Silverado :: 1992 Chevy 1500 Runs And Starts Great But Won't Do High RPMs
I have a 92 chevy pick up 5.7 with 159,000 miles. The truck runs and starts great but shortly after I bought it 3 years ago it developed a sort of misfire at higher rpm's, it's fine if I drive it normally but if I try to pass someone it will downshift then fall on it's face, (spit,sputter and slow down). some times I can feather the accelerator and it will come back again. I normally don't drive the truck in the winter but this week I was forced to use it and the cold weather is seriously affecting it, it took forever to get it up to 70 mph after getting on the highway. once up to speed it will do 75 all day without an issue.
I've replaced the plugs, wires, pulled the throttle body and cleaned it as the port for the pcv valve was plugged solid with carbon. I have not replaced the cap and rotor as they seemed to look fine. I have not checked the fuel pressure because it will break the tires loose upon take off and I don't think that would be possible if the pressure was low, would it?
Silverado :: 98 5.7 Chevy Truck Not Starting
I have a 98 chevy truck that won't start. After it sits. It was starting after cycling the key a few times. But now it won't start. Could it be the pump? I hear it running.
Or could it be the regulator? It was running good after it started. No check engine light, no gas smell, and no rough idle.
Silverado :: 98 Chevy Truck With 4L60E Has No Second Gear - Shift From 1st Into 3rd
I have a 98 Chevy truck with a 4L60E. It has no second gear. I was sitting in park for about 10 minutes with the engine running, then put it in drive and it never shifted into second. It felt like it went straight to 3rd. I played with it manually until I figured out I had reverse, 1st, 3rd, 4th and torque converter lockup, just no second gear. My acceleration rate was medium and when I reach about 27-28 mph it would shift from 1st into 3rd. It has 230K on it so I rebuilt it with all the typical parts - frictions, steels, band, sun shell etc., still no second. I then pulled the pan back off and replaced the spacer plate and put in a shift kit. While I had it down I put a corvette servo in and did an air check. It worked fine. I could feel the band tighten.
Both the 1-2 and 2-3 solenoids checked good at 23 ohms. I swapped their positions to see if it would make a difference. I also checked to make sure the 1-2 accumulator piston wasn't stuck in its bore, the spring was new from the shift kit. It was fine. Put it back together...still no second gear. When I originally pulled the pan off for the rebuild, the pan was free of any debris and was very clean. I then drove it a couple of miles to a local transmission shop. They put their scan tool on it and drove it around the block. There were no codes and the ECM was calling for second gear. It doesn't sound mechanical since almost all the parts have been replaced, rebuilt or inspected that affect the 1-2 shift. It sounds electrical. Is there anything I have missed?
Silverado :: 2000 Chevy Truck Won't Start - Security Light On
I have a 2000 Chevy silverado. I recently was having problems with the transmittion not switching correctly. Long story short the shop told me to fix the problem I had to put in
A new transmition as well as a new computer which I did, from another Chevy. It worked for a few days then The truck was not starting and had security light on. Had alarm specialist take look and he said the computer had to be reprogrammed. It was reprogrammed at merles. And was still not working. Its unable to start, starts at random once in a long while. ignition switch was changed and still gave same problem. Took to another shop they had a specialist take a look and he said the computer had to be reprogrammed again.
Also would it be possible to bypass the anti theft system by adding a remote start, or cutting some wires. I just really need to get this truck running.
Silverado :: 88 Chevy K1500 - Truck Lacks Power / It Idles Rough
I have an 88 chevy K-1500 4x4 5.7L ... My truck lacks serious power, it idles rough, sometimes wont idle at all, sometimes Truck Idles fine. I have adjusted the timing to tdc, and 4 deg. both ways still runs like crap.. Sometimes I can keep it idleing, put it in rev. or drive, and it will die. I have no power and if I put my foot in it too much it will backfire. but will only backfires when in gear and press on the gas to put a load on the motor. I have replaced the: tps, map, egr, pcv, distributor, cap, ignition coil, rotor, plugs, wires, timing chain, both sprockets cam and crank, checked all hoses for leaks, replaced the injectors, the O2 sensor and have changed the intake gaskets. And am still having no luck...... I am bout to just drop an M80 in the gas tank and watch her burn..

2006 chevy 4.3 v6 5 speed manual trans. Very hard to shift into and out of gear , the truck has about 80,000 miles on it , its had the new trans fluid gm replaced for smoother shifting. If you hold the clutch pedal down on the floor hard it works fine. It all most like the pedal it screwed up. The pedal ass is plastic junk, I am thinking the pedal is bended. The clutch does not slip and I tried bleeding the clutch master cylinder and there are no leaks anywhere !

Drove the truck one week ago today and it ran perfectly fine. Drove it last night for about 20 minutes - ran fine. Drove it again today just 1 minute up the road - ran fine. Started it again this evening and drove it 5 minutes down the road - ran fine. Stopped and put gas in it - now it's not fine. After putting gas in it it refused to start but will turn over. Put a booster pack on it and it will start but would only stay running with the gas pedal pushed all the way to the floor, as soon as you took it off it dies. Now it will not stay running even with the gas pushed all the way down.
View 5 RepliesGMC :: 1950 - Distributor Module Not Working?
I have a 1950 GMC truck that I restored with a 350 small block v8 with a stock set-up. I now have 30K on the motor and it runs great except for one problem: The module in the HEI distributor keeps failing. The mileage between failures is random: 3k, 5K, 8K. I have now put in 8! I pull the module out and test it: Yep, cooked. I have replaced the cap, coil, and alternator. I think the distributor is not grounded properly. There is no tach attached to it. What is the source of problem? Should I just replace the whole distributor and hope for the best?

I have a 92 k1500 with the 5.0 L in it. I suspect the distributor drive gear is worn, and even if its not it isn't going to hurt anything to replace it because its the original OEM drive gear and the engine has 233k miles on it. So what I'm looking for step by step process removal and re installation?
View 2 RepliesChevy - Suburban :: 2003 - Programming / Calibrating Quadra Steer Module?
I bought a 2003 2500 4x4 suburban a couple of weeks back. The seller had purchased and installed a new module for the quadra steer system before I bought it but hadn't had it programmed yet. Not sure what's involved in programming the module - something best left to a chevy dealer? From what I understand, quadra steer is relatively rare because GM had priced it out of sight, but those who have it love it so I want to get it working (seller told me he can do a U-turn on a two-lane road + a foot or so of shoulder on each side - pretty unreal for something that size).
View 3 RepliesSilverado :: Cruise Control On 2002 Chevy Not Working
The cruise control on my 2002 Chevy 1/2 ton Silverado doesn't work. Went to boneyard and bought a module but it didn't fix my issue. Borrowed a multimeter and tested the cruise control module plugin. The only pin that came up with a incorrect reading was the first brake test. It's suppose to have 12 volts with brake pedal up but showed about 30, so I changed the brake light switch. Still no cruise control.
Since I have a high reading on the brake pin, do you think I have a wire issue there or would my problem be in the multi switch wires by the steering wheel?
C/K :: Chevy Silverado Z71 - Water Sound Under Dash When Accelerate
On my 1999 Chevy Silverado Z71, a gurgling water sound is present everytime I accelerate. Are there any other Chevy owners that have had this same problem? If so, how was it resolved?
View 14 RepliesSilverado :: 1994 Chevy - AC Compressor Engages But No Cooling Really At All
The issue I'm having is the A/C. When I got the truck the A/C was completely freezing. Recently however, the compressor was having issues not engaging and I fixed that by simply plugging the cord to the accumulator thing. . Now the compressor engages, but is not cooling really at all. It is an old truck and the compressor is a little worn from what I see maybe 2mm space when not engaged. I checked the levels of freon/coolant with a gauge and the amount is perfectly fine. Plus there seems to be no leaks.
View 1 RepliesSilverado :: 1993 Chevy 2WD - When Accelerating RPMs Go Way Up And Won't Shift
I have a 1993 Chevy Silverado, 350, 2WD. It has a 4L60E transmission. I just started having a problem shifting from 1st to 2nd. When accelerating the RPM's go way up and won't shift until I let off the throttle. Then it shifts into all other gears normally.
If I accelerate slowly. it will shift into 2nd at about 16 MPH. It will then shift into all other gears normally. I have replaced the Throttle Position Sensor, flushed the transmission and replaced the filter and fluid. This made know change in performance.
I am now suspecting that it might be the 1-2 shift solenoid. The check engine light is not on and everything else works fine.
Silverado :: 1993 Chevy RWD Lost Power And Acceleration
I have a 1993 Chevy Silverado rwd automatic 350 5.7. It died on me on the way to work this morning. It slowly lost power and acceleration. The lights and radio all worked. When I tried to restart, it tried to start but then just cranked like it had no fuel or spark.
I had it towed home and checked the following things. I removed the fuel filter, it is clear. I verified that the fuel pump was working by turn the key to the on position while the filter was off. Good stream of fuel. I verified that there was fuel to the TBI. Good spray while cranking. I verified that there was spark by pulling a plug out, connecting to the wire and cranking the engine. Spark seemed weak but there was spark. The front plugs were dry, but the rear plugs, especially #8 was very wet. I verified the timing by pulling the #1 plug, removing the distributor cap and checked the rotor position. I bumped the engine to get the #1 piston to the top of the cylinder and the rotor was point directly at the #1 plug wire. The cap, rotor, plugs and wires are only 1 month old.
I also tried to check the ignition coil by disconnecting the coil wire from coil, and slid the boot back to expose the contact. I held it just of the coil while the engine was cranked, but did not actually see a spark at the coil. I did not hear any arcing. I pulled another plug and checked for spark. Again i had spark. Just seems weak to me. I am on my way to the auto parts store to get a new coil.
Chevy - Silverado :: 2008 2500HD Front End Clunking
I picked up a very clean 2008 Silverado 2500 HD. W/60K miles. The vehicle has been very well cared for as I know the orignal owner. I have zero complaints with the truck other than an annoying front end clunking. Its very reminiscent to the intermediate shaft issues of my 2003 2500HD.
Basically when hitting very small road imperfections, I can feel/hear a clunking in the front suspension. I can also duplicate the issue by rocking the truck left to right with the steering wheel while going 20-30MPH. I figured, stabilizer links. I put the truck up in the air, & can't find a thing wrong. Links are tight as well as the ball joints & tie rod ends. Were these trucks know for a common clunk like this.
Chevy - Silverado :: 1996 Won't Shift Into High Gear
My dad's 1996 Chevy Silverado will not shift into hi gear. The truck starts up fine and he can drive it but for some reason it won't shift into hi gear. Him and I are clueless as to why it won't. He has a 1996 Chevy Silverado, 6.5 liter V-8 automatic transmission, and its a diesel. We really want to fix the truck ourselves so we are trying to avoid taking it to a shop.

I have a 1999 Chevy Silverado 1500 extended cab. Two nights in less than a week, my horn has went off in alarm mode. Is there another reason for this other than an attempted jimmying of the lock?

View 1 RepliesChevy - Silverado :: 1999 - Shakes Badly At Several Speeds
I have a '99 Silverado 1500 with a 4.3L V-6 amd 188,000. It picked up a problem recently that's been stumping me. Occassionally, and for no reason I can sort out, it starts to shimmy badly. This behavior has come about at several speeds. Sometimes just cruising down the road at 35-45 it starts to shimmy and wobble and the steering wheel shakes as if a wheel is horribly out of balance. Other times this occurs at highway speeds - it's noticeable and alarming. The problem can last a long while; othertimes the symptoms disappear in a few seconds. The first time it happened I thought I had a flat or was about to lose a wheel - this is not a subtle problem.
I've checked several things and came up empty. No delamination in the tires and nothing out of round, but just to be sure I had the wheels balanced and rotated - the balance was spot on when checked. Alignment is good. Did those things, but the symptoms continued. The vehicle is high mileage so I put in on the lift and checked the front-end. The steering rack has a very slight amount of play and the hub bearings have a very small amount of play too - I'll get after those, but they're not causing this intermittent problem. Everything else is tight. Shocks are fine, brakes are fine, I checked the rear-end as well - everything is straight and true. Air pressure is set correctly. I checked the driveshaft for runout and play - that's not the problem. The truck has never been in an accident and nothing seems misaligned.
The truck drives like a new truck most of the time, then suddenly, on a smooth road, it starts wobbling around. I'm starting to believe the problem might lie under the hood. I had a problem some time back with misfiring and the truck bucking - this turned out to be a worn distributor. A new distributor, rotor and wiring solved that problem. But these symptoms are not similar - this is not a bucking problem; the entire vehicle starts to shimmy and wobble with the steering wheel vibrating back and forth. It's hard to tell, but I cannot detect any misfiring or rough running in the engine when these symptoms appear and I have no 'check engine' warnings.
Are there any engine/transmission/drivetrain related issues that could cause intermittent symptoms that feel like an out of balance condition? A few other facts:- I have noticed the truck is a little down on power lately- The fuel economy has dropped off - I used to do around 20, now I'm down to 16mph highway- (Very) slightly rough idle
