Haven't looked at a newer GM, but the problem always used to be the cruise control, usually the short cable from the cruise module on the drivers side inside fender. Don't know if they still use the same system or not, but something to look at.
on the distributor or near there

I believe there is no 1998 Oldsmobile Delta 88 but there is a 1998 Oldsmobile Eighty Eight. The procedure is the same for the Delta 88 and the Eighty Eights - only the size of the side lock pin changes. If you lookup wiper blades by make, model and year, you'll get the correct parts with the correct side lock pin size. The 1998 Oldsmobile Eighty Eight has fairly unique "1/4" side lock" wiper arm attachments. See Sources and Related Links below for installation videos. Also, purchase the replacement blades first and there will be additional instructions/illustrations on the replacement packages. Its very easy.
U need a new speedometer cable. It runs from the transmission to the speedometer. They tend to break in half or just seize up after they get so old. They are easy to replace, it takes to people to do it but it is really easy to do. I hope I helped you.
Which year? Which model? Which engine? Which transmission? Oldsmobile made the Eighty-Eight for over 50 consecutive years. Please be more specific.
I never saw this model but the transmission filter on every transmission I ever did see - was -inside the transmiision bottom cover.
