Engine blips

The engine of my 1996 SL320 has started to miss or blip when stopped in gear. It doesn't happen when under power. I have noticed that the fuel pump is a little noisy, and think it might possibly be the the culpert. Any thoughts?

all fuel pumps have a humming sound- and you WILL hear them. Check filters first. Also, check main engine wiring harness for insulation cracking. Lastly, check throtttle body - make sure it's clean as well. If you start changing parts just because you "think" it's the problem- you WILL spend alot of money with no visible results to brag about.

I had it in to the dealer for two days. They can't find anything wrong, but I'm not sure they checked either the throttle body or the wiring harness. Hopefully I can look at this over the weekend. Another mechanic said it could be the throttle position sensor, or the mass air flow sensor. I would think these two things would have shown up on the computer readout at the dealership. I wonder if it could be water in the gas. When the tank gets low I will add some HEET when I add fuel.

a2aa: What year is your 280CE? Mine is a 1978 with 91k. My wife says I need to sell it because it rarely gets driven, except to the German Car Show.

I'm thinking about selling. It is a metallic medium brown color, not dark or light, almost has some red in the color. Interior is almost like new: parchment seats and trim, and floormat, black dash. I put it in Star magazine in the early summer, but put too high a price and got no response. My son drove it in a road rallye last month here in KC. I have thought about restoration also.

restore

seems like you need very little restoration, if any. Just keep up with small thing s that go bad ie: moldings, wear on upholstery, busted bulbs,etc.The most drastic restoration wil be a new paint job. Don't settle for cheap over spray. Anyway, goodluck with the project. Not too many good examples of the w123 coupe gas around. Good luck.
