ML320 Check Engine light
Hi Guys, I have a 2003 ML320 and last night while I was driving home the "Check Engine" light came on 
Could somebody tell me what the causes might be? Another problem it has is that sometimes the engine won't change gear, say I stopped at a light and then I step on the gas pedal, the engine won't change gear, it is stuck in first gear some times and it the RPM can go all the way up to 4000 and still it won't change gear. I usually have to pull over for a bit and turn it off and it works fine after that.
Sometimes it takes lot more RPM to change to from first gear to second. Mind you the truck is automatic. Any help would be appreciated.
