!987 260E
The car will not run with EHA plugged in. If I unplug the eha and tune the vehicle for best idle I can run it all day, as soon as I plug the eha back in the car stalls. If I tune it with the eha it idles fine but fouls out the plugs in less than 4 miles.
I've changed the FDU, eha, temp sender, idle motor,cap, rotor, wires, EZ unit and ovp. When I try to read the mil amps on the eha I get a constant .059 readout. Also I don't seem to get 10volts at the cold start injector. This is why I am now wondering if the cis-e ecu has gone bad, even though I get different results when I either plug the eha it in or unplug it.
