SL/R107: 560SL Almost stalls then ok.
The vehicle always starts fine. When i put it in gear and press the gas pedal the RPMs do not increase and acts like it is going to stall and sometimes it does. If I put it in Neutral and press the gas pedal it runs fine. I can then put into gear and drive and it runs normally. This is intermittent. Any suggestions on might be the problem and corrective action? This happens when engine is cold or hot.
Thank you.
