1986 190E - Car starts ok (a little hard), but when you step on gas it wants to die before rpm's come up. But if you disconnect wire to themperature sensor (bosch 547 wires gr/r and gr/blk) there is no lag but idle is rough. Does anyoone know the OHM value for this sensor or is there another problem.

The way to evaluate the temp sensors affect on fuel control is my monitoring the eha current.
