running rich, very rich
I am running extremely rich and have tried everything that I know of I have checked the map,coolant, and O2 sensors and all are good I have also replaced the thermostat just to make sure that the computer is going into closed loop when off. I reset the ecu and after two ignition cycles the ecu shows a code 6 ect sensor. also I always get a code 73 random misfire cyl 3 only when i put the car in rev. I personaly think that I have an ecu problem any sugestions would be helpful.

check distributor for code 73, for the code 6 change the ECT

Re: running rich, very rich (temp)
the ect checks good at 291 ohms of resistance specs call for 200-400 ohms. changed the ecu with a zdyne from hasport and no more misfire code the only thing left is the code 6 tasted the wiring this morning with my fluke meter and i believe that I have a short or brake in the wiring it only reads at .86V at running temp should be at approx 5V. thanks for the reply. found some things at work on the snap on shopkey that helped.
