I am having problems with me E420, Like most with idle problems I believe my ISC needs to changed, I read that some people found a place that was selling this unit for cheap, well cheaper than the dealer. Can find the post anymore, wondering if anyone can point me in the right direction.

Problem: car idles at 1000 rpm all the time, at sometimes after coming to a stop and putting the car in park or neutral rpm would fluctuate for a few seconds and then again stay steady on 1000.

Work done: new cam and crank sensor - cleaned out EGR, tested working. - New wiring harness - new plugs, distributor etc.

- Also someone said you can open up the ISC and check the board and re-weld the solder that is causing the problem... anyone know about this??

Thanks
Nick
