Honda - Accord :: 1998 Not Starting - When Turn A Corner RPMs Drop Like Running Out Of Gas
My 1998 Honda accord coupe 3.0 has 225 k miles has a new sending unit, fuel pump, main relay, ignition switch, and spark plugs. I cannot find the source of why my car will not start I replaced these things on my car due to car didn't want start. Then it was fine every time I would turn a corner or drive it rpms would drop like I was running out of gas then it would die now it will not start.
I have checked all fuses. I have read in forums that this could take a lot of money to fix only because no one knows the source of why its not starting. I am a disabled female that is just trying too have a running vehicle and can't figure out why it won't start. It has a new battery but won't hold a charge. Had charged it from my friends car for 25 minutes it gave it enough juice to put it in neutral and push it in the driveway with another car.
Lexus GX 2004-09 :: Engine Stumble Only At 1500 RPMs If In Park Or Neutral
What could cause this? I have 100k and I only notice this if in park or neutral at 1500rpms. It goes away before and after and it seems to drive very smoothly. I had a bad alternator and I just replaced it but the "new" one is making a high pitching ringing so I'm having the shop change that out for a new oem. Any chance it's the alternator or could this be something else. I have sea foamed the throttle body recently and cleaned the maf recently and changed the air filter. I didn't do plugs but they are do at 120k

Twice now this has happened to me and I'm concerned it will become worse if I don't fix it. Driving down the road my engine has disengaged. By this I mean the vehicle both times has been at 55 MPH, my foot on the throttle rpms riding around 1300 revolutions, and the engine disengages rpms drop below idle and my "wait to start" light comes on. This both times lasts approximately 2 seconds and throttle reengages while still traveling 55 MPH, "wait to start" light goes off and its like it never happened. What's going on with my truck?

At the beginning December I put my brand new winter tires (general altimax arctics) on the factory steelies and put them on the car gearing up for the snow. Not to long after the install I notice that I was getting a very strong engine vibration starting at 3,000 rpms and it stopped around 3,100 rpms no matter what gear I was in. At first I though it maybe just the cold affecting the engine. Well...
Last week I put my summer rims and tires back on for the 1,600 mile trip to MO and back, and like magic, no more heavy vibrations. Smooth acceleration throughout the normal driving rpm range. I just changed the oil and tranny fluids Tuesday after we got back and with the warmer weather the car is running smooth as silk. Still an awesome car with awesome mileage and couldn't be happier.
Ford - Explorer :: 2002 V6 2 Wheel Drive Will Just Shut Off / Engine Shudders And RPMs Drop
I think it's possessed! My sisters vehicle, a 2002 Explorer with a 4.0 V-6, automatic, 2 wheel drive will just shut off. At first it acted like it would vapor lock. But it would start right away. then the a while later, (several months), it got where it would drop rpms and the engine shudders, sometimes not dying.
When this first started, the throttle body was cleaned, a new air filter installed, fuel pressure checked. Everything checked out and for a few days it ran fine. Then it started all over again. There has never been a code thrown. All of this goes on only when the ambient temp is above 70 deg.'s. below 70 deg.'s it runs perfect.
Last week it went to the mechanic again and a new crank speed sensor, fuel pump, and diagnostic done. He could not find anything wrong any where. Took it for a test drive and it dyed on the mechanic. Still no codes. What the problem might be? Every Mechanic that has looked at it has gave up, one even saying, " it's possessed."

Intrigue :: Turns On / RPMs Drop / Engine Sputters And Dies
'99 Intrigue (3.5L) with 65k miles. The car has sporadic starting problems where turning the key in the ignition turns the starter motor and results in one of the following scenarios:
1) The engine does not turn on.
2) The engine turns on, RPMs drop and the engine sputters and dies.
3) The engine turns on with no problems (like this morning).
It does not appear to matter whether the engine is hot or cold.
Reading forum posts of people that have seen similar problems, several different solutions would seem to be in order:
1) Replace fuel pressure regulator.
2) Replace crankshaft position sensor
3) Replace camshaft position sensor
4) Replace fuel filter
5) Replace spark plugs
6) Replace idle air control valve
7) Clean the throttle body
Since I rather not start throwing money at the car by replacing parts one by one until the problem is gone.
Subaru - SVX :: Rough Idle / RPMs Drop Very Low And Engine Shuts Off
1997 Subaru SVX (Alcyone) LSi, 3.3L H6 engine.
My SVX was driven from Denver to Las Vegas, NV and it developed an odd habit where the RPMs would start to oscillate while on cruise control. I had to disengage the cruise control to get the oscillations to stop. Three days later I was driving the SVX to work and the RPMs started oscillating at idle and the car started running rough and it died.
These things have all been replaced with OEM grade parts: Spark plugs, electric fuel pump & strainer & fuel filter, Mass Air Flow sensor, new air filter and fuses.
The car starts up fine but after a few seconds the RPMs begin to oscillate. Then the car tries to recover, the idle becomes rough, and the the RPMs drop very low and the engine shuts off.
Santa Fe (CM - 2007-12) :: 2010 - RPMs Drop Low After Engine Turns Over
I have a 2010 Santa Fa GLS. 88K miles. This issue started in the last 6 months, once the engine turns over the RPM drop low and starts to putter as if it is not getting enough fuel. If push down the gas when starting it works. Once it passes the first 2 -3 seconds everything is fine. No issue idling or driving. What this could be? It's not an issue with Starter, Battery, my best guess would be a sensor, leaky fuel injector.
View 1 RepliesSaturn - SL2 :: 1999 - Engine Rev Up To About 2000 RPMs While At A Stop Then Drop Down To About 650
My '99 Saturn SL2 has from time to time in the past year or so had brief bouts where the engine will suddenly rev up to about 2000rpms while at a stop and/or drop down to about 650rpms combined with surging and stalling while moving. The Service Engine light would typically come on in conjunction with these spells, but then a few days later, things would be back to normal and the light would go off. The episodes seem to correspond with weather that has high humidity, but not necessarily extreme heat. Once or twice when the heat was above 90, the car quit completely and wouldn't restart for several minutes, but that was last summer.
About a month ago the car, which is normally parked in a garage, spent the whole weekend outside when we had some extreme rains (in air temps only about 60s or so). Since that weekend, the car is running frequently with the issues previously described, especially the surging and stalling while driving. It will feel like the timing of the fuel is all out of whack, will shudder and run hard, and then it will suddenly correct itself and run normally. A friend has a code reader and the codes that came up are 404 and 1404, which indicate the EGR valve. We replaced that with a new one and put in 4 new spark plugs, but the problem still persists. I believe the fuel pump is in the gas tank, so from other things I've read, a vapor lock may not be the problem since the fuel is being pushed.
Camry :: 1999 - Engine Dies When Letting Off Gas / RPMs Immediately Drop To 0
I have a 1999 Camry. I just spent $1250 (half of it borrowed) to have some basic maintenance, diagnosis, and serious repair work done. More than half of the serious (translate: expensive) work involved replacing a charcoal canister and installing a thermostat. The check engine light had been on for at least 10 years. And I had a gas pumping problem by way of the pump shutting off after only pumping a few cents worth of gas. Needless to say it was a royal PIA to fuel up my car. As far as the check engine light, a friend would clear the code so I could have it inspected.
Then more than 2 years a shop took out my thermostat because a hose had sprung a leak and they rigged up a temporary hose until they could order the part. I never went back because I couldn't afford it. I know it wouldn't have been a terribly expensive repair, but at the time it was more than I could afford. So for almost 3 years I have driven with out a thermostat and also couldn't get it inspected.
Fortunately I was finally able to get the necessary repair on my car--replacing the charcoal canister and thermostat--so that it could be inspected. I picked the car up yesterday and everything felt fine and the car ran fine.
Today I drove it about 12 miles from my home, made 3 back-to-back errand stops of not more than 15-20 minutes each and everything seemed fine. Nothing felt or sounded out of the ordinary. Then when I was leaving my 3rd stop, the car would not start unless I gave it gas. And it wouldn't stay started unless I gave it gas. In other words, the car would go, but as soon as I would take my foot off the gas to press the brake to put it in gear, the engine would die. There was no problem restarting it as long as I gave it gas, but I could not let off the accelerator at all or it would immediately die.
The car would go just fine, but if I let off the gas for any reason, even if I was driving 40 miles an hour on the street and let up completely off on the accelerator, the rpms would immediately drop to 0 and the engine would immediately die---no noise, no shuttering, no nothing---just die. This problem occurred almost the whole 12 miles back to my home. Then when I got about a mile and a half away, it went back to behaving completely normal and did not die when I let off the gas.
Suburban :: 2003 - Reduced Engine Power / RPMs Drop To Below 1000
IOur 2003 suburban often gets a "reduced engine power" displayed by the computer and the RPMs drop to below 1,000. The vehicle will not accelerate and will not go above 1,200 RPMs no matter how much gas it is getting. Flooring the gas pedal has absolutely no effect and the truck continues on its merry way at about 20 miles per hour.
I have been told by various amateurs that it is the gas lines or electronics that regulate the gas flow. The reduction in engine power seems to happen randomly, but most often if the vehicle is idling for too long (and I'm sure the 110 degree heat doesn't work). I can get it fixed much quicker if I know what the problem may be.

View 6 RepliesHyundai - Sonata :: Full Tank - Engine Starts Then Stall / RPMs Drop To Zero
After I fill my 6 cyl 2004 Hyundai Sonata (280,000 km), the engines starts, then stalls. I can only get it to work by keeping the accelerator pushed to ensure sufficient rpm's. If I remove my foot from the accelerator, the rpm's drop to zero.With the engine revving, I put the car in drive and 'lurch' away from the pump. After that, everything is fine. It starts up properly … until the next fill. My mechanic is mystified and I am frustrated.
View 6 RepliesHonda - Accord :: 1998 - Random Power Loss And RPMs Drop Low Enough For The Engine To Stall
I have a 1998 Accord, 4-cylinder VTEC standard transmission, 226,000 miles. Last fall I first experienced a problem with the car where within 5-10 minutes of starting the engine and driving, the engine seems to lose power/fuel and RPMs act as if they'll drop low enough for the engine to stall. If I take my foot off the accelerator, and reapply, the engine seems to gain power again.
Also, if I open the accelerator to full while the problem is occurring, it can occasionally "push through" and gain power again. Similar things will happen while stopped. In neutral, RPMs fall low and suddenly jump back up and then settle into normal idle. The problem never persists longer than 10 minutes within starting the car.
I took my car into a local shop that came recommended by a friend. They investigated a "check engine" light that didn't explain the problem and were never able to recreate the condition themselves. They replaced a few parts but lost the work order so I don't even know what they changed, but the problem seemed to have solved itself for a while. Recently it started up again and I would love to sort it out.
Ford Ranger / B-Series :: 1987 - Rough Idle And Stumble When Starting Out From A Stop
1987 Ranger and the computer will not communicate. I'm trying to check for codes because of a rough idle and stumble when starting out from a stop. Check engine works but won't flash when using a jumper across the data link. Used a OTC scanner but it only times out and comes up "no data". Where to go from here?
View 7 RepliesCelica :: 2004 1zz-fe - Code P0300 / Rough Idle And Stumble At Low Rpms
I have a 100% stock 2004 Celica GT ~125,000 miles. Over the last few months I have been getting a rough idle and stumble at low rpms. The other day the car would not restart after sitting for about 20 minutes. Only recently has it actually thrown a DTC. The error codes were for misfires (P0300, P0301,P0302,P0303, P0304). I don’t get a code every time but the problem seems to be more noticeable if the car has been ran for a while, sits for 20-30 minutes while in a store and then when I try to start it when I come out of the store is when the problem most often occurs. When it restarts it will stumble at low RPM and if I hit the gas it has little response and misses badly. I have never used a scanner until now. I am using a Autel MS509 scanner and I am not sure it is giving me the correct diagnostic numbers for the live data. I think the DTC are correct but the live data is questionable.
Here is what I have done so far.
- Cleaned IAC valve (completely removed and cleaned)
- Searched for vacuum leaks using carb cleaner
- Cleaned MAF sensor
- Replaced all 4 injectors
- Replaced upstream and downstream O2 sensors
- Replaced Coolant Temp Sensor
- Ensured cam tensioner is providing adequate pressure to the cam chain
- Tried 2 sets of new Iridium NGK plugs and a new set of Bosch Copper plugs
- Moved coil packs around
- New air filter
- New fuel filter
- SeaFoam through intake and gas tank. I have not mixed in the oil.
- Compression Test (1=190,2=190,3=160,4=178)
Things I have not done.
- Taken it to the stealership
- Fuel pressure test
- Valve Clearance
I am concerned about the compression test because according to the service manual it should be around 218. I was using a Harbor Freight compression tester and I am not 100% sure I had a good seal with the tester.
Ford F-150 - 1997-2003 :: RPMs Drop To 330 While Braking
Two weeks ago Sun, truck ran fine, however Mon morning all hell broke loose. Truck was running very sluggish and stalling while coming to a stop. My first thought was tune up. I replaced the plugs and wires. During this I found that i could not get a socket around the ever loved driver side rear plug so i was only able to replace 7 plugs however in that process i managed to break the metal coolant tube that runs to the heater core.
Aday later replaced the entire intake manifold,egr valve, egr tube, IAC valve, both coil packs, fuel filter, tranny fluid and filter. During the removal of the intake i looked at the rear spark plug and found that a screw had been wedged into the hole breaking the plug and got it changed now it is all back together and the truck runs amazing however did not solve the low rpms during stopping. ive replace the above and checked fuel pressure which is good.
I have a TPS sensor just haven't installed it yet not sure if it is related to the issue. Tranny guy says it may be a bad solenoid or TC however last night I reset the PCM and drove it it ran flawless. this morning the problem returned which leads me to believe its not the tranny. ok one last kicker that 6 experts have failed to answer when i manually put the truck into 2nd gear the engine dies! no studder no fighting just quits.
Truck is a 98 F150 4.6 V8 186,000 miles i have yet to
1) change TPS.
2) clean throttle body.
3) clean MAF sensor. n
Not sure if any of this has an effect on the issue. There is only a EGR insufficient Air flow code..
