You have to check the lambda reading (mixture) now, will change after replacing EHA.
It's sounds like the mix is now lean, you need a MB test cable and a Fluke meter to perform this procedure. Abit risky but you can also remove the ball from the lambda tower and with a 3mm allen push down and turn a ever so lightly clockwise for rich and counterclockwise for lean. Just remember to turn extremly small amounts untill its idling smooth. Do a search for Lambda adjust and procedures. Oh, don't fool with the brass screw on the EHA!!!!
