Bulb was good
. Anyway, just took the chance based on the logic of what the car was doing.
Speedometer would jump, car would not go into reverse, engine would idle weird, I get concerned. Basic order of events.
I replaced the input and output speed sensors on the trans, don't know which one was the fix, but it's good as gold now. The speedometer would be all over while in idle due to the bad sensor (why only in idle opposed to drive, no idea) the car obviously wont let you throw it in reverse when going at any high rate of speed-as the speedometer (and car) was thinking I was going. Engine would idle weird due to the air/fuel mix that the cpu was throwing based on going "x" miles per hour, when in reality, it was 0, with no load-giving the unstable idle.
Hope this helps anyone in the future, thanks for the input! And yes, these are pretty solid cars, bought by ES three years ago at 85,000, now sitting a little over 140,000. For $2700, I can't complain, just wish the rust that we all fall victim to here in michigan didnt happen. Also, the front ends are kinda weak on these, but then again, I do live on a dirt road, and again, in michigan, where potholes eat cars for breakfast. Take care!
