Re: TBI woes
It set a lean code more then once and a lean condition fits some symptoms.
Is the three wire oxygen sensor a Bosch unit? If so I suspect it is the problem. I would try unplugging the oxygen sensor and seeing how it runs as it warms up. If the system is seeing oxygen sensor readings that show the sensor is warm enough to use, it will be reaching closed loop operation when the engine is not as warm as it would be if it had a one wire oxygen sensor. Let us know how it runs with the oxygen sensor unplugged.
