I purchased my Black 09 6 speed R/T on Nov. 7th 2008 . Build date was Oct , 8th 2008 at 8 pm . From my local Dodge dealer . Records show the miss fire started at 500 miles on the car. Engine coughing and barely would run . This problem continued for the next two plus years about every 2 to 4 thousand mile's between the miss fire and engine not wanting to run . Till about a week ago. When local dealer pulled the # 5 cylinder head . Was told for sure that # 5 cylinder had a problem by look's of color in that cylinder . They sent the head to a local machine shop . To be checked out and look closely at the valve guide's . Don't know if they got new information from higher up at Dodge or what. But the machine shop told them the head was junk . And the guide or guides in # 5 where turning in the head . And Dodge said they could not be replaced . So now a new head is on order . And none are in stock at this time. I'm sure the guides may or may not be put in automaticly by a robot or someone with blood in their veins. Don't know . Don't know if maybe they got some bad guides or what . Just know after local dealer has replaced a lot of parts to try and find my long term miss fire . New crank sensor , coil packs , engine computer . And recently they did a compression check on all cylinders wich showed normal . None of these thing's fixed or cured the problem . And now we know why . I have almost 52,000 miles on my car . And have loved every min. and mile . Except the miss fires and not knowing if could get it to a dealer without a flat bed truck . The engine has had many times it felt as if it had lost alot of power . I guess it did . Will keep everyone posted . And pray they get a new head soon . And my Black R/T is healthy and strong again . Or maybe for the first time as I think Scotty would say on Star Trek . FULL POWER !!!
