/jeep/jeeptsb-page-1.jpg page2: http://home.comcast.net/~merchjo/jeep/jeeptsb-page-2.jpg as...

    Engine problems

    what do you mean no warranty? it should have the 3/36! if it was bought new in the summer of 06 (earliest you can get an 2007) then it should have 1 year of warranty left! mike lastly if you don't have the blinking cel (hard missfire) read with in 30-40 key cycles the pcm clears it. mike
