Tossed 2 codes this weekend while it was all rainy outside. Random misfire and left bank catalytic converter. The good thing is, the cat is covered up to 8yrs/80,000mi, and I have 68,000 on the truck. So I just made that. The bad thing is, they have to order the part.
As for the misfire, (I am sure they are related) as the they came on at the same time), they wanted to sell me a tune up for $450. PCM update, fuel system treatment, and spark plugs.
My response was, "I just had the PCM updated a year ago. Now you want to charge me to update it again?"
Ford Rep, "Yes. It looks like a new update is available. You know how your home computer receives updates? Well, it's pretty much the same thing."
Me, "Yeah, my computer updates for free, yet you guys want to charge me to do it. So are you telling me Ford wants to nail me $100 every year because they can't get the programming right?"
Ford Rep, *no response*.
As for the fuel system, I told them I just had it done a year ago, i'm not doing that again. And the Ford spark plugs cost $26 from o'reilly's, and 30min of my time. I'll pass. Please just order the cat and let me know when it will be in so I can bring my truck back to have it installed.
lulz. good times.
