As you all know, I recently purchased an eBay 560SEL. It had a new muffler, pipe, cat installed today but now it dies intermittently.
It happened about 5 times today and it's random. I start her up and in about 6 seconds the engine goes to idle @ 600rpm. Without warning, the revs start to drop to 200rpm then to 0. The scary part is this happens while I'm driving in traffic on the road. I can't tolerate this thing just dying without warning whilst driving.
I started her up again and made sure my foot was on the gas and give her some good revs to 3000rpm and I was able to drive it to my home (10 mins. away)
What could this be. The infamous FPR issues? Distributor (rotor, cap) issues? Running lean perhaps? Spark plugs or wires?
