Chevrolet - Corvette :: 1986 - Vibration And Shaking At 65 - 75 Mph
Jun 19, 2011
I have 1986 Gold Corvette, which now has Antique Virginia Plates. I had a terrible Vibration at 65 - 75 MPH that would shake the car so bad I could not drive it more than 20 minutes and I could not tell if it was in the front or the back.
I had the following installed: Front and Rear Wheel Bearing/Hub Assembly (Timken), Front and Rear Brake Rotors, Front and Rear Rebuilt Calipers, Front and Rear Hawk/ Wellman HPS Brake Pads and four Stainless Steel Brake Hoses.
Now the vibration is about half-gone, but still shakes the GoldVette at 65 - 75 MPH, and I still cannot tell if it is in the front or the back.
A few years ago, I replaced the Rack-in-pinion and Tie Rod Ends. What do I replace next to eliminate the vibration so that I can drive it about 100 miles?

I am having a couple issues with my 94 Corvette with Auto Transmission with 107k miles.. First, when I am coming to a stop, from like 2 mph to full stop, I am getting like a clunking that sounds and feels like it is coming from behind me and to the right (from rear middle of the car). It does Not do this if I shift into neutral b4 I get to low speeds.
The second problem is, I got caught in a very heavy rain last weekend, and the digital speedometer area started blinking off and on about once or twice per second, and the "idiot light" panel lit up like a Christmas tree. The car started sputtering but never stalled out...it was almost if it was turning itself off and on repeatedly. I pulled over under a canopy, and waited out the brief but intense downpour, and its been fine ever since (about 100 miles), but it has only been driven in nice weather since. I checked the battery connections (and that's about it) and they were tight and clean.

My 2003 Corvette has 17,000 gentle miles on it. At around 15,000 miles I found that I couldn't get the car into 5th gear. It has a grinding metallic sound. All the other gears and the clutch work fine - and I've been forced to shift from 4th to 6th.

I own a sweet 2008 Corvette with 31,000 miles. I have only use Mobil 1 synthetic oil. Every spring, after the winter hibernation, I change the oil despite having only 5,000 to 6,000 miles between oil changes. My question is, should I continue to change the oil once a year or can I wait to change it at the 10,000 mile interval.

My car runs great except occasionally after I drive awhile, park and than restart to continue, it starts right up but stalls out 20-30 seconds later. I turns over but will not run. I have to let it sit for 30-45 minutes and than it starts up like a champ. I suspect fuel pump but would like an expert opinion. Garage says they can find nothing wrong and to bring it in when it happens... how do I do that.

Been fighting a starting problem for months with a 1976 Corvette. Car starts fine on first try, but if I shut off the engine, it won't crank again for hours, usually overnight. All I get is a buzzer noise when I turn the key - no starting motor noises. This happens no matter how long the engine has run, be it 30 seconds or an hour, so I don't thing the starting motor is getting hot. Car has a new battery and alternator - that didn't solve anything. What to check or replace next? Starting motor? Solinoid? Ignition switch? By the way, the car has a manual transmission.

1994 corvette auto trans, when car is parked or in drive with foot on the brake will start to idle up, the back down and like lunge forward if in drive and foot on the brake. Then if you drive it, and step on it, it will miss fire. My mechanis put it on his scanner but it showed no problems. The opti- spark, wires, plugs were replaced 2 years ago and 12,000 miles ago.

I have a '95 'vette LT1 that I bought new for my 50th birthday. I only drive it about 4-500 (yes - hundred) miles a year and for the most part it sits in the garage, gets washed and waxed, and put away. 51000 original miles, the first 40000 put on in the first 1 1/2 years. I've had an ignition and fuel injection problem since I bought it. Get's fixed then some new ignition/injection problem comes back. Here's what it does now: car starts fine, runs about 30 seconds with no problem, then starts to miss, runs very rough and very rich (can smell it in the exhaust). After about 3 minutes, the engine smooths out and 2 seconds later, the "check engine" light comes on and the cooling fan starts to run. It runs fine for about 5 minutes, then "check engine" light goes out, fan stops, starts to run rough, misses, gas mileage (per the dash display) goes to about 5 mpg, runs rich, etc. Then the cycle starts again with the "check engine" light and fan coming on and the car running fine. I have no clue.

I placed my Corvette with a consignment seller this summer. When he had no action, I took the car back but...battery dead. Fully recharged it, car started immediately (first time in 2-months) but then died and will not restart. My ace mechanic has replaced fuel pump, distributer, but no fire. Indication is weak/no signal at he injectors. Could this be residual Theft Prevention system? I had that fail years ago and I pulled the module and the car has done fine for 4-years, until now.

My 40 Ford pickup is on an 86 Ranger chassis and uses the stock Ranger steering gear. My question is about the connections on the steering box. I'm using a GM power steering pump and several steering gear vendors have told me that outside of needing to adjust the pressure for the correct feel, the combo works. I fired the truck for the first time tonight but the steering wheel went crazy, shaking around and finally spinning on it's own to a hard left.
Some quick research leads me to believe that I have the lines reversed but it would be great to know for sure. I did manage to find on e diagram of a Ford PS box on Google and it shows the lines reversed of what I have set up on my truck and I can't for the life of me remember how I figured out what the plumbing should be when I installed it. Which port on the box is the inlet and which is the return?

I recently purchased for my son a 1986 camaro 2.8 MFI v6 the car had been sitting for over a year in the previous owner's back yard because it would not start.I have had a mechanic do the following: heads redone, replace the distributor, replace the timing chain and gears, new wires, and emptied the fuel tank and replaced the fuel filter.
I picked up the car and it ran for about two week no problem. Then it started diying occasionally when you let of the gas to come to a stop, so he replaced the fuel relay switch thinking that it may be going bad. The next day he had been driving it about 15 miles when it just died and would not restart. We shot a little starting fluid to see if we could get it to start and get it back home. it fired up and ran all the way home and died when turning into the driveway. and would not start again.
We replace the fuel regulator the car started right up and he took it for a test drive. The car ran about 4 miles, long enough to warm up and died again and would start. and again we were about to get it started with starting fluid to get it back home. pulled in the driveway and it dies. again it would not start, let it sit all night and the next morning still would not start finally got it to start with a squirt of starting fluid and moved it into the garage. shut if off and then tried to start it and it worked 5 times in a row.

A friend of mine has an 86 Chevy 1/2 ton, all origional. His problem is that the truck is "slow" going into reverse, but once there, feels "solid". I haven't personally looked at the truck, and am not sure what his concept of "slow" is. I understand there's probably not enough information to determine the cause, but it doesn't hurt to try.

When I remove my foot from the accelerator, my '86 Land Cruiser makes a noticeable and resonating vibration. It generally occurs at deceleration from about 60-65mph or when I'm going down a hill, when I habitually feather the accelerator to regulate my speed regardless of the slope, and rattles the whole truck to the extent I can feel it through the back of the driver's seat. The truck has always had a certain looseness or slop in the driveline; if I'm not careful to feather the clutch release, the truck starts off in a herky-jerky motion. Yesterday, I was nosing around under the truck attempting to discover the source of the vibration. When I grasped the rear drive shaft (it has a second drive shaft for the front wheels), there is noticeable free-play of about 5-10 degrees in the shaft rotation. Is this normal for this truck?

Lately the voltage gauge sometimes starts to wander upwards toward the 18v red zone. When it does it wanders up and down a lot, but mostly well above the center 13v. Sometimes I left of the throttle a little and it goes back and stays at normal, and sometimes it doesn't and bounces up again as soon as I press the throttle. Doesn't happen on every drive, just sometimes.
I thought it unlikely this was a bad voltage regulator, since it's a pretty new alternator, 2 years tops. So I thought I'd see what other possible causes could be. (Why do they make the voltage regulator internal to the alternator now anyways, since they seem to go bad more often than the core? Can I just add an external regulator like the older trucks had?)
I've heard over-voltage can ironically sometimes be caused by a short, since the regulator dumps more voltage into the field coils because the main coils are showing they aren't delivering enough current (because it's all being soaked up by the short), resulting in an overall over voltage as the alternator tries to compensate for the voltage drop of the short.
How do I tell if this is the cause of the overvoltage or if it's something else instead? If it is a short, where could it be? I'm assuming it must be somewhere weird, because almost any normal place I could think of for a short would simply blow a fuse. Or is there such a thing as a partial short-- high enough resistance to not blow a fuse, but low enough to drive the alternator nuts?
Could it be related to overheating? I initially thought that was a possibility, because it began around the time the weather turned warm here, but on any given day it seems pretty random and not tied strongly to excessive speed or going up hills.

I have a 1986 Chevrolet El Camino with a small V-8 engine. The vehicle has 150,000 miles on it. It starts and runs fine. It does not use oil. My problem is the oil pressure. After the car runs for a short time, the oil pressure starts dropping. It will drop all the way to 0 if I let it. I have had the sending unit replaced and it did not work.
I have had two mechanics look at it and they have not been able to solve the problem. One checked it with a mechanical gauge and confirmed the low pressure. He suggested a higher weight oil and an additive. The other mechanic's solution was to raise the idle speed. I have had this vehicle since it was new and always kept the oil changed and all other maintenance done. I would like to keep the vehicle and complete any repairs necessary.
My question: Is the engine repairable economically or does the engine need to be replaced and what is causing this problem.

I have a 86 K5 Blazer. Six years ago put a new gm 350 a rebuilt trans. and had all the work performed for inspection. Truck was run once or twice over the years. This winter I got it on the road to push snow. I ran the blazer once for about 12 hours pushing snow, on the way home I thought I had a problem with the trans. Took the k5 out today 2/20 to pick up my kid at a neighbors house. Started out fine but at the large steep hill my k5 lost power. I pulled over to check the blazer over. It was idling fine but when I would rev the engine it was muffled. I drove up the rest of the hill (barely)and picked up my kid. On the way back I was quickly throttling the gas pedal which seemed to give little bursts of power. I am thinking that I have an airflow problem.

We have an 86 Chevy Silverado C10, all of the lights work on the truck except the headlights. We have replaced the switch, it has new head lamps. We hear that there is no fuse for these lights, that there is a circuit breaker but how to locate it or if it is really the issue. How to get the lights back on?
