Replying to: spur2 (Jan 13, 2008 8:58 pm) noticed your message.....my 98 had the same issue. I bought the car in the late summer, had no problems until the cold weather seem to hit....I had also changed the wires and the same day after changing the wires, it started to act the same way..it was like someone took the key and turned it off while you were idling at a stop light or stop sign....in neutral or park it did not do it. replaced one crankshaft sensor and it did not do it for the mechanic. brought it home and it started again. replace the other sensor and it did not do it for a couple of weeks. they then had to clean the contacts on the sensor. it has not acted up since (knock on wood). My suggestion is that if you have them replace the sensors make sure they replace both at once and that the contacts at the other end are clean. good luck... i know how frustrating this is, it was like someone just turned the key off and the car would always start right back up.

My Aurora has been to 3 Olds dealers in the last 3 years for diagnosis to correct a lope, or missfire when driving 35-40 mph. the car runs great and gets 17mpg. in town and 27 on the hi-way. The problem started  55,000 mi. and still has it 87,000 mi. Have had wires, plugs, filters, (fuel & air) changed,engine scans, (found no problems) fuel & engine additives tried numerous times. Only time the 'CHECK ENGINE' light comes on is in real humid conditions,(spring and fall) and doesn't stay on long. Premium fuel makes no differrence except for hi-way mileage. Dealer mechanics can't find anything wrong, but notice the same miss that I do, yet say everything checks out so there's nothing they can do. I thought it was in the transmission, but leaving it in 3rd.(no overdrive) increases rpm and the miss is still there! I've had dozens of vehicles, but this problem is a one of a kind mystery!

 1995 Aurora with engine trouble light. Gave it a tuneup; got a $700 estimate to fix these codes: "knock sensor line missing the reference signal ECM trouble codes = 132-27-36-74-119-136-135-134-133. Does this sound like I need a new computer? New one was installed in 2003, and as I can't afford to feed my lovable auto, it gets driven only about once a week. Have already put $5,000 more repair into the car than it's worth so reluctant to do more. (where's that guy with the engine fire who needs a '95 engine - you might get mine!) So can you help me figure this out? Thanks in advance.

to everyone who has had a stalling problem at the stop light and replaced the crankshaft sensors, has this worked? the people that i have had look at the problem, including the dealer, cannot come up with any codes to fix. i'm at my witts end on this thing. have no other problems with the car.

Replying to: sclipson (Jan 23, 2008 10:46 am) I can relate to your frustration concerning this. Mechanic replaced the lower crankshaft sensor, brought the car home and 10 minutes later it did it again. Took it back and they replaced the top sensor (harder of the 2). car ran great for 2 weeks then started again. went back to mechanic, they replaced the ignition wires. 3 hours later did it again. went back and freaked out on dealership. they kept the car for 1 week, it too did not have a service engine light on, no codes and they were totally baffled about it. they contacted Gm and after basically going thru the whole car, decided to replace the crankshaft sensors again and clean the contacts when they connected to. this was 1 month ago and the car seems to be running fine and has not acted up since. hopefully this is the end of the stalling issue. it to was stalling at stop signs and traffic lights and would always start right back up. as per several mechanics I have talked to and many searches on the Olds Aurora Website, if you replace the crankshaft sensors, replace them both at the same time and make sure the contact area are clean. hope this helps and good luck |

thanks for your advise on the sensors. i showed your response to the dealer , and they said if the sensors were acting up, it would leave a trail, i.e. codes. obviously none of us really knows the answer. went ahead and ordered new sensors anyway, as it was'nt that much money. if this doesent work, it goes on the block.

sorry to hear you are having the same problem. no, my problem did not start after having new wires etc. installed. car had been running great untill about a year ago. does not do it very often, but enough that my wife will not take it more than a couple blocks from home. one thought was that the egr valve was acting up but that checks out all right. hopefully the sensors will arrive shortly and can get them installed early next week. its been one fine automobile and my wife does not want to give it up, but will in a heartbeat if this problem isn't fixed soon. i'll post my results as soon as i can . |

| I recently had my 95 into the dealer for a 3rd replacement of the AC comp. All is fine with the AC now, but a couple days after I got the car back form the dealer, after the car sitting for the afternoon it would barely start, but started, and was drivable but running very poorly. The next morning the car would not start. We had the car towed to our mechanic and he determined it was the fuel pump ($650), the pressures were low 12psi, and I guess were SB about 40 something. All made sense at that point. I picked up the car and all seemed fine but the car was still hesitating, when you decellerate and then gradually accellerate, the car would hesitate and backfire. (This hesitation was present even before the AC problem, I was hoping the new fuel pump would take care of this problem.) No such luck. The car still had the same issues so I took it back to the mechanic. The car would now stumble when trying to start, but start and also continued to hesitate as described above.(periodically) The mechanic could not figure out what was going on, the pressures were fine on the new pump, but felt it might be bleeding out after sitting for awhile. He continued to replace the fuel pressure switch. The problem is still not fixed. He tested plug wires, coils etc... with no problems found. The conclusion, it may be a defective fuel pump. He offered to changed out the pump for a new one. I guess we will see if that takes care of it, I have my doubts. Any other ideas??? | |
