Chevrolet - 3500 :: 1993 - Truck Starts Surging / Tachometer Jumping From 2000 To 2500 RPMs
Jun 24, 2013
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....

So my 98 f150 xlt 4.6 is having a issue where the truck is jumping from 1500 rpm to about 2500 - 2600 rpm. You know sitting there trying to get up to speed. then all the sudden i look down and its at 1500 rpm. but still not really going anywhere. So i give it a little more throttle or gas and it jumps from 1500 to about 2500. Its been like this for a month but i thought it was crap fuel. What is the cause or maybe a solution?

1997 Chevy C2500 silverado... Ok, so when i go to turn my truck on she'll sit there and chug as it starts. usually a few seconds and then roars up just fine. However I've noticed a couple of distinct things. 1. when it does start i see a second or three of black exhaust come from the tail pipe. 2. if its been started recently. IE within 24 hrs it has problems. but if i leave it over a weekend then the first start has no problems. 3. Last weekend we replaced the Fuel filter and the first few starts there was significantly less problems starting but after 5 starts its back to doing it again.
I checked and the fuel pump does work, I've tried changing the fuel filter ( #2 above), and put sea foam into the gas tank hoping to clean out any gunk in the lines somewhere. It does turn on and when it does it runs great so i know its not having electrical problems as well as the alternator is charging like normal.
Im about to take it in for an oil change and see if that does anything, and I'm praying its not a clog in the Catylitic converter.

So over the last couple of days my GTi has been hesitating as I accelerated past 2500-3500 rpms so I took it in to the dealer this morning to have them look at and sure enough, it had blown an Ignition Coil.
I know this was a common issue with the 1.8l Turbo engines but I thought this had been corrected in the new models.
I have a '10 GTi with 14000 km's on it and some mods (see signature). And no, they didn't comment or ask about the APR chip or intake.

I'll try not to post an entire book.. But I bought a 2000 F250 not even 8 months ago, it did have issues before but I changed out the spark plugs and coils and it fixed it's original missing issues.. I also just recently changed the fuel filter but it didn't fix it's new problem.. It drives ok around town but if I get over 35 mph it doesn't run well... If I try to keep a steady foot on the gas but don't get the RPMs over 2000, the RPMs will stay where they're at for just a second then they will drop down and the whole truck starts shaking.. I push more on the gas and it shakes even more and the RPMs don't move at all until I really step on it.. It lacks in power going up hills as well... The dealership i bought it from said the Catalytic Converter was bad but my uncle who is a mechanic says it isn't.. It's the first vehicle I've bought so kinda wanna make it last..

I have a 2002 Accent 1.6L 72K miles, idle surging between 1500 - 2500 rpm after stopping from 50 mph, (with Code P0121) replaced TPS - No Luck . I reset the DTS error codes, ran it with a new TPS and same exact problem, Code P0121 came back, and surging continued, this happens when I decelerate from high speed- 50 mph or so and it will not go to normal idle, surges between 1500 and 2500 rpm when in park.
If I give the throttle pedal a good kick, the problem goes away, and it idles fine, nice and smooth and at normal rpm, the DTS code will clear, and stays cleared, mil light goes out. It almost seems like something is sticking, I know its not the throttle itself because when I do a live data, the TPS shows "0", if I manually push the throttle shaft closed at the throttle body, it is fully seated shut, so I know its not a sticking cable or anything. Can a sticking MAF sensor cause this? Maybe what I'll try tomorrow is rapping the throttle body with a rubber mallet while its surging, maybe something is not returning to its normal position in there.

My 1995 Chevy Silverado 1-ton diesel stalls with no warning at various times while driving, such as at intersections, on the freeway, coasting, idling. It may go days or weeks without doing it, then all of a sudden stall eight times in one day. My husband says it has sediment, such as rust, in the fuel tank causing it to clog the fuel line. We've replaced the fuel filter twice, and we keep the tank topped off with gas, but it still does this out of the blue at times. I no longer trust the vehicle and will not haul the horse trailer using it, which is why I have the vehicle in the first place. By the way, the problem began after the truck sat for several cold winter months due to drained batteries. After we replaced the batteries to get it running again, it began stalling like this on a semi-regular basis. If it is rust or sediment in the fuel tank, what can we do to fix that? Could it be something else causing the problem?

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.

I have a 1998 Chevy K2500 with a 350 engine. 220,000 miles. It starts fine when cold and drives fine. My problem is when I shut the engine off say to get gas or run into a store. When I return to start the truck it will just crank over as if it is not getting gas. If I pump the gas pedal it will fire up after a bit. It will start to stall if I put it into drive but will recover if I continue to pump the throttle. Once I am under way it drives fine until I make another stop. The check engine light is not on.

I've got a 2008 chev 2500 6.0 liter. This is a intermittent problem. Turn the key "click" nothing happens, try again it starts. Clock sets back to 1200. Chev garage says it's not starter because clock sets back to 1200. Lights will slightly flicker when you step on the brakes. Grounds have been cleaned, battery 1 year old. Ignition switch tumblers working hard. Any guesses. Chev garage cure is run it til it dies.

I have a 97 2500 454 it dies like you trun the key off, but there is still power to turn the engine over but the truck wont start, and after a couple of tries it will start. It might go for a week and not do it or it might go a couple of miles.

I have a 1990 chevy K2500 5.7 350 tbi with 255000 miles on the body and engine. transmission replaced at 200000. When I drive long enough for the truck to get hot (i.e., 10 minutes or so) if i put it in reverse to back into a parking space or my driveway, it just shuts off. i have had fuel filter and fuel pump replaced but what could cause this? it will stay on if I don't drive long enough to get hot.

Mt truck will suddenly die while going down the road. I know it has a oil sensor and wont start or run with oil is low,but recently it just dies in the middle of the road or won't start after a drive of a few miles. After sitting for a few minutes it will usually start. This was happening a couple of times a day until this week when we have had ice and snow, we have been in four wheel drive for four days and it hasn't died or failed to start even once. Whats up with that ?

I have a 97 3/4 ton Chevy truck with 136K miles on it. The problem I have is that the truck is slow to crank when it is warm but when the engine is cool like in the morning or when it has cooled after 2hrs or so the engine turns over fine. I put a new battery in it last summer. I was just wandering could it be my starter.

2000 neon automatic. My wife was complaining about the rpms jumping around when on the highway going about 65mph. The rpms are around 3000 and jump very slightly up and down and you can hear the engine tone change when it happens. Checked tran fluid and it was low about 3/4 of a quart and added some fluid, changed spark plugs and wires and the problem is still there. Doesn't happen all the time. She says it seems to only do this if the car has been sitting for a few hours or longer. There is an code for the downstream sensor which needs to be changed.

When I accelerate (particularly during heavy throttle) I hear a sound that sounds like a diesel engine between 2000 and 2500 rpm's. It almost sounds raspy in nature.

I have a 2000 F250 PSD. When applying the brakes, the rear end starts jumping and bucking. The effect is exaggerated when pulling a trailer and applying the truck brakes to stop. The problem does not occur when manually applying the trailer brakes. It was suggested to me that this problem is caused by a hydro boost leak.

2011 Sonata GDS. I previously purchased 19" Gen coupe wheels and never had a problem immediately. Approximately 2 months later of driving with the 19" wheels, when I got onto the highway one day, the car did a slight jerk with acceleration and the acceleration halted for a split second. Ever since that day, anytime I accelerate fast and/or reach highway speeds, the car has a delay when I hit the throttle. The car then has a "rattle" "groaning" sound that comes when the RPMs hit around 2000-2500 rpm. It will go away if I drive slow speeds/slow RPMs or shut the car off for a short amount of time. I have taken my car to the Hyundai dealer 3 times. I've had the adaptive values for the transmission and engine reset and that didn't do anything. I had a mechanic ride with me in the car to make sure they were hearing the sound and the delay in shifting and the mechanic was very shocked and had never even heard a sound like this before.
