Oldsmobile - Stall - Gasoline - Pump - Misfire :: 1998 - Hesitates / Stalls / Sometimes Backfires?
Feb 16, 2011
My 88 "Rosie" has been having problems for months. It hesitates, stalls, and sometimes backfires. This is an intermittent problem, though it is happening more often lately. I took it to local auto shop and their computer showed Rosie was throwing a misfire code as well as a lean code. I took it 3 months ago, and I took it last week, got the same codes. The lean code led me to check the fuel pressure. I did and while it should be healthy 48-55 psi, I got 48 for awhile then 15 PSI! Now I'm thinking fuel delivery. I started with the filter. Sure enough it was dirty. Weeks later, the problem persists. I replaced the fuel regulator (ok, mostly because it was cheaper than the replacing the fuel pump, which I really didn't want to have to do.) Still, no luck, so I finally caved and spent $200 and 12 hrs dropping the tank to replace the fuel pump. Guess, what? Still no dice. I'm still getting the hesitation and the misfiring. I haven't put the fuel pressure tester back on it (been busy) so I don't know if the pressure is still low or if these other things are even related. I thought my logic was infallible. Let's face it, there's a finite number of parts that control fuel pressure. I'm running out of parts to replace. Where did I go wrong? The only thing I can think of that could still do it is perhaps the fuel pump relay? I dunno. Would it work off and on or fail completely? I'd love to get some opinions on this.

2006 Chevy Express 3500 ... Vehicle surges, hesitates, stalls, backfires, and is hard to start after stalling.No codes are thrown, and have had the fuel system checked out without results. 159.000 miles. last mechanic said it was not a spark plug issue. Been an ongoing problem for several months and getting worse all the time.

I have a 1998 Honda Civic LX that was converted from automatic to 5 speed. It hesitates while I drive, only sometimes. Normally it does it when I am pulling off from a stopped position or when turning the corner and then accelerating. I will have my foot on the gas, but it won't gain speed unless I hold in the clutch and rev up the engine then it will pick up speed and go fine. Then sometimes it also hiccups while driving without accelerating, I can feel the car jerk a few times and start to loose power.
I will need to down shift to third, or most often 2nd gear and rev it again to gain power and to pick back up speed. Things done to it since i bought it only a few months ago by the person (who is a mechanic) I bought it from: oil change, fuel filter changed, Lucas gas treatment added (by me), new exhaust system installed, starter replaced. I am nervous that it may be rear-ended, or t-boned in heavy traffic. Should i have the fuel filter checked?

When my 1998 Mustang has been stopped and started numerous times in a short period--say, like when you're running errands--the idle will sometimes (not always!) get really low (below 1000 RPM), and will stall out no matter how much gas you give it. It will then refuse to start for about 30 minutes. Then it'll start back up and run fine for another week until the whole thing happens again. The car runs fine in all other respects, and again, it's seemingly random, and only after the engine has been stopped and started several times. It won't for example, stall out first thing in the morning.

I have an '04 Subaru Forester which sputters and stalls after fill up. It sends error codes for cylinders 1, 3, & 4 misfiring...I only have a 4 cylinder car - This only started Friday - a few days later and I'm really getting desperate. I screw my gas cap on, we check the connections...and we've read all kinds of random solutions that spread across the board.

My car runs great except occasionally after I drive awhile, park and than restart to continue, it starts right up but stalls out 20-30 seconds later. I turns over but will not run. I have to let it sit for 30-45 minutes and than it starts up like a champ. I suspect fuel pump but would like an expert opinion. Garage says they can find nothing wrong and to bring it in when it happens... how do I do that.

This problem showed up this summer, different times under load: on hot days, going uphill, AC on. Also, always happens when the temp gauge is just above halfway. Even after a stall, I am able to limp home, and it improves the longer the car runs after the problem starts. First I replaced the fuel filter which was pretty dirty, the problem didn't improve, so had the shop run codes -- low ignition voltage. They replaced the coil, and that seemed to work for a while. Now, in109 degree heat, it's starting to hesitate again, but the engine light hasn't come on this time. I had to replace the radiator about 4 months back, when it was cooler, and don't know if it's somehow temp related. Also, haven't replaced the timing belt since I bought it with 90K (its has 119K now).

3 mechanics can't find what is wrong but when I come to a stop sign or light my car stalls, not every time but a lot. Also, seems to happen more in cold or wet weather. So every time I stop and idle I have to quick put it into park.

I just changed the fuel pump on my 98 Isuzu Rodeo and now it wont start. The pump is getting power because i can hear it humming. Fuel is getting to the fuel rail, I checked the the shrader valve. I tested the battery and its fully charged but it wont start.

I have a 1998 Oldsmobile Aurora with 103,000 miles. I'm receiving the codes P0300B Misfire and P0440B Evap Emission.
I use Premium Unleaded gas (not at a cheap station) so I don't think it's the gas causing the misfire code P0300B. Also I've put on a new gas cap but I still get the Evap Emission code P0440B.
Working on a 1998 Oldsmobile Aurora with these 2 codes?

1987 olds delta 88, 106,000 miles Pulling out onto the road one day, my car died and would not restart. Was idling fine, happened when I hit the gas. Here are the things checked. Ignition control module and coils checked ok at autozone. I replaced the cam and crank sensors, the coolant temp sensor, the plugs and the tps. Most of the time it will not try to fire, it backfires sometimes. I has started twice, but then would not restart. I have spark and fuel pressure, but will not even fire with starter fluid.

We will start with the history. I recently purchased this car knowing of a long list of issues which have been worked out for the most part. The related piece would be random misfires which I believed were based on a faulty Ignition Coil (common on this 420a [2.0 NA] motor.) I have replace the coil but the issue persists.
Now what is happening is after about 20-30 minutes (or miles) of driving the fuel pump will overheat and the car will stall. I can get it to turn back over most of the time but it will stall out if attempting to drive. I have to leave it sitting for about 15 minutes to be able to move it.
What codes am I getting from the CEL? Nothing. (No CEL)What have I tried so far? - Fuel pump has been replaced- Fuel filter has been replaced- Fuel lines have been verified (no noticeable leaks, unwanted bends, pinches or breaks)(I also verified that this is not an issue with the PCV valve or EGR [electric in this car] valve)
I know... I thought relay or wiring also - but all lines and the relay are cool to the touch so they are not overheating. 1998 Eclipse GS....

My '96 Dakota SLT 6-cylinder pickup backfired and blew a hole in my muffler ... I've had it in three different shops on six occasions since and the thing still hiccups, backfires, stalls ... most of the electrical switches and sensors have been replaced ... right before it back fires, it feels like it is going to stall, then "POW" ... sometimes it continues to run fine for a little while after that ... then it happens again ... When it stalls it feels like it is running out of gas ... it is almost impossible to restart right away, but if I wait a few minutes, the starts right up ...

ok, i just became the proud owner of a 71 dodge dart.. fuel pump was not working, and am converting to an electric (airtex e8016s) and am told i need a relay. airtex doesn't seem to have one, is there another i can use? fairly new at this sort of thing, but have fixed a 72 honda motorbike, so not afraid of engines or whatnot.

My 2000 Oldsmobile Intrigue (Automatic) has 142,000 miles on it. Our car has been hesitating when I drive on occasion. It does it randomly, it was once or twice a month, now it's about 3 or 4 times a week. I can be either trying to accelerate from a stop or already going 50 and trying to speed up to 65 or something and it won't go. The RPM gauge will fly up to 3500 and my MPH gauge will not move.
When it does this the "Check Engine Soon" light flashes, but as soon as the episode is over, shuts off. It does it anytime of day, whether it's the first time started for the day, or been running for hours. In recent months we've replaced the battery, the starter, the timing belt, recently the fuel pump as well as a few O rings. We are tired of fixing this car and not having this problem taken care of. Our mechanic can't seem to find anything else wrong.

1994 olds 88 royale with 3.8 sometimes hesitates or "bumps" when accelerating. sometimes it seems like the tranny is slipping, but other times it seems to feel like poor firing or slight misfire with hesitation. when at highway speeds of +50 it runs fine but occasionally bumps or seems sluggish if i rapid accelerate or speed up to pass. do i have a tranny problem or poor performance or emissions problem.

I have a 2008 Hyndai Elantra with an automatic transmission. Since the first week I have had my car when the fuel is low (under a half of tank) the car tends to hesitate like it wants to stall, or momentarily shifts into a higher gear than it needs to be for the situation; the rmp's get very low. As the tank drops further below half full, the problem gets progressively worse, especially while trying to accelerate hard; i.e. entering the highway, starting from a red light, etc (times requiring a lower gear). I have brought my car to the dealer for service three times also asking them about this problem. Each time they can not replicate the problem which seems ridiculous since it is difficult to not have the problem when the tank is low.
The day I purchased my car I was speaking with another Elantra customer who was waiting for her car in the service department. She had just purchased her vehicle as well and already had to bring it in for a fuel pump recall. I believe the recall states that the fuel pump fails and causes the car to stall, sounds very similar to what my car wants to do. I have asked about this recall on my vehicle and have been told that it does not affect my car.

I have a 1992 Oldsmobile Cutlass Ciera 6 cyl.The car starts up and runs with no problem. However every two to three weeks while I'm driving the motor will just die on me. It doesn't matter where I am or the speed I'm driving it will stall. It takes about a minute and the car starts again, but I need to get this fixed!! My mechanic says it isn't the fuel pump, fuel filter or the crank sensor. He is a good mechanic too.

The 93 Cutlass Ciera 3.3 6 cyl. is hard to start..takes like 3 tries to start it...even after changing..oxygen sensor, MAF sensor, coil pack, fuel filter, air filter, good plug wires, crank position sensor, fuel pump, sending unit....if idling low will stall sometimes. Mechanic said it's slow getting spark up just when starting it..not sure why..

I have a 1987 ramcharger with a 318 and auto tranny. I just put a new carburetor on it. The previous owner partially deleted the lean burn system but didn't change out the carb. I put a Carter 2bbl on it. The truck will start fine and drive fine until I try to go down hill, it then stalls. It doesn't do it as much going up hill, but is still a problem then. If I keep on the accelerator it stays running. I cant figure out what the deal is and is absolutely driving me nuts.

I have a "56 thunderbird with a mid-60"s ford 390 engine w/ 4 bbl holley. I just had engine completely rebuilt and everything else is new: carb, distributor, electric fuel pump, fuel tank, etc.
Problem: car stalls and dies after a few minutes of driving. Generally restarts after waiting about a half hour, but not always. I have a fuel filter with clear bowl in fuel line just ahead of carb. The bowl is usually about 2/3 full of fuel, but general appears empty when the car stalls.
After waiting a while, the bowl refills and the car restarts.
