You will probably want to use the computer off the 94 just to make sure everything works properly. Other than that it should work. May have to do work arounds on throttle linkage or maybe some plugs.

Hi...it sounds like your fuel pump might be going...if you can, get a fuel pressure test done.
Let me know if I can help further,

check the belt tensioner, and pulley to make sure that the bearings are not going bad.

Eighty-Eight - 1992-93
Ninety-Eight - 1991-93

Press and release the "TEST" button on the Driver Information Center. This will illuminate "CHANGE OIL NOW" if it is not already illuminated. Press and release the "OIL" or "OIL INDEX" button. Next, press the "RESET" button and hold for at least 7 seconds.

I hope this helps (remember to rate this answer).

the anti theft system is active because of the loss of power
get the owner manual because you have to go through 15 steps to unlock it

Find coil pack I think it is on the front passenger side. Disconnect negative battery cable. Remove electrical connector from module. Remove the four or six bolts that fasten the coil pack/module to the motor. Mark location of coil packs before removing from module. Replace in reverse order.

Hi:
You need to stop by your Olds dealership service department. with your vehicle, and they can get you the unlock code for the radio, using the VIN number of your car.

Replace the ign lock cylinder and chip key.

Look in the lighter hole, and get the loose change out of it. :)
