P098 High RPM P/N to D/R Shift Under ISC

your probably reading those off the same site that i am, but thats just what i understand them to be. where you go from here i havent a clue on those. atleast you can tell that many of them are related, if not caused by the same thing.

thanks for the info. this car is idleing eratically, then dies out, but starts right up again. i noticed the ISC motor going bonkers too, i think that has something to do with it. the owner claims he had a new distributor put in less than a year ago, but im not sure on that. if so, they could have messed up that job (if i didnt do it, it wont work right!:D). i think the p98 code also tell me there may be a problem with the ISC motor, so i think i can fix her from that. thanks again illuminaP.
