So I used my 2000 silverado 1500 to remove a willow trunk from my yard. 4 Lo, took a bit of work but I tried not to overdo it. Now, truck sputters when accelerating. Once it gets going it's good but the startup is sputtery and bucks a little. What did I do?

When cold you have to feather gas pedal to truck accelerating, you can hear truck motor pop through throttle body but will continue to speed up.
View 2 RepliesSix months ago we purchased a '91 Chevy Pickup and 3 months ago the truck started to "sneeze". Sometimes while accelerating the truck makes a "toot" noise from in front of the driver under the hood, and with the noise I have a momentary loss of RPMs. This can happen a number of times in a row, making pulling out on to busy streets difficult and dangerous. Most of the time, I take my foot completely off the gas and then re-apply it, and the issue goes away. It happens both with a cold engine and a warm/hot engine. This problem started when it was cold out (around 10 degrees Fahrenheit) and the mechanic I talked to about it thought it was the E10 87 gas I was putting in.
I switched to a 97 octane/no-ethenol fuel and the problem went away, until about a week ago when our temperatures finally broke 50 consistently. The problem is back and with it is a minor fluctuation of RPM when idling in neutral. The truck also created a new symptom, I was driving at about 50mph and the truck acted like it slipped on ice... I had evened out my speed and the truck seemed to start coasting then got back to driving at speed, it jerked the whole truck, like driving over a patch of ice. I don't know if it has anything to do with the original problem but all symptoms may be the same thing....
The truck is a 91 Chevy 1500K, 5.7L V8 and has 74,000 miles (mostly highway towing). It had been sitting 2 years, not really being used, before we bought it. We had the fuel injection system cleaned when they did the oil change, right after we purchased the vehicle.
My 02 silverado has started making a bubbling sound when I accelerate. The sound is coming from under the passenger side dash.

View 7 RepliesMy 1990 Chevy Silverado with 5.0 liter, 45k miles has started a problem that the guys in my diesel repair shop don't know what to do. Last week it started to run rough, hesitating and lurching and not accelerating smoothly. It idles fine, or pretty well, but just doesn't run smoothly with any kind of acceleration. I drive it back and forth to work just 1.5 miles during the week. I took it on vacation a week before, so it's not from lack of long trips, it ran fine.
A guy at my diesel repair shop put it on his Genesis scope and all it would code is the O2 sensor showed lean, but we could see it switching from rich to lean and so on. I thought vacuum leak, but couldn't find one. PCV valve is good. EGR valve is ok. I changed the fuel filter yesterday and thought it ran a little better, but now has gone back to the rough running. What I can do myself to diagnose this? I do have all the tools and shop.
I have a '96 Chevy Silverado that twice (in about as many months) has had some trouble starting. When I turn the key the engine starts to crank, then there is a loud pop and the engine stops. When I crank it again the engine will start, although more slowly than usual. What could be wrong?
View 19 RepliesMy 1995 chevy c1500 cuts out at idle or the moment the brakes are applied to shift into drive. I replaced the passenger wheel cylinder and bled the brakes and it ran fine for a few hours, then the idle problem stated again. I have check the map senor and a few other electronic component as my mechanic said the problem " might be electrical."

View 1 Repliesi have a 1982 chevy 1500 4x4 with a 700R4 and it has never give me any problems at all has always shifted firm and smooth goes instantly in to drive and reverse. One day last week i got in and the truck will not shift in to second actually wont come out of first the reverse still works fine and the first is still fine it does not slip or hesitate at all. I pulled the gear cover off and can spin it!
View 8 RepliesMy truck hasn't run for over a year and no one seems to be able to tell me why. The fuel pump supposedly has 10 lbs of pressure, it has new fuel pump relay, new throttle body, and probably more new things (can't remember exactly). It will start up normally and then it will act like it's not getting fuel and within seconds die. If I keep my foot on the gas and kind of pump it (I know it's EFI) it will try to keep running, but will die, and it really gets rough toward the end like the whole engine's going to fall out. The truck has 300K+ on it but the engine was replaced about 10,000 miles ago. It still has a lot of original equipment.
View 14 RepliesMy truck just recently started to vibrate like it is going over rumble strips. It only happens over 40MPH and sporadically. It seems to happen when I'm just giving enough gas to maintain speed. Once it starts if I let off the gas or give it more gas it goes away. It reoccurs anywhere from 20 seconds up to a few minutes. I'm afraid my tire is going to fly off or my drive shaft is going to drop. There is no unusual noises or thuds if I go on and off the gas and the universal joints seem tight, and there is no vibrations from on steering wheel.
View 10 Replies1991 chevy silverado 1500 4.3 ... Cruising at 55 down highway truck died for 2-3 seconds only to refire itself. After doing so for a few days it wouldn't start at all. Changed fuel pump,fuel filter and all spark plugs. Now runs fine until I shut it off briefly. Then it stalls on me on 3rd,4th and 5th gears. Bucks badly. Is it a fuel issue or something to do with starting it while it's warm. Also it runs good with the check light ON. Soon as it goes off it starts shutting off and refiring itself when I give it gas.
View 1 RepliesI got a 2000 f250, 5.4l, I got a check engine light bout 2 weeks ago and didn't experience any driving issues. The code was p0171, just recently I've been experience troubles idling, if I let my truck idle for about 3 minutes it will want to shut off, also on acceleration the hole truck bumps, feels like I'm in an earthquake. Where I should start with this problem?
View 11 RepliesSeveral years ago I had to replace the fuel pump - truck had about 100,000 miles. Within the last 4 - 5 months I have replaced the fuel pump twice and just today (about two months since the last replacement), the fuel pump has failed again. That has been the pattern now for the last several months. I have had the work done by one of the reputable car repair shops in town - they have also done work on my 2004 Impala with no issues with the repair. There must be something else going on besides just the fuel pump going bad. What would cause so many fuel pump failures.
View 16 RepliesI have a 1998 Chevy K1500 4x4 which is experiencing issues on two fronts: brakes and general operation.
For the brakes, over the last couple years, we have replaced just about every part of the system, including - master cylinder - calipers - brake lines. In addition, in the last week, I worked with a local mechanic to bleed the lines and he turned the rotors as well. The result is that while the truck does stop, the pedal height is still really high and feels like there's no pressure until the pedal's nearly to the floor. I get the feeling that if I needed to stop abruptly or at a higher speed than 35mph, I wouldn't be able to. I'm not sure what needs to happen next.
As to the general operation: the first time I start the truck on any given day, it fires up and runs smoothly. If I take it across town, however, and put it in the park, it gasps, sputters, and dies. It is then very difficult to get the vehicle to start again--usually, I have to push the gas pedal all the way to the floor and grind the starter until the engine turns over. After that, I have to keep my foot on the accelerator for 15-30 seconds at around 3000 RPM as the truck shudders and lurches, until it smooths out. Once I put it into drive or reverse, however, it dies, unless I am quick to push the accelerator again. Until recently, the truck had only been driven four times in the last two years or so. So far, I have: - replaced the air filter - added fresh gas (to the old) - added an engine treatment (Sea-Foam) Everything I have done is stuff that needs to be taken care of anyway, and I want to take care of all the little things before I take it to a dealership to have a full diagnostic run on it. I also plan to have an oil change done on it this week.
Do I have to pull out the complete switch assembly, or could it be some thing else?
View 4 Replies2005 Dodge Ram 1500 SLT Big Horn, 5.8L V8 Hemi my air conditioning only works when I'm driving forward, and does not work at all any more when I'm sitting still at an idle. this is a new problem. the A/C has worked like a champ for the past year (since I started using this vehicle). I even refilled it by myself last summer, with no issues until now. when it is at idle, I hear a clicking coming from the A/C system, and the RPM's arch a little bit. then it clicks again, and the RPM's go back down. it does this 2-3 times a minute. also when at idle, the air is VERY HOT, considerably warmer than the outside air. also, I have a pressure gauge for the A/C system (came with the refill kit last summer) and it says that the system is holding too much pressure. it suggests a possible mechanical problem.
View 8 RepliesMy car stared to make this horrible screaming noise like a bad belt when I was on the freeway. When I would accelerate the slightest it would go away. Take my foot off of the accelerator, the noise would start again. I pulled over then the check engine light came on. I had it towed home.
View 9 RepliesThis make and model is the same as a Chevy Trailblazer. It has 124K miles on it, when it's cruising, there is no weird noise from the engine, but when I give it gas at any speed, there is a distinct sound coming from the rear of the engine. It sounds like when you put a playing card on your bike and the spokes hit it, but faster. The more gas, the louder the sound. It's gotten progressively worse lately. My first thought was rattling valves, but I'm not sure. It also sounds like a hole in a vacuum hose or something. With the hood up and an ear to the engine, the sound is definitely coming from the engine, not around it, and toward the rear.
View 2 RepliesI recently bought a 2004 Hyundai Sonata 4cyl with about 65k miles. In the past few months I've noticed that it likes to sputter and hesitate at times, mostly in lower gears when I'm not accelerating hard. At highway speeds it's mostly fine. It's also fairly random - some days it's really bad and others it's fine. Also seems worse when in reverse. I don't think the plugs have been changed so that's one idea, but I'm wondering if it's a bad fuel filter, exhaust manifold leak or something else. It's not throwing any codes (and yes the light works) and it has never stalled completely out.
