Sulfur dioxide is the key to this riddle, it seems

I had a truck do this once on I-10. had it towed to the chevy place and the technician knew exactly what the deal was before I finished telling him what happened. he walked out and immediately changed a little piece of wiring harness under the hood and I was good to go within 20 minutes.

turned out to be some wire/plug that was connected to the distributor that apparently was extremely prone to failure. pisses me off that this is that common and GM made no effort to fix it.

About 25 possible issues. Lol but not really! I had this exact issue and changed my fuel pump, injectors, ignition coils, headers, converter, o2's and every sensor and switch under the hood before finding out it was a head leak. Yeah that hurt!

Did you get up to 88 mph. If you did, it is definitely the flux capacitor. I hear they are pretty cheap compared to the fuel they require.

If it is a GM, I would assume it is the fuel pump.

Strong rotten egg smell is unburnt fuel getting to your catalytic converters. You are having an issue with your secondary ignition somewhere. Your plugs are not firing good enough to burn the fuel in the combustion chamber.


Do you understand the point of a catalytic converter?

I'm surprised no one has offered the alternator as a solution. Had mine go out on I-10 and could not get cranked back up. Buddy bought one at napa and helped me change it on the side of the road.

You check the secondary belts- on a cold day a worn out belt might fit perfectly fine on startup or if checked just briefly by a mechanic but become too loose as it expands with heat during a sustained drive.


(such as the one that charges the alternator).

WHEN: Any time your engine is running.

THE CULPRIT: Hydrogen sulfide in the exhaust, which is produced by trace amounts of sulfur in gasoline. It's supposed to be converted to sulfur dioxide in your catalytic converter. This may be indicative of a fuel-injection problem, and can be cured by a sharp mechanic. But often it means a failed catalytic converter. The bad news: A new cat is expensive. The good news is it's probably covered under warranty. Check with your dealer.

Forgot that I changed my alternator and battery wires also.

I had a similar thing happen back in 1989 the morning I was supposed to drive from Stillwater, OK to OKC to take the Insurance Licensing exam.

Brand new Toyota Celica 1 had gotten the weekend before as a really really great deal in Tulsa ($13100 w/all the options available on standard model + 2 dealer bolt-ons usually only equipped on the highest tier model).

Turns out the dealer add-on version cruise control they had run the power lead wire across the engine block and took 3-4 days for the engine heat to completely burn through the line causing it short circuit the entire electrical system.

The Stillwater Toyota dealer nearly got his franchise yanked when he refused to even tow the car in at no charge and I called the regional Toyota rep directly who then got the VP of Toyota USA involved when the Stillwater dealer refused the regional rep. Car got hauled back to Toyota of Tulsa by flatbed and the flatbed brought me a loaner.

My Celica only had 806 miles on it and Toyota values their quality and warranty claims very, very, much, plus I had connections with the Toyota of Tulsa dealership on insurance referrals (that's how I got such a great price deal, they were selling for $18k+ at the time).

Loved that car, around the OSU campus it was a chick magnet. Got totaled in the apartment complex I lived in at 81st/Memorial in Tulsa a few years later. 1 mile from State Farm Claims Office and 8:01am a St Farm claims rep t-boned me pushing the passenger door in to the center console. 1st words out of her mouth were "I'm so sorry", the very thing all St Farm employees tell their customers never to say. Fastest auto claim settlement I ever had too.

I had a mustang do that constantly to me. Changed everything, ended up being the distributor.
