#2172 of 4484 Hesitation again and again...
Sep 22, 2004 (5:25 am)
1997 Oldsmobile Aurora 91,000
Currently my vehicle is hesitating. At idle there is a slight knock/shutter every few seconds sometimes not even noticeable. When accelerating you can feel the lack of power but the engine runs smooth however when the vehicle gets into fourth gear and low 1500 rpms the hesitation is much more pronounced. At higher rpms and highway speeds the engine is smooth however still with the lack of power. I have changed all the plugs/wires/coils/control module with AC/Delco OEM parts. Plus have installed a new PVC valve and fuel filter. After I did the above the car ran fine for a few weeks then the same problem occurred again. I had AutoZone run the codes which came back O2 sensor high voltage and cylinder 7 misfire. I changed the # 7 spark plug again with AC/Delco platinum for another $6. Car ran fine for a few days then the same problem. Same cylinder # 7 misfire although I pulled the plug out it looks fine however there is oil on the threads and on the tip of the plug. Is this normal? So before I change my third # 7 plug what else could be my problem? I would hate to have to bring in the car to the dealer since I have not had to yet except for the recall. Any advise would be greatly appreciated! Thanks in advanced.

It might be the O2 sensors as you mentioned. It seems weird, but I've heard good results. I plan to include them in my projects as soon I can fit it between college and hurricanes (Jeanne is on us as I type).

As for switches to control your heated seats, try looking at the controls on each front door just forward of your shoulder. You will see a light on when the seat heater is on and it won't take long to heat the seat of your pants and your back.
Try searching eBay "1997 Aurora Service Manuals" include the year of your car and don't buy the wrong year. I found a three book set for our '97 "G" Body (Aurora and Rivera) for $69. and an Aurora owners manual for $15. Start with the owner's manual. You will learn more about your car in that small book that fits in the glove compartment.
#2175 of 4484 '97 Aurora runs poorly or very bad on warm start
Sep 26, 2004 (12:57 am)
Our '97 Aurora runs great and gets 18mpg in town and 26 Hwy. but, on several occasions it develops a serious run problem (only after restarting a warm engine). It drives great for 5 miles or 25 miles but when we stop for ten minutes at the store or a few minutes for any reason, it may start OK and then die when you put it in gear. If it keeps running it will not develop enough power to drive even three miles per hour. If you let it stand over night or for any multi hour shutdown it has never failed to start and run like a new car. It has had a new fuel filter, new AC Delco platinum plugs and the factory recall for the "fuel rail" replacement to stainless tubing. All codes have been cleared and none have returned. On first startup it has never failed to start or run great for hours. On two occasions I have gotten the problem to correct itself after shutting down and restarting multiple times. It is only a problem on SOME WARM STARTS. Maybe one in twenty warm starts has a problem. It can set in the hot Arizona sun for hours and always starts fine. The problem has only happened six or seven times in three months. We use only Top Tier Premium Detergent Gasoline (Chevron Premium) and Castrol GTX 10W-30W oil. The dealer told me I had a fouled injector that was fooling the computer. If that were the case, why does it always run great after setting for a few hours? One time it was only able to run two or three miles per hour. I stopped and turned off the engine and restarted several times then suddenly it started and ran like a new car. Once it started and ran poorly even up to 60 MPH down the freeway. We drove home 15 miles with it still acting like it was taking its last breath. The next morning it started and ran like a new car. It will run great for weeks and then suddenly it has this problem on a warm startup. Can any one help solve this problem? The Aurora is beautiful and enjoyable to drive but, I won’t have a car if it can’t be ready to go when I need it.
I have owned two 4cyl. SAAB 9000s over the past 18 years and only once in 250K miles was the old ’87 out of service when I needed it (idler pulley bearing failed). My ’93 has never had anything worse than a battery problem in 100K miles and it is still running like new. I sure hope GM “limits its improvements” on the SAAB. If I don’t find a resolution for my Aurora’s warm starting problem soon, I will find myself a nice clean ’97 SAAB 9000 AERO hatchback, a real SUV not a gas guzzling tank. I will settle for an American Classic Oldsmobile from the '50s for my toy.

I seem to remember intermittent starting problems like you describe related to the fuel pressure regulator (FPR). It is supposed to be a relatively inexpensive fix that you can do yourself.
I think it's right under the plastic engine cover.
I hope some others can confirm this or offer something else.

The FPR problems were when the car didn't want to start. The engine just turned over for 5-10 seconds. It sounds like vlenox's car starts fine just runs terrible. I thought it was an ignition prob. but sounds too random (though I'd check it anyway). Though, if you left an Aurora with a bad FPR for a couple hours, it started/ran fine (just like vlenox said). I'd replace it anyway as a "preventive maintance" step for a 8 year old car.

Yesterday was my very first trip to the shop for my Aurora (in the 4 years I've owned it anyway). I took it in for the fuel line recall. They were kind enough to throw in a new fuel filter since they replaced all the chassis lines. I also got a brand new fuel pressure regulator since I had replaced mine with an aftermarket one that didn't match up correctly to the new lines for some reason. They did an awesome job, the new stainless steel lines look great. The total cost out of my pocket was 0$.
Overall it was a very pleasant experience. I just hope I never have to go back!

I am now the proud owner of 2 Aurora's, a 2001 (which I've had) and a 1997. My wife thought I was a little obssesive about the 01, but now that it is hers, I caught her in the driveway the other night cleaning off bird crap, which she just used to let accumulate on her Venture van.
Anyway, I've had this 97 for 8 days now. When I first filled up with premium at Speedway/Marathon
it set off the SES and the code was water in fuel. Bought a can of dry gas, light went out. Filled up again yesterday and the light came on again. Does anyone living in the Ohio/Kentucky/Indiana/West Virginia area know of a good fuel for these cars. My choices in Cincinnati are Shell, BP, Speedway (this is the one causing problems), Thornton's, and that's about it. Sorry for the lengthy message but if anyone can help, please let me know.

I'm not in the area, but I think Shell V-Power is regarded as the best there is. I use it during the summer.

Sat. I went to the Cadillac dealer for the recall. I'm living at UCF and the recall notice went to my mom who lost the paperwork. Anyway we went to the Dealer who didnt know if they had the part. So I left the rora there for the day and they said they would call if they could/couldn't get the parts, so I could return home Mon. (the Cadillac dealer was at my home town).
First, whatever the pipe in the front is, the one that goes from the intake elbow to next to the oil cap, I think front PCV?, they had a rubber piece clamped over it, like it was in two piece. The guy said "That's the way we got them from Oldsmobile. I know, I picked them up myself." When I got home, I pulled the hose and it was definetly broken. Just want to make sure you guys didn't get a new piece with your recalls.
My other concern, is that he told me that, its just an inspection of the fuel rails and a replace of the lines. I can tell there's new connections by the brake booster. I have to go make sure I got the complete set of lines and check they didn't con me there either.
It just sounds like you guys got new stainless steel fuel rails. Did the service guy say anything that sounded like this? Does that mean, your rails were in bad shape and mine are good?
I just really feel like I got the fork up my rear end.
