My service engine light came on and off several times, so I took my 1998 olds regency to the shop this morning to have it checked and inspected. I was told that two of the fuel injectors needed cleaning or replaced, but the cleaning had to be done by machine and not by using additives in the fuel tank. The cleaning will cost me $189. They will not guarantee that this will cure my problem but if it don't then I am looking at replacing those injectors for a price of over $500. I guess I'll see what happens....just wanted to share this with another olds owner. If the cleaning or replacement is really as costly as is indicated here, I think I'd look for a new mechanic. I had two injectors replaced in my '96 recently. They cost $76 each at Auto Zone and my mechanic replaced them (one at a time, a week's time apart) for a case of beer each time. It's really a job you can do yourself, but I think you'll need some Torx sockets to remove the metal rail that holds the injectors in place. You also need to take a good look at how the accelerator cable (and cruise control cable if you have cruise) connects. My mechanic put some Vasaline type of lube on the injectors before she seated them. Sounds like you could use a Haynes or Chilton manual. FriPilot
