I was doing a long drive. Everything great, all of a sudden I merge onto a new freeway so I was going like 40 and I hear a huge backfire, car slowly starts to die. All gauges still ok. Pull to the side of the road, restart the car, fires up like a champ, accelerate just fine, hit 30-ish and backfire and car about to die. Keep gassing it and it putters forward. Same thing happened a few months ago and my mechanic fixed it but I never figured out what it was, he said a carb issue. Waiting for a tow unless someone can tell me what to do.
Ok here is my guess... I forgot to leave out a key part of this story. Earlier today my fan stayed on by mistage and drained my battery. Went and got jumped but the car wouldn't stay on after the jumper cables were disconnected. So I figure the battery is dead (I know, I'm wrong) and the car starts right up and I get on the road. The whole time I am seeing my voltmeter getting lower, don't think much of it. After I posted the first post I decided to give the car another go, start her up and go drive it, no problems! I got back on the freeway and noticed my voltmeter getting real low again. So now I pulled off and this time the car won't even start. So my guess is my alternator commited suicide. Also possible is a homicide, committed by the jump battery. Aaaand, also possible is a mass murder because for some reason my radio and dash lights don't work.
Sounding like an electrical issue now. The backfire makes me think you lost electrical power to the ingition and when the power came back on it backfired.
the backfire is from the tailpipe, I felt it right under my seat. I thought I got shot or something, I made a little pudding stain in my pants I'm sure. I am home in one piece, gonna figure out why the alt died.
ah man a mav on the hook. not the prettiest picture. sounds like the iginition cuting in and out. we need to start with the alt upgrade.
definately sounds like the ignition box cutting out to me also. a fried alt could be causing it to cut out....
All part stores will test alts, batteries, and starters for FREE!!! It only takes a couple minutes at the part store.
Sounds like it might have blown a Fuse or two when you regained power. Could have also caused the Backfire. Keep us posted on any new developments.
It can't be a fuse. All the fuses go to lights or electric motors...none have nothing to do with ignition system
So here is what happened. I extracted the alternator and the harness and took it over to Bryant's shop (San Diego Gear and Axle) and he showed me this: This is the wire that goes from the Alternator to the battery post on the started solenoid. There was a crack in it!! I think it happened when I swapped in the new battery, I must have tucked at this old wire too hard.
