93 190e won't run help pls
 

Here's the story got this car a month ago it was a hard to start car meaning it cranked for about 5 sec before starting, when the engine was cold it would run fine with hesitation from start off, but after warmed up the it would have a hesitation at start off after about 5 minutes would run fine and would only come back after the motor was shut down and started back up. The other day I got stranded in a parking lot I came out and the car would actually fire right off the bat, but would die immediately if starter fluid is used the car will run if you keep rpms high other then that it just fires and dies thats were i am now. I have checked the overvoltage relay and the fuses are good. Any thoughts on were i could go from here?????? pls help

Check for some serious vacuum leak. Check the rubber hoses that connect the IACV to the intake. Also check the rubber boot betweent the AFM and the throttle body.
