Hello,
I recently moved from Atlanta to coastal Delaware and need help finding mechanics in the 100 mile radius. My 280SE 3.5 had a lot of work performed by my friend and I over the last year. I replaced the D-Jetronic Wire Harness; Temp and Air Sensors; spark plugs, trigger points, throttle positioning switch; points; wires; coil; ballast resistors; valve adjustment and all 8 fuel injectors were sent out for testing. I also purchased a D-Jetronic tester off Ebay which hooks into the ECU.
After putting everything back together, the car ran very poorly! With the D-Jetronic tester, we were able to determine that one of the fuel injectors (electronic not mechanical) was sticking open. So I found a new one and replaced it. This improved it greatly, but it still has a miss. I ran out of time and ended up moving in January. I brought the car to DE inspection and it failed the Hydrocarbon emissions. I think the limit is 900 and mine was 1300 (but I don't have the paperwork in front of me). I REALLY need to have someone run the car on a scope to determine which cylinder is misfiring. We tested the spark at each cylinder and it was great...the ECU was switched with a rebuilt one and it didn't make a difference. I suspect another fuel injector isn't up to par, but they are expensive and hard to find.
So....does anyone know a honest MB mechanic in DE or near Annapolis, DC, Baltimore or Philly? Wilmington. DE would be more ideal.
I also need to pull one spark plug wire at a time to see if one makes little difference. I've been so consumed with the move that I haven't attempted this yet! Thanks for your help!
