1988 300E. Hi guys, yet again another problem. I know my ovp relay is not working correctly because sometimes the abs light comes on and the idle goes low, then the light shuts off and the idle goes back to normal. Well, I ordered a new relay, the new one with 2 fuses and when I go to put it on the car won't stay on. It stalls as soon as it goes on. I take it out and put the old one back on and it starts right up. Although at one point it didn't want to start when i put the old one back on, i had to tap the idle control valve. I know i'm gonna need that soon too. My question is, do you think the relay they sent me is bad. I ordered the kae 3.901.300. My old relay is 201 540 3245. Could it be the wrong relay as well? I checked everywhere and this is supposed to be the replacement. Any advice.
