1979 300 SD strange problem, car stops after 30 minute driving
Just bought a 300SD 1979, perfekt shape, but with odd problems. The car starts, runs and accelerates perfectly, but after about 30 minutes driving (both highway and town) the gaspedal does not rev up the engine anymore.If I stop and floor the pedal in neutral it barely revs up and finaly the engine dies. After a few hours (maybe shorter, I always picked it up later) it starts and runs like nothing happend. This happend now for months and it is not getting better! I restored a 220 D from 1972(No electronicstuff)!! but the 300SD is a very complex car in comparision. Any Ideas anybody? A mechanic told me to remove the gas-cap and drive, because of some blocked fuelreturn line creating a vacuum in the gastank(?) but it did not help either.
2nd QU: My AC(newly refilled )blows only superHOT, no matter which temperature I dial in. Any clues someone?
3rd QU: I always read about vacuumpressure(hoses,..)What is this vacuum for? and how and where can I check if the pressure is right? Thank you everybody for ANY comment.My Car has been registered and insured since July and I drove only 100 miles.I am very frustrated, please help. Any affordable specialist in New York City?? Thanks for all Comments, Mexx.[:(]Your text here
