I installed a new motor in a 1990 chevy Silverado about 5 months ago. every time i start it there is a loud clunky noise which goes away after about 1 or 2 minutes.I took apart the exhaust.. why does #2 cylinder have rust on the exhaust port not black soot?
View 1 RepliesI 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.
I am trying to get some advice on a diagnosis for a transmission problem i'm experiencing with my vehicle? It's a manual transmission and the sound i am hearing is when i shift gears is a loud whirling grinding sound. It's really loud in 2nd 3rd and 5th and doesn't stop.
View 1 RepliesI have a 1997 Chevrolet pickup, the No.5 Spark Plug Builds up and fires to one side, I can drive up to 50 miles per hr and it misses once in a while, I can get up to 60-65 and it does the same. I changed out no.5 Fuel injector and it still misses, I changed out the seals on no 5 valve, I changed out the fuel filter; and the CSFI makes a whistling noise & the sequential fuel box makes a vibration. I can put the old filter back on and it doesn't whistle or vibrate. I put the new filter back on it whistles and vibrates the sequential fuel box. The trouble light does not come on and tells me to check the engine. Do I need to replace the fuel pump?
View 3 RepliesI was at the bank today and when I put it in reverse to back out, the car jolted and then it rolled forward slightly while at the same time sounding like there was grinding. I immediately put it back into park and the noise stopped. Then I tried to reverse again and it started making a clicking and whining noise and wouldn't back up. It sounded like it went into gear but it won't move. I was able to get it pushed out and the drive still worked. So I was going down the road and got up to speed and the shifting was significantly delayed.
It's an automatic by the way. So I tried to take it on the highway and it won't shift out of 2nd gear or 3rd. I know for a fact that overdrive isn't working so i'm doing 50mph down the road and hitting 2500 RPM. I don't know what the deal is but for about 8 months there has been a rumbling vibration when it tries to go into overdrive and when I accelerate quickly I force it to downshift and the rumbling goes away but it still shifted into overdrive when it got passed the rumbling and vibration. It's a 1997 C1500 2WD 5.7L Silverado.
1987 Acura Integra Automatic, 160k I have been noticing - mostly for every start (there are a few in between that did not have that sound).
When starting, a loud sound (some what unbearable) heard and was hesitant and then the engine starts. Once started it runs fine. It is not the usual sound that the ignition makes when going bad.
What seems to be the issue? Right after I drained and filled AT fluid, it heard the first time. I have been doing AT fluid since nearly 10yrs ago with Honda fluid. I only did drain and fill and it went smoothly. In 2007, the tranny was replaced. After starting, the car runs smoothly - it is only when starting or just before engine try to start. Batt and alternator tests fine.
It hardly did it today - I might have once heard a girding sound just before starting.
I have a 1990 Toyota 4-Runner, manual 5-speed transmission. About a week ago, while shifting gears, I heard a loud "popping" noise from the general vicinity of the clutch. I did not feel anything different in the clutch, it returned to the appropriate position and didn't feel any more or less "loose." However, after the "pop" it seemed difficult to get the vehicle into first gear and second gear, and I really had to "push" it to get it into gear, but it would not grind or anything else. Also, when shifting into reverse, it would grind loudly and be very difficult to get into reverse gear. If I turn the vehicle off, put it in reverse and then start the car, it works fine, though it seems like it "sticks" longer in reverse and takes a bit more muscle to get it out of reverse and into first again.
Additionally, when the shifter is in first gear, but the clutch is pressed, it seems as if the clutch is not disengaging entirely, because the car wants to move forward slightly when I take my foot off the brake, almost as if I'm letting my foot off the clutch a bit with it in gear. All of this has been happening pretty regularly, but the car has still been driving fine. However, today, the poor thing wouldn't start. This vehicle (like many manual transmissions) needs to have the clutch pedal pressed in order to start the vehicle. Even when I press the clutch all the way to the floor, the car won't start (and I know it is not a starter/battery issue). Given the other problems with the clutch and shifting gears, it almost feels as if the clutch was not getting disengaged all the way even when the pedal was pressed to the floor, and now that it won't start, I'm wondering what is going on. Does this model have a linkage adjuster that needs fixing? Is it something wrong with the clutch fluid? Or do I need a new clutch entirely?
So I changed my plugs and wires on my truck a few days ago and now every time I turn my key on a loud electrical noise comes from the engine. I thought it was the front right plug so I changed it. That went great for one day, then the same problem reoccurred. Done this many times never encountered such a problem. It will run obviously weaker than previously. 2000 Chevy Silverado5.3l vortec 4x4136,000 miles....
View 4 RepliesHere' the low down. I have a 90 4runner v6 4wd. It is intermittently making a loud rubbing noise in the front right of the truck. It starts randomly and sometimes stops on its own or will start when I hit a bump,it will stop when shifted into 4wd, or when I brake or turn hard to the right. but happens only a portion of the time. took it to mech, he removed front drive shaft and said prob went away, it seemed the vacuum pump or the solenoid that activates shifting out of 4wd is defective. So he manually switched off the 4wd replaced the front shaft and all good! but on my way home the noise began again. super frustrated, 3rd mechanic in a week.
View 1 RepliesSo about 3 weeks ago, I was driving down the road at about 55 mph, on cruise control, when my car just started slowing down. I looked to see all of my dashboards lights on and I realized my car was not running. I shifted into neutral and the car started right up again, but when I pushed on the gas it just kind of stuttered and shuttered before dying again. When I came to a stop, again the car started right up, but repeated the shuttering and hesitating when I pushed on the gas and tried to get going again.
So, I repeated, but this time i just pushed very gently on the gas, getting up to between 5-10 mph before the car died again. At this point, it just stopped running completely. The engine would turn over, but would not keep running. When I got it into the shop, the mechanic said they put a fuel pressure gauge on there and the readings indicated that there was plenty of pressure, no problems the fuel pump or lines.
After further research, the mechanic said he thought it was an electrical problem, that it could be the crankshaft sensor or the ignition switch module, but he just did not really know for sure. I had him replace the crankshaft sensor, since it was the cheaper part, and it didn't fix the problem. So now I am just kind of stuck on what to do here.
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?
I have a 92 chevy truck with a 350 engine that came out of a 93 chevy my problem is my module in the distributor keeps going bad when i spoke with the previous owner of the motor he told me that he had the same problem and advised me to change the distributor. So I took my distributor out of the original motor and put in but the problem still exist, also I have noticed that I have nearly twice the exhaust coming from the drivers side tail pipe as I do the passengers side.
View 1 RepliesOn 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 RepliesThe 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 RepliesI 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.
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?
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.
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.
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.
View 2 RepliesI 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? I live in a decent neighborhood with lots of pole lighting. Someone told me the keyfob battery was dying but I don't have the fob.
View 1 RepliesI 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
