I doubt the gas was bad because I am still on the same tank. This lasted an hour.
My smell does remind me of RTV. They are rehabilitating an overpass. There was a tent over some of the lanes (closed) on my side. I was in the open lane closest to the tent.
Will pollution of the O2 sensor cause the engine to miss under extra load. And will it go away after an hour?
The engine was not turned off until the symptoms were nearly gone. They were totally gone the next morning.
The battery is under the back seat. The alternator was also replaced at the time of the soaking because the regulator had failed. Also, at that time, a leaking heater hose elbow, one coil, both fog lights, and one headlight were replaced (probably the bulbs failed due to the failed regulator).
I never even had a check engine light during this. I checked all the instruments for abnormal readings when the engine was missing. There were none. I will have the codes read tomorrow.
