Sir, I think my first thought would be your Idle Air Control, It would be best to know if your check engine light is on and what code it is throwing. If you do not know how to get the code I can help you with that too but I will have to do some research, most these used the climate control to access the codes. I may be wrong about that but I know I have used that display before for diagnostics, it may have been only the ac diagnostics. A quick search on google for something like " how to read diagnostic engine codes 1994 cadillac sevile should return you with the information. Most other gm autos you just ground the diagnostic terminal and watch check flash the code to you a code 12 is normal.

I just bought a 1994 cadillac seville sls with the 4.6 litre motor. the seller said the engine was recently rebuilt. the check engine oil continuosly displays on the dash. i have added oil and it seems...

Have you tried putting more oil in, Should have it above the add line. If all else fails have a oil change on it.Have them filled it like they do after and oil change, and then keep and eye on dip stick, If looses oil after that, you have a leak somewhere. Let me know if this advice helps you, Thanks Mike from fixya

Hi 1994 Seville SLS 4.6.fuel pump relay. Is there any way to test

no do not drill no holes wher the gas tank is.the bast way to drop it is to buy a syphon pump for $10 at walmart and get all the gas out. it is located on top of gas tank. to test a relay . take an old phone charger cut the end off that connects to phone wrap one wire to #86 and other to #85 on the relay terminals . it should click each time you connect the charger to terminals. if u have a multimeter use the continuity seting and check terminals 87 and 30 for continuity. it should only beep with power aplied to #86 and 85

My 94 cadillac sls won't idol,so can't shift into drive will only go dead. anyone have any clue how to fix it?

HI,check the air pipes and the slow jets,or on the alternative remove the air cleaner, change the cable of the plugs from 1-2- or 3-4 and try stating the car it will be hard but hold on the throutle and keep on starting when it start it will misfire accelarate for just 40sec then return the plugs cables to their normal positions then start the car it will idle if it is a dust that block the air ways and return the air clearner affter blowing every thing
