Hey guys! So my little :poo:box seems to be fine until she warms up, then doesn't want to rev past 2k. It almost sorta feels like it starts chugging along like a :leghump:ing choo-choo and starts making this gross sound that reminds me of misfiring, but not sure. I could really use some advice as she's my daily and I'd be fifty shades of **** if she died out on me all of a sudden. I replaced the fuel filter due to some friends' advice and it seemed to bandaid the problem for a couple weeks but she's back to this issue again. Does anyone know what I might be able to do to fix it, or has anyone ever had this problem? At this rate, I'm thinking of cancelling my insurance, ripping the 2.3 and A4LD out, and just replacing them with a 5.0 and T5 setup but that'd still leave me daily driver-less. Any advice or anything would be greatly appreciated!

I should be able to have a local friend do that either tonight or tomorrow. Same guy with the test light to check the CEL so will keep updated. I've read that it could be anything from a failed coil pack to the catalytic converter being clogged and that would be a big suck. Lol.

Update: Friend said timing checked out alright, weirdest thing. Had to refill coolant (just got it filled like five days ago, odd?) car seemed totally fine after. What the :leghump:? Lol.

Do you have a MAF sensor? If so, try unplugging it and spray the plug with WD-40 or an electrical cleaner.
I'm thinking corrosion on the pins inside the plug causing intermittent connection issues.
Ford had a TSB on these plug-ins years and years ago...

Did you get any codes?
With the coolant disappearing, compression test and/or cooling system pressure test

I've had a faulty EGR cause issues similar to this as the valve was failing/sticking. Disconnected the sensor, and the computer quit trying to use the EGR system... made it so I could get to my job interview...

edit:
just realized how old this thread is, lol... did the car end up in a scrap yard?
