Chevrolet :: 1986 Stall Out After Putting Into Gear / Intermittent Click Sound
I got a 1986 chevy g20 conversion van and I am having a problem with it once in a while it will stall out after putting it into gear it does not do this a lot but it does happen also smells like its running rich and until it warms up while the van is in park you can hear a intermittent click sound goes click click............................click...click no real rhythm just kinda does it then stops when in any gear besides park friend said it could be a small backfire. The engine is a 350 V8 4 barrel carbed.
View 1 RepliesChevrolet - Suburban :: Intermittent Surge Or Shudder Between 40 - 60 Mph During Acceleration
I have a 99 Suburban with very high miles. Going on 306K mostly highway miles. This is our baby and the best vehicle I've ever owned. This is a solid vehicle that I think we can get more miles out of.
The problem is that it will intermittently surge or shudder between 40-60mph during acceleration. It's hard to pinpoint because it doesn't happen all the time. It seems to be worse if the vehicle is low on gas or the engine is cold but I'm not certain about that. It's not hard enough to call a buck, jerk, or sputter though. Maybe I've over-analyzing but basically it will shift to the correct gear and then back down then back up etc., and back and forth for very brief seconds. Then levels out after 60mph and there are no other problems. If the gas is low or engine is cold is does this in lower gears as well but usually only around 4th gear. I hope this description makes sense.
Here's where I'm confused. The transmission was rebuilt 2 weeks ago specifically the torque converter and rear planetaries. The day we got it back we performed a tune-up so all new plugs/wires/cap/rotor. The fuel filter was replaced about 8 months ago and the fuel pump 2 years ago. All regular maintenance has been performed on time since we bought it 4 years ago. Yesterday the Service Engine Soon light came on and it only showed one code (OBD II), PO161, so we replaced the 02 Sensor (Bank 2, Sensor 2).
However the problem persists and there are no other codes providing any direction. I've tried to search the internet for drivers with the same issue but the fixes vary too much and seem uncertain.
Other known issues for diagnostics: four wheel drive hasn't worked for years (haven't needed it in our flatlands) and ac compressor went out last spring.
Suzuki - Samurai :: 1986 - No Output From Alternator
I have a 86 Suzuki samurai that I have just swapped a vw 1.9 turbo diesel into with a gm 3 wire 10si 110amp alternator.
Wire number 2 is looped back onto the 12v post and has 12v at all times
Wire number 1 is hooked into my dash light.
Key on engine off it reads 0v with the dash light on, key on engine on it reads just below battery voltage and dash light is off. The 12v post is hooked into my stock wiring connected to my brand new battery. Today I had my battery and my alternator bench tested and they both came back functioning normally.
My issue is I'm never reading above battery voltage with the engine on (either from the post on the alternator or my battery). I grabbed a used alternator locally and I was having the same issue. However with that one if I pulled the positive lead from the battery with the engine running it would read 14.3v until I would hook it back to the battery where it would drop back to battery voltage. I was able to repeat that behaviour mutlitple times until I ended up killing the alternator. My other alternator is new and I don't wish to damage it pulling the positive lead but I'm betting it's functioning the same way.
What in my system could be causing this? The truck is pretty old and doesn't have a ecm or much of any electrical and I just can't figure out what's going on. Its like some kind of feedback is shutting down the alternator when it gets hooked up to the battery.
So far I've tried temporarily adding grounds with jumper cables :
Measured 0.2ohm resistance between my ground cable and the alternator housing
Measured 0.0ohm resistance between my positive lead and the 12v post on alternator
I've also tried pulling all the relays and accessories I've added to the positive lead with no change. Camping weather is quickly approaching and I need my truck back on the road!
Ford F-150 - 1997-2003 :: 1986 - Only Jump Start - Alternator?
A co worker gave me an 1986 F-150 5.0 302 with 225,000 miles that he had sitting for 1 year in driveway. He never put the new alternator in that he bought. I towed it to my house and put the alt. in jumped the battery and it started but idle was horrible. turned the idle screw to get bad gas burned off.
Whenever I shut it off or it died from idle I would have to jump it. So, I put new 56-3 battery new relay and it started right up. Drove it down the road to test drive, the truck would want to fowl out whenever I stepped on gas peddle hard. I put Sea Foam and Lucas in the tank and 20.00 premium on top. but now the truck will not turn over since it was shut off unless i jump it but needs jumping all the time. thought it was the starter so, replaced that and still tick, tick, tick, tick when trying to start won't turn over. Its going to start to make me drink, what I can replace now or have checked? maybe its the Alternator he gave me with the truck?
Suburban :: 96 - Intermittent Stalling Upon Coming To A Stop
I have owned this 96 k1500 5.7L Vortex Suburban for 3 years.
Problem: Intermittent stalling upon coming to a stop. When it stalls and I try to restart the engine, the starter can barely spin the motor. The timing is thrown so far advanced that it will literally fire the engine backward and grind the starter gear on the flywheel. I have killed about six starters so far. I took it to the dealership and after two weeks they are clueless.
So far we have replaced: TPS, Ignition Module, Cam sensor, Crank sensor, ECM, and perhaps a few other things I don't recall at this time. If it would stall and simply restart, I could cope with it. The only way I have found to get it to start is when it stalls, pop hood, unplug the power source to the ignition coil, turn key and spin engine over for a few seconds, replug the power source to the ignition coil, and attempt a restart. Usually I don't have to do this more than once or twice.
Suburban :: 87 Start Intermittent / Cranks But No Fire Not Even A Sputter
I have been checking on the automotive forums for Suburban no start problems and have tried some of the solutions, but my vehicle still doesn't start. Here is where I'm at: I have spark, fuel pressure at the throttle body, the fuel pump in the tank is working, new cap, rotor, coil, module, fuel filter, and ECM.
I just ran the truck 2 days ago for 10 minutes to flush the radiator, turned it off to install a new t/stat, then it wouldn't start again. I have tried starting fluid, gasoline, it cranks but no fire, not even a sputter. The pump has been replaced probably 9 years ago. The only other thing not replaced is the pickup coil in the distributor, although the distributor was rebuilt about 10 to 12 years ago. This vehicle just sits until needed, can't afford to drive it daily. The truck is a 1987 Suburban 1/2 ton 350K engine, automatic, 4wd.
Chevrolet - Camaro :: 1986 - Car Dies After Warm Up
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.
Chevrolet :: 1986 Chevy Slow When Going In Reverse
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.
View 7 RepliesChevrolet - Corvette :: 1986 - Vibration And Shaking At 65 - 75 Mph
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?
Ford - Explorer :: 1997 - Alternator Charging Intermittent?
1997 Explorer belonging to a friend who will show up complaining that his battery is dying. Of course, the problem is intermittent.
So far, tried 2 new alternators, (rebuilds), 3 batteries and several diagnostic sessions which have been inconclusive. What I do know is that when the charging system is not working, I still have full battery voltage on the Y/W and LG/R wires on the small wire plug at the alternator. The path from the alternator output through the megafuse to battery + does seem to be intact. Measures full battery voltage and even tried a test by using a battery booster cable to connect the alternator output directly to battery + when the system was not charging.
No change with this test. Visual inspection of the engine to firewall ground strap and the battery - to rad cradle ground wire seem to be OK. Have not had the opportunity to try the jumper cable trick to verify the alternator case to battery - circuit, (darn intermittent!). There did seem to be something intermittent related to a wiggle test in and around the power distribution fuseblock, but once again, this was inconclusive. I also was able to make the charging system fail, (once) by turning on the headlights and blower motor.Any specific failures that may cause this? Not much left to change or check!

View 2 RepliesChevrolet :: 1986 - Oil Pressure Starts Dropping After Driving For A Bit
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.
Chevrolet - Blazer :: 1986 - No Power / Muffled When Rev The Engine
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.
View 11 RepliesCaravan/Voyager :: Intermittent Rumble At Idle - Noise From Alternator
2007 Grand Caravan 3.8L 100K mi. New noise chirp-chirp-chirp Sometimes an intermittent rumble at idle seems to be in synch with the serpentine belt especially when the A/C is engaged. I changed the serpentine belt which did not look bad and did not emit the noise. Noise seems strongest at the alternator when I use a stethescope. I noticed the pulley seems a little loose with the belt removed, but the bolt is tight. This alternator has an overrunning alternator decoupler (OAD) pulley so maybe the loosness is normal. The bearings seem smooth when I spin it with the belt off, and it charges fine. Just the noise is bothersome. Do I need to change out the alternator or just the OAD pulley?

View 4 RepliesChevrolet - Suburban :: Dropping Out Of OD For A Split Second And Then Going Back In
I have a 1990 suburban that has had a rebuilt x-mission about 50,000 miles ago. At this time when I drive there is a hesitation, split second, when running on flat road. It happens when going up a hill, too.My mechanic said change the: plug wires, then the plugs and rotor. No difference.
I think the thing is dropping out of OD for a split second and then going back in. If I drive in 3rd, I don't think it is happening. Isn't there a relay or solenoid that controls this function?
