Chevrolet - 3500 :: 1993 - Truck Starts Surging / Tachometer Jumping From 2000 To 2500 RPMs
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....
1995 Chevy 1500 With 5.7 Engine - Truck Completely Stalls Out And Has No Power
I own a 95 chevy 1500 with a 5.7 engine. The other day I'm driving home and my truck completely stalls out and has no power what so ever. To be more specific I didn't have lights, radio, key buzz nothing. Well by the time I got the under the hood I had power again and it cranked right up. I put it in drive and 5 minutes down the road and it stalls again with no power what so ever. I've been having problems recently with it stalling at stop signs/red lights but never with a loss of electrical systems. What this could be?

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.

My wife drives a 1995 Chevy Astro. It has twice now stopped running with no warning. This happened while driving down the road. The headlights and engine cut out, but the turn signals, power windows, radio display, and such have power. Once it sits for a couple of hours, it starts right up and runs fine for weeks.
Is there an electrical connection of some kind between the fuel pump and the headlights? What might be going wrong?
Chevrolet - 1500 :: 1995 Truck Cuts Out At Idle
My 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."

I have just swapped a new Vortec V-8 engine into my 1999 Chevrolet Suburban K1500 4*4, now when I start the truck and put it into reverse (foot still on brake pedal), I let off of the brake and the next time I step on the brake pedal the truck stalls. What would be causing this? I have no error codes on the computer, my fuel pressure is good, I just replaced the fuel pump. I think that it might be a sensor somewhere, but I am not sure where to look.
View 2 RepliesToyota - Corolla :: 1995 - Misfire Around 3000 - 3500 RPM Only When Warm
Car: 1995 Corolla 1.8L automatic
Symptom: misfires around 3000-3500 RPM only when warm.
I have replaced the following:
-Spark plugs, wires, cap, and rotor
-Ignition coil
-Fuel filter
-Poured some quality fuel system cleaner into the gas tank
The car stutters when accelerating in any gear hard enough to reach the engine speed that the misfire occurs at. It doesn't backfire, it just misses... I am confused since so many of the misfire issues I know about that are RPM specific are spark-related.
I have considered cleaning the injectors, but don't want to go through the hassle to remove and have them cleaned unless I really have to. Checking if hunch on the injectors is correct? Something else?
Chevrolet - 3500 :: 1996 - Won't Start Sometimes
I wait for the glow plug to stop before attempting to start. Then it's like Aaron Tippin sings, "sometimes she runs, sometimes she don't". It turns over fine. When it's running, it runs good. But most times it won't start. The fuel is being stopped somewhere. The in tank pump is working..I can hear it when I turn on the key. What else can I check?

I suspect there are very stinky mushrooms growing in the debris inside the ventilation system. We live in Florida and the van sits outside in an area in our yard where stinky mushrooms grow at certain times of the year. I have tried spraying Lysol in the outside vent with the fan on full. That seems to have worked over time but can I dump some vinegar in there without harming anything?

I have a '89 Chevy 350 v8 in my boat. It starts fine, but then stalled when decelerating, and would not start. I smelled some gas fumes when trying to start it after it had died. It started up fine the next day without problems. The distributor was just replaced so I know that is good. Not sure if this is related, but occasionally it will diesel a couple cycles when I turn it off. Could this be the carburetor, or something else?

My 2006 Chevy Express 3500 (cutaway) 6.0L won't start when the outside temperature is below 35 degrees. Warmer than 35, it starts right up. Seems to be a fuel problem, as it fires, but doesn't keep running. I can start it by fooling around with the position of the gas pedal, but usually it takes a few minutes of cranking. My mechanic thought it was low fuel pressure and replaced the fuel pump- a thousand dollars later, it is no different.

Have had the vehicle since 24k miles - currently at 43k and just started doing this in the past 5k miles. When cruise control is engaged, and we go over a bump (of decent size) the cruise disengages. Perhaps a bad connection with a sensor? I do not know the cruise system that well on this vehicle and would like to know where I should start looking.
View 1 RepliesChevrolet - 3500 :: 1994 - Intermittently Dies At Idle
94 Chevy W-4 wheel-lift wrecker 5.7L TBI4l80e trans
Had a run of about 100 miles round trip on Wednesday. On the way back running at 65 mph on the interstate, got a couple of quick muffler-end back fires and engine died. Coasted to shoulder. Had memory of almost exact same incident last year and it was dead ignition module. Fortunately had a spare (used) module in glovebox. Swapped it out and engine started right up. Remainder of trip didn't quit, but ran very rough, lots of stumbling and getting it up to 60 mph was a struggle. Also when I got on surface roads it died twice when I was sitting stationary. It would restart, BUT only after cycling key; if I just turned to the key to "start" from "on" it would crank but not fire.
Limped it to my tow buddy's shop where I freeload and told him the tale. He said, "throw those old spare modules away and get a new one". Called the local parts house and had them send two, one for installation and one for glovebox. Took for test drive and appeared to be running okay except idle was a bit low. Couple of hours later went on a call and first stop sign I came to, went "blip" and I'm dead in the water again. Same story as earlier, must turn key off and back on to get it to fire. Drove rest of day without incident. Yesterday, no issues all day, drove total of about 120 miles both highway speed and surface. Gassed up this morning and mpg was above average (yay!), actually about .5 above average which is significant improvement (about 6%). Success?
Today died four times while sitting still. Same having to cycle key for it to fire. Did some quicky t/s to satisfy my curiosity about the key cycle thing. With truck running, pulled fuel pump fuse to kill truck. Then reinserted and it started up without having to turn key to off. Tried same thing by pulling one of the module plugs to simulate loss of signal to ignition. Reconnected and again fired up without key cycling.
No codes at any time since this came up.
Swapped out the module since I had bought a spare, no change.
Ohmd the ignition coil and no problems noted. So far, only dies sitting still at idle.
Additional info:
Plug wires, cap, and rotor <1000 miles. Distributor low miles and negligible play in shaft. Pickup coil checks right in middle of ohm range. None of these, of course, should need to have the ignition key cycled to restart if they caused a stall.
Next up will be replacing ignition relay (had to order), but I'm not very optimistic.
Chevrolet - 3500 :: Slow Coolant Leak Above Rear Transaxle
I have a small leak of greenish fluid (appears to be coolant) coming from a silver/aluminum tube that runs the length of my van, just above the left rear transaxle. The leak seems to be in the tube, near a support that keeps the tubing flush against the undercarriage. It is a slow leak, but it is dripping onto the transaxle/transfer case, and is beginning to leave a small puddle on my driveway -- gets a little worse each time I drive. I haven't noticed much loss of coolant in the reservoir, so not sure what this is and how to fix it. I have a photo. I am thinking the tubing might be part of the heating system.
