2004 Mountaineer will not rev past 3 grand
Alright....so I blew the front differential out of my mountaineer awhile ago. I just recently had a new one put in and it ran great for about 2 weeks. All of a sudden it started losing power, wouldnt go up hills, and wouldnt go faster than 10 mph or rev past around 3k rpms. Its throwing two tranny codes : incorrect gear ratio 1 and incorrect gear ratio 2. I cant help but think its the new differential, but A) why would it run good for 2 weeks before going crazy, and B) why would that limit the mph and revs? Ford said a clogged cat will make the tranny throw codes and make it run that way....but I dont know. im at my wits end with this truck as it has been nothing but problems. Any and all help is greatly appreciated. Thank you.

not sure yet....havent had a chance to mess with it because of working 2 jobs, etc. Its really looking like a clogged cat though. I need to find a y pipe off a mountaineer and try it out, cause you cant hollow out the cats on these, or else i would.

fixed this issue as well. Plugs were shot, wires were shot. I replaced the air filter, plugs, wires, and an o2 sensor and its perfect. the o2 was shot and the plugs were fouled causing a really bad miss. shes all good now, hope this helps others. thanks guys.
