OK... I'm new to posting on Focus Fanatics, but I get a lot of good info off of here for some things... but when I did a search for engine codes I got BUBKISS for hits. Then when I started manually searching i noticed 99% of the threads on here are for performance mods... is this the right/wrong forum for just maintaining my focus? Is there a better forum for that kind of stuff?
OK... now on to the real issue besides if I'm lost...
I was working on the car, and decided to change all 3 engine mount... no problem. I did the top 2 in about an hour, and then went to do the bottom one and thought I should put the jack under the mount to see if I could get it to come out... BAD IDEA (!!!)... I heard a loud pop like a wire pulling loose froma connector. I immediately dropped the jack and looked everywhere... couldn't find anything broken or loose. Went ahead and swapped the tranny mount (easy as pie... this car is so easy to work on). and put the car down on all 4 wheels... started it up and it ran smooth as glass (it used to shake like a hound dog passing a peach pit)... well my wife reports to me the next day that her car has a check engine light. I went out and it throws the following codes... P0401... fails the following tests... TID $56 is a little low (32718act/33536min) TID $61 is a little high (29428act/26214max) and TID $50 is off BIG TIME ... it's super high... (37505act/2000max).
Does anyone know what that code represents? I have been all over the back of the engine where the "pop" sound came from and I can't find anything broken, loose, hanging... nothing visible to the nekid eye... or maybe I'm just not looking in the right place.
Any help would be greatly appreciated.
I'm going to heck for vacuum leaks with the "carb cleaner" check. i don't expect to see anything, but you never know. I'm thinking I busted a wire or broke loose a connector but I wont' know until I find it and I'm afraid that means tearing the top of the engine apart... which just seems stupid since the car RUNS FINE (!!!). It runs better now than it has in 3-4 years (of course I also did a full flush of the transmission... so that's probably why it's running "smoother" when we drive it).
