I have a 1993 300E with M104 and 722.4 transmission... one day... i noticed my kick-down wasn't working... so I bought a new kickdown switch. It DID NOT solve the problem.
The gas pedal is broken and could be replaced... I'm thinking that the variance of not properly aligning (still hits the kickdown switch though) might not be telling the ECU that it's at WOT??? So if gas pedal gets replaced... and still nothing.... where do go from there?

It sucks when going about 8 mph and really need to get up and move... and floor it and just get no power!! Even dumping the gearbox won't get u into 1st gear unless stopped or going slow enough with enough engine load....

Thanks for any insight.
