power line killing my car

i have a 99 cavalier and when i drive under the power line over my drive way the engine quits if i drive slowly . anybody hear of this problem before ? if i give it more gas it will usually pickup and go on .
 
Maybe a stray EMP due to a small short??? That is why I hate computers in cars and other such things
 
Could be stray EMF from a bad transformer or something not properly grounded. I had a snowmobile years ago that when riding past a certain point on a power line (main high line) it would backfire, only in one spot, might have been a coincidence due to my speed/throttle position in that particular terrain but I always thought it was related to the HV above me.
 
I would call the power company, & "show them" what is happening. I have a light pole the power company said could never be arcing, or making noise on a dry night. You could physically see the electricity arcing, & hear an erratic buzzing sound. Never told me what it was; but I have a feeling the insulator was cracked, or split. They didn't argue anymore after the power went out at that pole!

You might have to have them raise the wire several feet, or bury it!
 
Actually a good diagnostic tool is the AM radio in your car. Tune it to a vacant frequency and drive around and listen for changes in the noise you hear. Things will probably get interesting around the area in question.
 
No not the Prius.
One runaway was a bankrupt porn site operator that faked his prius runaway to pay his debts and retire on Toyota money. The event recorder on his car showed he had accelerated to speed then rode the brakes more than 100 times to try to burn up the brakes.
The other was the little old lady who swore she was hard on the brakes when her Prius ran away, but the car event recorder showed that she was really hard on the gas from the time she shifted into drive untill she hit the stone retaining wall.

In both cases, the only computer trouble was with the organic computer between the drivers ears.
 
I would say it's coincidental that you car happens to quit under the power line. Are you saying that it only quits under that particular power line and isn't affected by the hundreds of other power lines you drive under? And it never, ever stalls out elsewhere? Do you have to tow it out from underneath the power line to get it restarted?

My wife was complaining that her Trailblazer was stalling every time she made a sharp turn. "Ridiculous", I said. When it quit on our daughter-in-law. it dawned on me what was happening. After switching the transfer case out of four wheel drive, the problem disappeared.

Look for a more reasonable explanation.
 
reasonable you say!!!! I have had problems with my last pacemaker when to close to ground level transformer in friends yard.
 
Does it happen in both directions, if not I would expect it is an issue that comes up in how long it takes you to get there from starting.
 
Possible, but not likely. Modern cars are generally well protected against the effects of electromagnetic fields...in fact, there"s actually an SAE standard for automotive immunity to fields generated by power lines. There would have to be something wrong with the car, or the power lines would have to be producing fields significantly higher than normal, which is also not likely.

PS...with regard to the pacemaker comment below, pacemakers detect extremely small signals, and the body is part of the circuit...kind of hard to shield your body against small voltages introduced by nearby strong magnetic fields, such as might be produced by a high power transformer.
 
My 2012 BMW motorcycle will die at one intersection, unless I keep it at a fast idle until the light changes. Lots of power lines and wires at that intersection.
 

it has been doing this for several years now . not every time but most . car needs to be at or near idle . car drifts past cut off point . sometimes times it just stumbles .if it completely dies its hard to restart . there is cable and telephone also . power line is low at this point . drive way is 200 feet long and it only happens directly under the line .
 
is it just a line off the street to the house? or is it a high voltage transmission line?

if it's just your residential line, I'd think there's something wrong with the transformer - unless the line is REAL low and almost touching your car.

(AND something wrong with your car - a break in the shielding - or maybe you simply need new plug wires?)

A line on the street shouldn't have enough power to cause much trouble outside of a couple of feet.

Those high voltage lines can though. We used to go out shooting near them. If your gun barrel touches you while you walk under them, it kind of burns you. The metal will generate a steady arc against your skin.

Kind of unsettling. Always wondered if it could somehow set off a round.
 
A few years ago in the Allentown,pa area. I don"t remember the motel but something like motel8 or motel6. It was a damp and misty night. As I got out of the truck, I got a shock. I DO NOT mean static!!! I was under a high tension line. I pulled out my digital meter from the truck and ran it to ground, There was over a 300 volt reading on the meter!! Not enough to knock you on your but, but it sure did sting! Jeffcat

I've got a Stanley 'stud finder' that shows wood, live electric wires and metal - one day I was thinking about a story I'd heard about some 'squatters' that were camped out in the desert near a hi-voltage line. The power company was making a helicopter inspection of the line and noticed fairly large circular patterns under the power line and close to the squatters pea patch - SO they sent a ground crew out there to see what was up - turns out they (the squatters) were getting power radiating from the lines and collecting it with big coils of wire which was barely covered with dirt and running their digs off of it! Anyway, about the stud finder - I took it at 90 degrees to the 8,000v power-line over my driveway and it picked up a 'hot wire' as I got close to being right under it - It will do this any where upstream of the pole mounted transformer - so maybe there is a lot more radiated energy out there than we've come to believe :?:
 
Do you think maybe EMI could cause a similar problem in, say, a 1976 Ford LTD?

When I was a kid, we had this 1976 Ford LTD steamboat of a car. It would die at this one intersection about 3 miles from home, no matter which direction you came from. Always this one intersection, never anywhere else.

You could drive it 100 miles from this intersection to anywhere and back and it wouldn't miss a beat. Stop at this intersection, and it would quit on you.
