HELLO EVERYONE, I HAVE A 91 300E WITH 97,000 MILES. JUST RECENTLY IT HAS DEVELOPED A MISS UNDER ACCELERATION FROM A STOP. IT WILL ONLY DO IT WHEN IT IS FULLY WARMED UP. I HAVE REPLACED THE CAP, ROTOR, PLUGS AND WIRES. ALSO I HAVE TRIED FUEL INJECTOR CLEANER TO NO AVAIL. THE MISS WILL CLEAR OUT AS SOON AS THE ENGINE REACHES ABOUT 1500 RPM'S. I AM AT A LOSS AS TO WHAT IT MAY BE. IF ANYONE HAS AN IDEA, PLEASE DROP ME A LINE. THANK YOU...JAMES PS. THERE IS NO CHECK ENGINE LIGHT ON AND IT RUNS GREAT OTHERWISE.
I had a similar problem with my 1990 300CE. I found some leaking vacuum lines/rubber tees.<br> Also, try to narrow your spark plug gap from 0.8mm to 0.65mm and se if the miss clears.<br> I also had to replace the fuel distributor.<br>
