i have a 91 190E 2.3 it starts fine runs/idles perfect for about 10 seconds then the rpms drop so that it stutters for about 5 seconds or stalls, if it does not stall it idles back up and runs fine. The srs light is on i remember reading on a post that the srs light affects the ovp relay somehow, but it was vague and didnt say much more. The srs light has been on since i have had the car and the stutter problem just developed. i tried to read up on the ovp but really couldnt find anythng that related, any ideas would be great, thanks
