Chevrolet - 1500 :: Truck Makes Toot Noise From In Front Of Driver Under The Hood While Accelerating
Six 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.
Chevrolet - 1500 :: Hesitation In Truck When Accelerating
1992 WT pick up 263,000 miles had new head gasket installed valves lapped and tune up it was doing it before and does get better when truck warms up, but still can hesitate at times. 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.

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?
View 1 RepliesChevrolet - 1500 :: 1990 - Running Rough / Hesitating / Lurching And Not Accelerating Smoothly
My 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.

View 8 RepliesChevrolet - 1500 :: Grinding Noise When Attempting To Go From 2H To 4H
Year: 1999Make: Chevrolet
Model: Silverado 1500 LS
Issue: Bad Transfer Case
Late model 99 Chevrolet Sliverado 4x4 with push button transfer case. At the end of last winter the transfer case began a grinding-noise when attempting to go from 2H to 4H.
I have a great mechanic who has proven both his skill and honesty to me a few times now. I took the truck in for diagnosis. His hope was that the electronic transfer may be faulty but unfortunately found metal shavings when he went to check the lubricant in the transfer case.
Diagnosis: Bad Transfer Case - Replacement necessary.
Mechanic has recommended a salvaged transfer case from reputable salvage dealer.
I have sourced a rebuilt transfer case with manufacturer warranties from a "major parts chain" for approximately 1/3 more cost.
My debate: The truck (while very late model), has a rebuilt engine that has less than 50k miles on the rebuild. I have expectations that I will continue to drive and maintain this truck for a very long time.
Although I am always aligned with less cost, my first response is that the rebuild from "major parts chain" is warrantied and far less likely to require a replacement in the remaining life of the vehicle.
However I am also uncertain how to evaluate the existing transmission. Presumably it has >100k. Is there a risk in pairing an OEM rebuilt transfer case with a transmission this old?
Chevrolet - 1500 :: Growling Noise Only Happens When Accelerate
My 1999 silverado growls in when it's in 4-Hi. It seems like it only happens when I accelerate. And it's only in 4WD, not 2WD. So I'm worried about the front differential, especially since I just got a bunch of seals replaced and read that problems with the front diff can make them go bad. Did the shop just ignore a likely problem? I just bought the thing last summer, so I'm not sure if the sound changed much over time. I do need front shocks, that doesn't seem related, does it?

Chevrolet - 1500 :: Won't Start Up - Cranking Noise - Dies Randomly
Truck has 190,000 miles. First, every now and then the truck won't start. Turn the ignition key to the start position and nothing happens - like the battery is dead. Turn the key back to the off position, wait maybe 10 - 15 sec. Try and start again - starts right up. This maybe happens about half the time I start the truck. Always seems to start first start attempt of the day. Only later does it start to behave this way.
I took it into a repair shop and they claimed it was the starter relay. After the repair (about two weeks) it seemed fixed - started all the time. Then a couple of days ago it began to do the same thing again. Only now, maybe 10 - 20% of the time doesn't want to crank (vice 50% or more before the repair). Doesn't seem to be the battery because when it cranks it cranks very strong and starts right up.
Now additionally, today, the truck just dies while driving. Doesn't stall or run rough just before dying - just dies - like turning the ignition switch to off. Interestingly, it starts right back up after this - no extended cranking, etc., just starts right up. I have tried "jiggling" the start switch to see if maybe it is failing, but it has no effect. That is, when the truck won't crank, "jiggling" the switch won't make it crank, and "jiggling" the switch while the truck is running doesn't cause it to die. Sometimes, the waiting 10 -15 secs or so between crank attempts doesn't work - that is, it doesn't crank, but if I open up the hood and take the starter relay out of its socket and put it back in, it cranks.
Chevrolet - 1500 :: 1995 - Low Spinning Noise Coming From Area Around Starter
I have a 1995 4X4 Chevy Silverado. Well tonight the lower radiator hose came off, and all the coolant drained out while my wife was driving it around town. She noticed that the temp gauge spiked, and tried to get home. The truck stalled, was able to restart it for a moment, stalled again and now when we try to start it up there is a low spinning noise coming from the area around the starter. I think it might be the starter trying to engage the flywheel. My question is whether or not this could because the motor has seized, or is there another symptom that could potentially make this noise.

View 8 RepliesChevrolet - 1500 :: Loud Whining / Spinning Noise On Startup - High Idle
My question is what could cause a high idle?I have a 95 Chevy pickup 4x4 with a 5.7... Recently the lower radiator hose fell came off the radiator, dumping the liquids all over the street. The motor shut down, and every time we went to start it there would be a loud whining/spinning noise. We thought that the motor seized, so we pulled the plugs, turned the motor by the crank bolt.Turned out that the starter went bad, the spindle and bendex werent catching on the flywheel.
After examining the flywheel teeth, and gapping the plugs to the recommended manufacture gap, (they werent when we pulled them), we got a new starter installed. It started right up! But it ran at a high idle, around 1500-2000 RPM. I did not have a chance to really let it warm up (it was cold and raining). Now there is a gray flexhose that is running from the air filter housing down to the exhaust manifold. If i remember correctly, it was not seated very well when I took it off. Could it be causing too much of a vacuum?

View 1 RepliesDodge - Ram - 1500 :: 1997 - Idle Roughly At Warm / Accelerating
I have a 1997 dodge ram 1500 4x4 with the 318ci engine. 140,000 miles. Fall 2009 I replaced the CAT (old one had broken loose and was rattling around inside) and both o2 sensors. A few months later, when I'd start the truck cold it would idle fine then as it warmed at idle it would run rough almost quit then idle up and run fine all by itself. When started warm it would idle fine then hesitate while acclerating a few times then run fine. No check engine light. Now, about 10 months later check engine light is on (P0138 o2 circuit high voltage bank 1 sensor 2). I have put about 5,000 miles on the new CAT. I checked the wires and connections for damage and found none. Also, new cap,rotor,plugs and wires.
View 3 RepliesToyota - Rav4 :: 1997 - Hesitates Between 1500 - 2100 Rpm While Accelerating
I recently purchased a 1997 Rav4 (3F-SE Engine) with 162000 miles. Overall, it is a great car. The only problem (besides a clutch, which can wait) is that it hesitates/bucks between 1500-2100 rpm while accelerating. This happens usually on a shift change from 1st to 2nd, or while in 2nd and after decelerating to make a turn. This only happens after the engine has warmed up, i.e. the temp gauge is above 25%. When cold, there is no hesitation at all. It just passed emissions testing. Check engine light is off. I recently replaced the TPS (and adjusted it properly), with no change in symptoms. This car does not have a MAF sensor.
