After putting 32K on the $350 '93 300E I have had to put it on jack stands for the last month. Original problem was rough idle, now power, etc. Changed wrie harness, ovp, MAF, plugs, wires, coils, disconnected cat and still had problem. Got new ETA and it was not correct one, so I purchased a running 3.2 with good ETA from a '94 with 100K less miles than the 2.8. Started right up last night. The new problem, no accelerator response. The butterfly valve in ETA will not move while engine is running. I can open it while engine is running by pushing down on one side, the engine surges then dies. Any ideas? Thanks.
