i have an 84 190e 2.3 8v and everytime i start my car it usually takes a couple of times of turning the key, i could hear it trying to start but it takes a couple of times and once it starts, i try to warm up the engine by revving my car and i step on the gas and quickly hit twenty on my rpm gauge, it looks like it is about to die and sometimes it does and have to restart the car, and after a couple of minutes of warming up, it is okay and after when im driving and reach my destination and put it in either park or neutral, my rpm goes up to 15 when usually it is like around 9 or 10...thanks for any input

Check your overload relay,is right behind your battery with a red fuse (10 amp)at top.
hope this help.

thanks for the info, it helped...it reduced the rpm idling back down to around 11-12 but i still have a hard time starting and sometimes it doesnt have that dying out sound when i step on the gas, thanks again and i would appreciate any other info you might have...
