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.
Nissan - 300zx :: Engine Surge At Highway Speeds For Several Seconds Then Drops Back Down To Normal
my 1990 Nissan 300zx with 136,000 miles often surges at highway speeds for several seconds then drops back down to normal. the surge is usually 1000 rpm. does not happen if not in overdrive, and will not happen unless having been driving for 15 minutes or so. also seems to occur more on hot days (80 degree +) than on cool days. mechanic has looked at this several times but not yet able to determine why.

I have a 1999 F350 200,000 miles. Now getting an intermittent engine light. Still runs well, although once or twice I felt a momentary surge at highway speeds. The light is on intermittently about 1/2 time. I read the codes and the following codes, as in the thread title, came up:
P0280 - ICP circuit out of range - low
P0113 - intake air temp sensor circuit - high input
P0470 - Exhaust back pressure sensor circuit malfunction
P0478 - Exhaust pressure control valve - high input
What would make these all code at the same time? Would these not make a noticeable problem driving? And how do I resolve these?
Silverado :: 2000 / 5.3L Engine - Vibration At Highway Speeds Between 40 And 65mph
I recently got a used 2000 silverado 1500 ext. cab with a short bed. Has a 5.3L engine. I noticed it has vibrations at highway speeds. I thought it was the crappy tires on it so I had all the tires replaced and balanced. Now it has all new tires and does the same thing. Runs really smooth all the way up to 40mph and then the vibrations begins. It is mostly felt in the steering/dash and pedals. A little more pronounced on accel. but vibrates if your on the gas on not.
Once your reach 65mph, the vibrations stop. I have also noticed that asphalt makes it vibrates more. When I go over concrete overpasses in the problem area of 40 to 65mph it smooths out. I took a look under the truck and saw nothing obvious. U joints feel tight and no play, seen it had weights which appeared welded onto the one piece drive shaft.
Silverado :: 2001 2500HD 8.1 L - Every Once In A While Engine Just Quit While Driving
My crew cab 2001 has 75K miles and is well maintained and garaged. Every once in a while the engine will just quit while driving just as if the key was turned to neutral all dash indicators light up but just quits running. Turn the key to start and hear the engine cranking but won't start. Sometime in park it just cranks however I noticed that when I move the shift lever into neutral and depress the brake it will crank and start sometimes.
I don't believe it's a fuel problem. Could it be a loose wire in the column?
Silverado :: Engine Power Randomly Reduce During Driving - P1516 Code Returned
Truck is a 2003 1500HD Silverado with the 6.0L 364V8. Last winter I started getting the P1516 code and reduced engine power randomly during driving. After dealing with it for about a month I did some research and discovered in most cases it was either the wiring/plug or the TAC module itself. After going over the connections I couldn't see any visible breaks..etc but I decided to go ahead and change out the connector and about 6inches of the wiring.
After replacement the code hadn't come back until today, probably atleast 9months ago was the last time it did it. Today the code came on four times during a 10minute drive. Before it would come on once during the drive, i'd clear it with my scan gauge, and it would not do it again the entire day. I checked all my connections once again and everything is intact and there is no visible breaks and the connector is clean. I'm starting to think that it was just a coincidence that this problem quit when I replaced the connector, and was wondering if colder weather could have weight on this issue?
After poking around the posts on here and other sites I found that many ended up replacing the TAC module which is on the throttle body. After looking at mine the only way I can see replacing that is just buying a new throttle body with the TAC on it, can't seem to find just the TAC part by itself anywhere. So if I were to order a new throttle body how hard is it to remove/install? and do I have to do a relearn process or is it plug and play?
Silverado :: 1993 - No OD At Highway Speeds
I have a 1993 3500 Silverado that goes thru all the gears until it gets to the OD but will not go into OD at highway speeds,does not slip as it is shifting, why this is happening. Could it be that all it needs is a fluid & filter change as that is what it needs done now.

Driving down the highway today, my car just all of a sudden quit. I had it towed home, and checked the spark and fuel pump. It turns over fine, there's plenty of spark, and the fuel pump works great, but I don't think fuel is getting all the way to the engine. Could the fuel line be blocked or something? Maybe the injectors?
View 3 RepliesElantra GD (2013+) :: Check Engine Light Came On When Driving Down The Highway
I just purchased a 2013 Elantra GT, 3 days ago. I was driving down the highway and my check engine light came on. There is only 480 miles on my car! I know it's not a gas cap. I haven't even put gas in it since I drove it off the lot. Is there a way to check for the code thrown without a scanner? I use to have a jeep liberty and I could click the key over 3 times an the code would pop up.

03 v6, xle. 125,000 or so.
On highway, mostly notice with cruise on, what seems like engine shake starts. Almost like engine is moving around a bit. There is a noticeable "jump" sometimes, when going up or down hill and the cruise wants to adjust speed.
Nissan :: Check Engine Light Came On Only When Driving At Highway Speed
My truck is a 1997 nissan pickup with. 254,000 miles. Check engine light come on. Only when I am at highway speed. As long as I am in city traffic, nothing I have a code scanner code (PO302) number 2 cylinder misfiring. I change spark plugs and wires and dist cap. But check engine light came back on. I put in shop they claim that they can't find nothing wrong. I guess I need to find a new mechanic.
View 3 RepliesToyota - Corolla :: 1995 DX - Engine Just Stopped While Driving On Highway Then Would Not Turn Over
The car's engine just stopped while driving on highway, then would not turn over, nothing.Took for repair, said battery had bad cell or something, still under warranty, replaced.Fixed a few other things that were overdue, spark plugs, wires.
Okay. Next day, took the car on a few city driving short trips. While going across town on hot 85 degree day w/ ac on, it died again. Don't remember any lights coming on, didn't last time either. I think the AC died first then car died. Wouldn't make a peep. Right in middle of heavy traffic. When police came couldn't even steer. There might have been a slight weird noise which I thought was the ac making trouble right before it stopped, can't describe it really.
Had it hauled to shop again. It runs fine for them so far. They are still working on it.What in heck could it be? All belts were replaced a few years ago, car has always run well, never any major repairs just maintenance. It has about 133,000 miles on it. It has a clutch.
Ford - Ranger :: 2000 XLT V6 Quit While Driving On Highway / Engine Is Blown
My 2000 Ford Ranger XLT 4x4 (139,XXX miles) V6 3.0, recently quit on me while driving on the highway. It will no longer start. I spoke to a mechanic and he informed me to fill the radiator (which was empty) and attempt to start the truck with the radiator cap off. He said that if radiator fluid gushed out then the engine is blown. Is this necessarily the only cause, that my engine is in fact blown.
View 19 RepliesElantra XD (2001-06) :: Engine Surging On Highway When Driving At Constant Speed
I have an 04 Elantra GT and have been noticing a jerkiness when driving at a constant speed on the highway. I haven't noticed it around town or while accelerating. I also have noticed that when I disengage the clutch on the highway, the engine sometimes doesn't respond right away, or it even may surge. This has happened when exiting the highway when I disengage the clutch. The engine will slow, then speed up close to 3000 rpms.
I also had a check engine light come on and couple months ago. The code indicated that the upstream O2 sensor was bad. I took it out and cleaned it, but didn't replace it. Is this a likely culprit for this set of symptoms? If so, how can I test the sensor to be sure? I heard that I could disconnect it and run the car and see if the surging lessens, but wasn't sure if that was a good thing to do.
Chrysler - Sebring :: 2002 - Check Engine Light Came Driving Down The Highway At About 70 MPH
I drive a 2002 Chrysler Sebring convertible with about 130,000 miles on it.
I was driving down the highway in early November when the check engine light came on my car. I took it to Aamco who did some diagnosis and replaced a solenoid assembly in the transmission. The light went off and I was on my way. I never got the exact code.
About a month after that, the light came on again. This time, I got a low end code reader and scanned it myself. I got a "P0700" code, which I've read is a generic code that the transmission system sends to the computer or something. So I used my reader to erase it. However, the light came on 2 days later while I was driving down the highway at about 70 MPH.
So I went to an auto parts store to get a more detailed scan with a better tool. This one came up "P0740 Torque Converter Clutch Solenoid Circuit".
This feels weird, because the solenoid assembly was just replaced a month ago (and is still under warranty).
The car seems to drive okay. I don't notice any actual problems in shifting. The tachometer seemed to get up to about 3000 RPM on the highway. But I've seen practically new cars do that. The last time I had serious transmission problem it would rev up to about 5000 or 6000 RPM on the highway and still only getting up to about 40 MPH. That was 3 years ago and at the time I had a fairly expensive transmission repair (which included a new torque converter).
But like I said, the car seems to be driving okay. I don't drive much. Maybe 100 miles a week? And even that is mostly optional in town driving. I'm not looking to keep this car for more than another 20,000 to 25,000 miles though for the time being I cannot afford a new one.
What are the possible causes here? What are the consequences of ignoring this? Like I said, it's still driving fine and as the old saying goes "if it's not broke, don't fix it".
Landrover - Discovery :: 1998 - Loses Engine Power While Driving On Highway
1998 discovery. Replaced fuel pump, crank shaft sensor, battery is good, had tune -up. Driving on highway and car just loses engine power, still have radio, lights, etc. Pull over and start it right back up. Drive about 15 minutes more and it happens again. Starts again. Then it does it again, but now won't start. Clicking sound in dash on passenger side. I leave it sit for 2 days. Starts right up, then rpms start revving then stops and dies. I have had every diagnostic known run, no codes coming up. I have had local mechanic keep it for days to drive it. He is also at a loss. I am REALLY tired of replacing random parts to no avail. Not to mention the $$ I have spent.
View 7 RepliesSaturn - Vue-hybrid :: Died While Driving On Highway - Different Engine Lights Started Coming On
My 2007 Saturn Vue Hybrid died on Sunday while driving down the highway. The car has 101,500 miles and a brand new (November) battery. It was -5 degrees out at the time. Different engine lights started coming on, one at a time (the check engine light, the traction control light, the oil change light, then the seatbelt light) and then all of a sudden the entire dashboard went dark and the driving lights went out (it was close to sunset so we had the lights on). My fiance barely managed to steer the car over to the shoulder before it completely died. The hazard lights wouldn't even worked. My mechanic got it jump started yesterday and was able to drive it and said no engine lights are on, and everything looks fine. He does not think it was the alternator. What this could be?
View 8 RepliesVenture :: 1999 Engine Low Idle And Stalls When Stopped / Parked After Driving On Highway
I have a 1999 Venture Van. The engine has a low idle and stalls when stopped/parked after driving on the highway for 10 minutes or longer. Whenever I drive it to the train station in the morning to go to work, it dies as soon as I park it. It will start up again fine right away tho. I drive 10 minutes on the highway.
The engine light is on, but goes off sometimes for months before coming on again. I've brought it to at least 3 mechanics and they can't get the light to stay permanently off, and say to just drive as-is. But that still leaves me with the low idling problem. It doesn't always stall, but the potential is always there, as you can hear the low rpms threatening, and dread stopping at a light.
I had the engine light interpreted as P0122 TP SENSOR CIRCUIT LOW. The mechanic replaced the Throttle Positioning Sensor. Engine light came on again 2010. Mechanic did a Computer system check/smoke test. Diagnosed a Leak in evap system so they installed a new gas cap and vent valve. 2 months later, engine light went on again.
New plugs, spark wires, fuel filter, fuel treatment, fuel line, gas cap, vent valve.
1 month later light is on again, and low idling persists. I put alot of $ into the problem with no solution. Some mechanics say the engine light has no relation to the low idling.
Wife wants me to get rid of it, but the Van is in great condition except the low idling/stalling problem. I don't care if the light stays on, as long as the low idling/stalling stops. Can't I just ask a mechanic to increase the idling rpm?
Volkswagen :: 2004 Golf Yellow Check Engine Light Comes On When Driving On Highway
2004 Golf, manual transmission. The yellow check engine light comes on when it's driven on the highway for more than 10 miles or so (60-70 mph).
The light goes off on it's own after about 36 hours of suburb driving - 1-2 miles at a time on suburb roads, lots of lights and not going over 40 mph.
1) Why the light is coming on? No other signs of trouble occur - oil looks good, temp stays fine, no smells, etc.
2) Why the light goes off after 4-6 miles/36hours?
