Chevrolet - Kodiak :: 2005 - Surging At Idle
Aug 17, 2014
The truck runs fine and gets the same fuel mileage that it always did and there are no codes...It has the Allison transmission and the Duramax 6.6 and it is a 2005 model C4500 Top Kick capacity 15000lbs. The truck has 254780 miles on it. I can minimize the surging by putting Marvel Mystery Oil in the diesel. Some times it is worst than others ...Sometimes it goes away altogether...Sometimes it will go away if i shift it out of drive at a stoplight.....It happens the worst when I have been at speed for a hundred miles or more or less. Very mysterious...The computer must be sensing a fault and speeding up the idle a hundred rpms .....

When Idling or at low speeds my engine has been surging. When idling it surges with no changes in rpm's but the car shakes and can bee seen and felt. When at low speeds I also get a surge but the rpms will jump up and down. If I drive with the A/C on it cuts the surging down significantly. I had a friend of mine read out the check engine light codes. The are P0010- CAM POS Actuator malfunction, P0011 Cam pos actuator over retarded, C0300 random misfire, C0700 transmission control malfunction. I looked some things up online and they were saying to replace some cam shaft sensors and etc.

I have a 2007 Chev Colorado PU (automatic) and whenever I use the brake to come to a stop my rpms surge from 500 to 1000 - both visually on the tach and you can feel it also. When the truck is stoped it returns to noral (750). accelerates fine - shifts fine - fuel economy is a bit down.

Surging at idle computer check ( at Oreilys) says TPS is faulty. Also using water replaced water pump still leaking. We cannot see any obvious leaks.

Well i have a 1992 for explorer 4.0 all lights seem to dim kinda surging at idle or coming to a stop. Has new battery, battery cables nice and tight new alternator. My Volt gauge on my cluster jumps from 12 to 14 volts. battery light flashes seems to be getting worse. Was having similar issue about 1 year ago found a injector giving up. Replaced injector and worked good for a while. Wondering is it common to have that issue with injectors causing these issues. Doesn't seem likes its missing firing.

Got a problem with my R. 134k miles. About 4 months ago I had similar problems and was told it was a bad MAF. Of course wasn't covered by my warranty, so I decided to just give it a good cleaning and car ran fine up till now. Just started doing the same thing today. Doesn't want to idle, taking off is really hesitant then it just goes. Trans seems like it is struggling to find the correct gear sometimes when coming to a stop or taking off, sometimes jerks hard, maybe throttle position sensor, or idle control? Once you are moving it drives fine, only very low speeds and idling are the problem. Trying to avoid going to the dealership. What this could be? MAF need cleaned again or just replaced?

I have a 2000 Toyota SR5 with a 6-cylinder engine. When I first start the car (cold start) in the morning it will run at high idle (1500-1800 rpm) for about 3-4 minutes. At this point, the idle will begin to drop, but then the engine starts to surge. It's a noticeable surge that bounces from around 900-1100 rpm. It almost seems like an electrical surge, but I don't believe that's the problem. After running the car for a while and it's fully warmed up to operating temperature, the surge goes away. My thoughts automatically went to the IAC (idle air control) or maybe a temp sensor?

My 2001 BMW 325Ci has an occasional "surging" idle problem. When coming to a stop or at idle, the engine will rev between 500 and 1000 rpm's. Sometimes it will correct the problem and idle normally, or keeps surging until it eventually stalls. When restarted it works fine. Tried fuel injector treatment, fuel stabilizer treatment, and replaced thermostat. Still surges about 50% of the time. Had it to a dealer, and computer says its running fine.

I am having great difficulty trying to figure out why my truck is surging so bad in park or in gear at idle. I have to mat the brake while in drive to prevent me from ramming the car in front of me. It all started when I replaced the air filter. Everything I've read leads me to the EGR valve, but that has been bypassed.

My son bout his first truck yesterday. 98 ranger sc 4x4 auto 4.0. Beautiful shape 139000 miles. got it cheap as it has issues. its been parked for a year. It has a surging idle when you start it up. rev it to 2500-3000 rpm and it idles fine turn it off and restart it surges again until you rev it. When we test drove it it ran like it was running out of gas/bad fuel pump, sputter at full throttle but accelerate at part throttle. Gauge said under 1/4 tank of gas. We put 3 gallons of gas in it when we got home and it seems to run fine now other than the idle surge. it had a 174 code(lean bank) but if it was running out of gas it should pull a lean code right? I am thinking IAC or intake leak.

I just notice this problem after I bought this used 05 Camry I4. When I was running at a mild speed said 30-40 miles, the engine will accelerate by itself and the RMP will jump to around 3000-4000 instantly with a pretty loud noise like you are stepping on gas while stay at N gear and the speed won't go up a little bit. The problem seems won't cause much impacts on driving since the RMP will drop to normal very quickly and such thing only happen occasionally. After doing some search online, I really don't know what kind of problem it is, I did check my transmission fluid lever and found it is in normal area.

Mechanics say they don’t know what wrong… I had some transmission work done on my truck – mostly an leak and replacing the harness – and ever since then after it rains or if we have a heavy dew my truck does the following:
Driving from O to 49 miles an hour truck is fine, as soon as I hit 50 the truck starts surging and you can see the tachometer jumping from 2000 RPM to 2500 RPMs. I drive around 17 miles to work where my truck will sit for seven hours. On the way home the truck is fine. I find this to be more of a problem when the truck has sat for a day or two over the weekend without driving it. Sometimes the “check engine” light will come on, sometimes not.
I have taken it to two different places and neither one says they can find anything wrong with the truck. I have driven this truck for over 11 years and know it very well. There is something wrong, but what? 1993 Chevy Silverado 3500 Diesel....

I have a 1998 Crown Vic Lx with 66,000 miles on it. We bought the car about 2 years ago and at that time it had only 32,000 original miles and looked like it had just rolled off the showroom floor. The car was well maintained and we have kept it that way. Over the last few months we have started to have a problem with the engine surging at idle when the Heating/air controls are in use. It's like the engine tries to die and then comes back up and it happens about every 5 seconds. It stops when the control is cut off. The fan speed control has no effect,just the main control.

I recently cleaned the throttle body and now it surges up and down. Not really sure what to check next. 2002 toyota camry 4 cyl.

My 2002 F150 (50,000 miles) 4.2 is surging when cold. I just got done replacing the pcv valve. I noticed it was running better so I cleared the service engine light, but now is surging when the engine is cold. I live in FL so it does not get that cold like up north. The following codes were the ones that the pcu put out, P1131, P1115, P0174 and P0171. I am leaning towards changing the IAC valve and maybe the oxygen sensors.

I'm having trouble with my ford ranger. It cold starts fine, and drives fine while cold. Once it warms up the idle is barely keeping it running, or surging 1000-1500 rpms above normal idle. Any gas I apply while hot idling will stall out the motor, and will not restart. It acts like it is very flooded when I try to do a hot start. I pulled the IAC valve off and cleaned it even though it was very clean and actuated properly. I also cleaned my MAF, and that changed nothing. I really do not want to just throw parts at it hoping I guess right before I'm broke. Not sure where to go from here, and I live in Alaska where I am fixing this outside.

The vehicle I am working on is a 2005 Camry LE with the 2.4L I4 with 172,000 miles. The problem is it surges under acceleration or when the tranny downshifts and engine is under load going up a hill.car idles fine and runs good otherwise. Its hard to explain the surging without driving it yourself but I will tell what I have done so far and car is not showing CEL.
-replaced the AFR sensor (Bosch)
-replaced the O2 sensor (denso)
- plugs look good (no fouling)
I am thinking maybe the throttle position sensor or MAF sensor. What to check next.

Drove 28mi out to dinner and when leaving after, she wouldn't start. Took it to work in the morning, and it ran fine prior to that. It was 15degrees outside, added heat to the gastank thinking the fuel line was frozen. Tryed to fire on, but it would only idle briefly surging while doing so and die, like not enough gas. It did start after I held the key down during this surging process grinding the starter also, should have driven home, but I shut it off like a idiot, as a result, had to tow home. Noticed TCS OFF light was lite up while it was running, then I shut it off, TCS OFF LIGHT went away when I turned key back on to attempt a 2nd restart. After i did that, it wouldn't fire on again. Towed to my house, I do not hear the fuel pump trying to kick on when i turn on the key. Fuel system is dry. Cranked over next day and definitely no gas in the lines. Bled the fuel system, no fuel shot out. Have checked the fuse box and the one under the hood too. Replaced the fuel pump relay but still no go just (this blows)...

2004 Santa Fe .... 2.7 6 Cyl 4WD 150k miles
Recently I started experiencing RPMs surging upon startup and driving before my engine warms up. The problem has gotten worse to where I push on the accelerator the RPMs jump to 2700 and the transmission feels like it disengages. My initial thought was the tranny was going bad and slipping. I checked the fluid level in the T and found it was maybe a half Qt. low. I topped it off, but this had no impact on the problem. On a side note, I am able to use the manual shifting feature on the "His and Hers" Shifter and drive the vehicle without any issue. Transmission works fine in manual. The surging RPMs which only occur in Automatic mode, triggered the CEL and I got a code of P0123 which is high side voltage on the Throttle Position Sensor. I replaced the gray TPS with a new black one.
Upon startup the RPMS jumped to 3000 just sitting in Park. I disassembled and reinstalled figuring I had something bound in the throttle. After reassembly the idle went up to 2200, still no good! I reinstalled the original gray TPS and the RPMs, upon starting, RPMs were 1500 with the old sensor...still too high. I did reset the ECU twice during the process of putting in the new sensor and reinstalling the old sensor. Right now I found that when I disconnect the TPS electrical connector, the engine runs normal. It starts right up with the TPS totally disconnected and idles at 750 RPMs! It will not shift to 2nd gear though, when I try to drive it in Automatic Mode. I can however drive in Manual Mode and drive normal and shift right through the gears. Who needs automatic mode right?!!!

Having some problems with my 92 Nissan NX2000. i just finished changing the clutch on the car now its acting horrible.
When i start the car, it will run decent for like 2 or 3 seconds then the idle drops down till it almost dies, catches itself, idle goes up to about 500 were it will pulse around for a few seconds until it dies. If i rev it it will stay running, kept it running for about 2 mins. but as soon as i let off it will pulse at 500 until it dies
After i changed the clutch it started up fine, it ran great for about 20 seconds before it just died. when i started it after is when the problem arose.
I took a video of the car running, which can be seen here. [URL] .... (It has never caught itself like that before and jumped up to 1000 rpms before. It normally will die at that point)
The video is really quiet, not sure what happened there. if need be i can get a video of the engine bay so its louder, was mainly focused on the RPMs.
Here's a few things i tried: Checked fuses, Changed spark plug wires, made sure they were all seated good, MAF wires were rubbed a bit so i cut the MAF pigtail off one of my other sentras and soldered it on,Changed to a good battery, Changed fuel filter, Added more gas (in cause gauge is broken), Made sure all connectors are plugged in, Checked around for vacuum leaks, found that one of the large hoses coming off the intake going to the engine had separated so i plugged them back in and nothing.

I replaced the exhaust back pressure sensor and the readings on my sct programmer didn't change at all so I don't want to keep blindly throwing money at it if one of you has experienced this and found a cure. The interesting thing is it never throws a code or check engine light or anything according to my sct. Doesn't even show that the egr valve is unplugged. I have read that it could be a bad turbo, vgt solenoid, icp, throttle positioning sensor, or a couple other things.
It feels like I'm the front car in a bump draft in cup racing when I'm at a steady speed. The truck has arp head studs, new style egr cooler with the tubes, coolant filtration, new oil cooler, new ficm, blue spring, all filters have been changed in the last month.
