260E floods after warm
Ok, I have read many posts and tried several things to no prevail. Basically, here are the symptoms and attempted fixes.
From a cold start, the car starts very good and for the first few minutes runs like a champ. Once the car enters closed loop, power drops at low RPMs, it runs very rich, and tries to stall. The economy meter is pegged out. From a stop, it is non-responsive, but if you floor it, it puffs a huge cloud of black smoke then off ya go. If you stop, shut off the car, then restart it, it runs great until it enters closed loop again. On the highway, if you keep your foot to the floor is runs great.
What I have done so far...
Replaced the O2 sensor (no change)
Replaced the Engine Temp Sensor (the 3 prong)
Tried unplugging the EHA (no difference)
Changed the OVP Relay (no change)
