Silverado :: 2003 With 4.8 Engine - Idle Surge And Stall When Cold
I have a 2003 silverado with a 4.8 engine. i bought the truck in the summer of 2010. no problems in the winter of 2010. ran great all year in 2011, then my block heater shorted out in the winter of 2011, so i wasn't able to plug the truck in.
We get some cold nights up her in alberta, but anything below -10c the truck would idle surge and stall, would do this about 4 times in a row then it would just surge a few times but stay running.
I had a buddy that's a gm drive ability tech take the truck and do a tone of updates for the throttle body and to correct idle surge and some other drive ability related stuff. i cleaned the maf, map and tps as well as the throttle plates. replaced plugs, wires, air filter and fuel filter. all this and it was still doing it, but it had to be really cold to stall.
wasn't able to replace the block heater till this summer. but now that its getting colder and dropping below -10c at night the truck is starting to idle surge when i start it up in the morning.
Passat (B5) :: 2002 1.8T - Idle Will Drop And The Car Will Stall Out When Driving
I have a 2002 passat. It is a 1.8T. I have a stock turbo, it has a full aftermarket front mount hooked up. It also has a blow off valve. OK my issue is that I believe it runs too rich. When I drive the idle will drop and the car will stall out. It has its good days and bad days. What can I do to make this not happen? Would I have to have a recirculate the air flow again? Should I have everything stock again? Would anything else stop this happening? As well as how much PSI does this car stock suss posed to push? I have a boost meter that only reads max 5 psi. Should it be more? I am new to VW and brought the car off a friend.
View 17 RepliesFord 6.0L Power Stroke Diesel :: 2003 - Surge At Idle After Driving For A While
My 2003 6.0 has started to surge at idle after driving for awhile. Like when I drive to work (30 min) and pull off the interstate the idle will bounce around at the stop sign (only jumping like ~100rpm). Does this sound like the ICP to you? I've replaced it once before and am wondering if it's time to do it again?
Also the truck will sometime be hard to start. And when I say hard to start I mean turn the key, let the GP cycle the turn to start and it just cranks. But as soon as I turn the key back off and cycle the plugs again it'll fire right up. It doesn't seem to matter if it's hot or cold. It's been doing it since I got the truck. It seemed to get better after the 1st ICP but didn't completely get fixed.
Passat (B5) :: Low Idle Surge, Stalls When Coming To A Stop
Just purchased a 99 passat v6 and it has a low idle surge and stalls when coming to a stop.It runs fine until it heats up about 15 min. then it surges up and down and stalls.
View 1 RepliesPassat (B6) :: 2007 2.0T CEL On / Surge At Idle And Whistle Or Squeal When Moving
The title pretty much explains it. Coming home today started hearing a squeal/whistle while at highway speed - almost sounds like the brake wear indicator tabs that GM is so fond of. Thought it might be the brakes, but it didn't stop with brake application and continued after coming to a full stop. Also, surging at idle, which seems to be reduced when the A/C compressor is on. The squeal happens both with and without A/C.
View 1 RepliesStalling - Chrysler :: 1999 Cirrus Would Randomly Stall When Driving Or While In Idle
I started having problems with my '99 Cirrus last month, it would randomly stall while driving or while in idle. With no check engine light or any other tell tale signs of a problem. I'm not entirely knowledgeable about how the entirety of the car's systems function, though I new I should check my fuel system. I wasn't getting any fuel to the engine whatsoever, so I replaced the fuel filter because when I got it off and looked at it it was clear it was bad. Then I put it all back together to try and run it and it continued to stall.
Thinking it must be the fuel pump at this point I dropped the fuel tank and replaced it. It ran for about 35 miles before the same problem started happening again. So I checked all the fuses, and relays and just to be safe replaced all the relays related to the fuel pump, and fuel system and i even replaced the auto shutdown relay. The car continued to have the same problem, so I did some research and found out it could be a dirty throttle body so I cleaned it even though it wasn't that dirty, and checked my air filter for how clean it was and it was clean. The car still continues to stall in idle and while driving.
Spider - Alfaromeo :: 1990 - Blip At Idle / Engine Would Sometimes Stall While Driving
I have a 1990 Alfa spider. It has a blip at idle. Originally it was much worse. Idle would drop to 500 then pop up to 1200 the back down, back up etc. Engine would sometimes stall while driving. This happened as I would take my foot off the gas coming to a stop. I replaced the first large air duct between the mass air flow gauge and the air intake chamber(cracked on underside). Worked but still had blip which was then unpredictable. I cleaned the air flow gauge and the constant idle actuator with air flow cleaner. This worked more but I still have the blip during engine warmup. Idles fine at start up, blips for a while, then stops bliping as engine nears running temperature. What should I do next?
View 1 RepliesFord F-150 - 1997-2003 :: Surge Or Stall Out When Slow Down Sometimes
I have a 97 F150 with a 4.2. It has started to surge or stall out when I slow down sometimes. It doesn't do this all the time. I replaced the fuel filter about 2 mths ago and replaced the fuel pressure regulator then also. Would the tps have anything to do with it? I haven't had a scan done yet. Thought I would try here first because at one time someone has removed the two cats and the check engine is on all the time.
View 4 RepliesPassat (B5) :: Rough Idle - Shudders Like Going To Stall
My car started a rough idle last night.... Pull to stop light, in gear, a/c on #1 and car shudders and acts like it's going to stall..... Went away as I drove a round a bit.....back this a.m. (after the warm up program ran) drove it a bit and was sporadic.....and even went away...then came back.....
Its worse when car is at stop and in 'D'.....little better with a/c off and/or in neutral......it finally threw the CEL today....... I had the fuel pump recall done about a month or two ago, car has 36k+ on it...... Anything I should have the service dept look for aside from what the fault codes might read?

Ford Super Duty (1999-2016) :: 2005 - Surge And Stall When AC Comes On / Gas Pedal Disables
I have a 2005 f252 6.0 diesel with electronic climate control and when my a/c comes on it surges/stalls my truck and throws several codes (P0108, 0403, 0405, 2104, 2123, 2138, 2139, 2140) and disables my gas pedal. I know I am loosing my 5v reference, but not sure where. I have replaced my compressor, alternator, both batteries, low pressure switch, accumulator, oriface tube.
I've disconnected several 5 v reference sensors and all gives me the same results. if I disconnect my low pressure switch my defrost and heater works fine and no issues, but this is not engaging my compressor. when I plug the low pressure switch back in , the same issues happen, I checked my fuses, and swapped the relay in the battery box. Looking for drawings of the circuitry or wiring diagrams.
Celica :: 1992 2.2 - Idle Surge Between 500 To 750 Rpm
My 1992 Toyota, Celica had developed a really weird idle surge. The idle surges between 500 to 750 rpm. The surge goes away with the AC on and it idles steady at 900 Rpm. It also has a slight off idle bog that may just be another symptom of the weird idle.
I did the diagnostic test today and it doesn't flash any codes. I pulled the EGR valve off and cleaned the gunk out of it and it didn't make any difference. I tried to check the timing and it idles so bad the timing bounces 7-10 degrees with the surge. When I did the jumper to check the timing it would kill the engine. The plugs and wires are new with in a couple thousand miles. It runs fine above idle and pulls to redline easily in the lower gears.
Yesterday when I was messing with it I had the car running with the air boot from the air cleaner to throttle body off. I sprayed carb cleaner into throttle body and it seems to clear up a little bit. Then it went back to surging again.
I tried to pull the TPS off yesterday and of course the bottom screw stripped out. Now I will have to pull the throttle body off to get the screw out. I wish it would throw a code so I could have it give me a clue.
Lumina :: 1990 3.1 - Idle Surge After It Warms Up
My 90 lumina euro 3.1 has idle surge after it warms up. fluctuates between 600 and 1200 rpm when in drive. When you first get on the throttle it wants to die. Once you get past that it runs smooth while driving. Ive also notice that it tries to "buck" when its at lower rpm and barely on the throttle while pulling.
I can't seem to find any vacuum leaks, has recient tuneup, had a egr code and that has been replaced. I've cleaned the throttle body also. Previous owner had intake gaskets replaced as well as fuel injectors, fuel rail, fuel pump.
Honda - Cr-v :: 2000 - Idle Surge That Just Won't Quit
have a 2000 Honda CR-V with a B20Z2 engine and automatic tranny. This Honda has an idle surge that just won't quit!! (surge= rpms rise and fall, repeat) It's really driving me nuts and I need this car to drive for school next week! So far, I've:
-cleaned throttle body
-replaced spark plug wires (plugs are fairly new), distributor rotor, and distributor cap
-bleed coolant
-ECU relearn idle
-adjusted intake and exhaust valves (tight exhaust valves are incredibly common on my engine)
-cleaned out Idle Air Control Valve with Simple Green
-performed vacuum test (with propane, not carb cleaner since it works the same)
-performed compression test (every cylinder checked out)
-replaced throttle body gasket
I've had Check Engine Light misfire codes for a while now, but they pretty much disappeared after the valve job. All that's left is an Idle Air Control System code (P0505). I'm am completely stumped at what to do now. What's more is that white smoke has started pouring out of the tailpipe and it doesn't smell like coolant. At first I thought it was the oil in the cylinders from the compression test, but now I'm not sure. It doesn't really smell like oil or coolant, but it smells like something is burning....
Sierra :: GMC TPS Sensor - Idle Surge / Low Engine Power
My truck has been having idle surge, low engine power, says stable tracks is off, computer said TPS pedal sensor. I replaced it. Within 3-4 days my truck does the same thing. I turn it off and eventually my truck runs fine with the exception of my engine light is on truck runs good. I put the computer on it again while the truck running bad and it continues to say it is the TPS sensor.
View 2 RepliesSanta Fe (CM - 2007-12) :: Surge Only At Idle Speeds About 200 Rpms
I have a 2008 Hyundai Santa Fe. Has about 65k miles on it and has regular maintenance and tune ups when needed. It is cared for. The last tune up was about 2k miles ago. Spark plug change, oil change, filters, etc.
I have noticed lately that when the car is moving at idle speeds, it will surge about 200 rpms. It does not happen when the breaks are on or stopped or in park, or moving at higher speeds. It only does it while moving and with no acceleration. It happens in Drive and Reverse.
I live in the city of Lima Peru so a 4x4 is useful but it also requires some tight parking but when it starts to surge, it is a huge pain.
Ford Ranger / B-Series :: Idle Surge On Startup
On startup, hot or cold, I get an initial high idle, up to around 1800 rpm's. This happens immediately when engine starts, and then idles right down. This has done this since new in '04. Dealer at that time said it was normal and not to worry. It's always made me wonder, but I trusted the dealer. Ya, not always smart.
After 92k miles. Engine runs fine otherwise, but I don't really care for grabbing a bunch of rpm's on any engine without having the oil pressure up to normal.
A few weeks ago, I started it up, and some yahoo said he knew I drove big trucks by the way I started my Ranger. That was one of those times. I'm thinking IAC is wide open maybe?
Silverado :: Engine Surge When Driving Down The Highway

Usually between 40 and 50 MPH. if i let off the throttle it will smooth out or if I give it more throttle it will smooth out. What would cause this??
View 2 RepliesDurango :: 2000 - Shudders On Shifting Gear / Surge A Little At Idle
I recently purchased a 2000 Durango with 151K on the clock. It looks like it was well taken care of, clean inside and out, and runs/drives nice. I just have 2 "concerns". There are times when the vehicles shifts from 1-2 and 2-3 it "shudders", only does it for a split second, and seems mainly when pulling out on some sort of upgrade, but not always. Otherwise it runs and shifts fine.
The second "concern" is that it seems to surge a little at idle. At a warm idle in park is when I noticed it. It goes from about 750 rpm to 950 rpm over and over. I haven't really noticed if it does it during regular driving.
Santa Fe (CM - 2007-12) :: Motor Will Rev Up When Cold / Drop To Low Idle Then Surge Up Again
My 2009 with the 3.3 motor will rev up when cold drop to a low idle then surge up again. It will do this until it is warm even when in drive. It never did this before only in the winter it would start at fast idle for a minute then drop to normal idle. There are no codes or lights, what would cause this?
