I know this topic has been covered in other posts, but I have a particular problem that I cant seem to find the solution to. My 1990 300E 2.6 struggles and sometimes stalls on cold start. My cold start valves seems to function just fine. Tested with 12v. My 7th injector seems to work as well. I removed it but still left it connected to the fuel line and connected 12v to it and sprays nicely. I replaced my OVP again. No avail. Replaced the following items last year as well : coil, dist cap, plugs and wires, fuel filter, serpentine belt, belt tensioner, coolant temp sensor (2 prong) any help to my problem would be greatly appreciated. Otherwise to the dealership I go 😅
Thank you!
