Hi! I own a '93 320CE and was very satysfied so far. It is equipped with 4-speed automatic gearbox. Few months ago I noticed that sometimes, when I want to accelerate hard from low revs, car has something like a small missfire and when it picks up revs (from 2000rpm) pulls hard to the red line. I thought it must be something with plugs or so and didn't take it seriously. After I replaced the plugs and checked coils and wires I was fine for a few days. At least I thought so. Then it happened again, and gradually became much worse over the time. I was at different mechanic shops since then but none of them could find what was actually wrong. As previously mentioned, the car gradually began to missfire more and more and now I'm driving it very slowly with very gentle acceleration. This way I don't have missfires but I'm taking about 25-30 sec from stand still to 60mph! Now, I would like to point out that some shops say that the problem is strictly electrical (ignition problem) and others say it is not neccessarily so. They say it has something to do with a fly-by-wire throttle and a fuel supply and not the ignition. My throttle is partly mechanically operated (can be opened 20% mechanically) and partly fly-by-wire(from that 20% till WOT is managed by fly-by-wire). So I don't really know am I experiencing really a missfire (ignition) or it stumbles on acceleration because of lack of fuel? The only known way left to me to solve this problem is to take the car to a Mercedes dealer. I know they will repaire it for sure but I don't know weather the cost of such repair would be greater than a value of a '93 car! If someone experienced similar problem help would be greatly appreciated! Thanks Mario
