Hey, just a ? for yall! i have a 1995 cadillac sevile sls i bought it in Jan. 2003. It had 100,000 miles on it. It is starting to cut out when you go up a hill it cuts out but when you put more gas to it it stops....i called the dealership and asked them about it and they looked the car up on the comp. and said that they have done maint. on it since 1999 and there was no 100,000 mile tune up done on it. Could this be the problem no 100,000 mile tune up done yet? they said it would cost 200.00 to do one. what all are they supposed to do on a 100,000 mile tune up? I now have 112,00 miles on it. It is a great running car! Just cuts out when going up a little hill. Does this sound like spark plugs and wires? Please respond ASAP! Im takeing it in Tues. Im a woman and dont want to get ripprd off from the dealership. I trust yalls answers more. Please help...thanks a bunch!
