Yea I was going to say possibly a plugged cat, I had this happen on a Dakota a few years back, drove like absolute crap and threw codes that would change.... I'd at least mention it when your at the dealership....

Never knew anything bout the dielectric grease will do that this weekend...like I said if the coil packs don't fix the prblm it's going back to the dealership shop next week. You are right about the someone told me this and someone told me try that I've done alot of that, but I still have'nt spent all that much on it yet just things that obviously need to be replaced anyhow... I do believe it will still have saved me some money on repairs that I have managed to do myself such as the 360 and some dollars they wanted to charge me to replace my FPDM and 1 coil pack. Who can afford that when you literaly only disconnect 3 wires and take out 3 bolts between both parts and the FPDM was 104 and some change after taxes and the coil pack is only just under 45 bucks, it's hard enough to put gas in the tank.....I'm not knocking the advice, and I'm very aware of my limits. That is why I asked for advice....lots of times vehicles of the same make and model and year have similar problems...I do believe my cats are prbly part of the problem and those are expensive ....things like the plugs breaking I blame on poor design on Fords part that is something that used to be a simple at home replacement job now can end up costing you almost $1000.00 to fix. In my opinion that is just one way to ensure the working class people keep on putting there money into circulation...I do believe the cats are prbly going bad like someone else mentioned if they were'nt before they prbly are now...

Good luck to you. Hope it all works out.

Took Swegner 99's advice talked to the service manager they took it right in...both cats clogged bad cop's on cylinder 1,2,7. Thanks guys. Gonna pull cops grease them as recommended when replacing the other 3...as for the cats well i already have true dual exhaust i guess it's gonna get alil more "true" and that opens a whole new bucket of worms...it's friday and i'm gonna get buisy on this thing...

She'll be sounding loud and running smooth after those cats are swapped out! And after the cop's are fixed.... I'm sure you'll let us all know how she runs and sounds! Good work
