my 1995 STS acts up as well and I need help BAD!!! :annoyed: First off she has about 189K on her and I paid $4040.00 exactly for it two years ago, when she had 162K on her, did a tune up and new exhaust when I first got it, was told that I needed new mounts then, never got around to doing, the dogbone style ones up top are showin some wear, My tranny was acting up reving hard into second, and always wanting to slam back down to like 1500rpms right when you let up of the gas, even at interstate speeds, Im pretty sure the tranny needs some work. About a year ago, I had a problem where it wouldnt start at all, I ripped apart the steering column thinkin it was the ignition swith, wasnt that, so I had it towed up to Cadillac where the said the transmission transponder switch was messed up and the car couldnt tell wheather it was in park or drive. That was $450 right there. Now present day im stuck with the same dilema, go to start it and nothing no wanting to start or even a turn over, it just clicks from under the hood, like the something is relieving presure, (have yet to get the recall fixed on the fuel rail) Sometime though about a month ago, it would go in and out, like go on a streak where it would start for like 3 or 4 days and then go on a 2 week streak of not starting, and now its been sitting for atleast 3 weeks on its longest sitting period to date. Im pretty sure but not positive its not the starter, not the alternator, replace the battery today, and Im clueless what it could be. I can pull up trouble codes but most of them arent on the online look-up thing that everyone on here uses. If anyone can share info that will help I would appreciate it. Someone also said something about the ignition coil?? INPUT NEEDED!! I ran another OBD test and some of these codes I couldnt find, S011 , S013, S018, S023, S028, S051.
