well the car is running. not rich as it was before. now when i pulled into the driveway yesterday the afr gauge read 17+ until the 3 lines indicated it was over 18. Unplugged the oxygen sensor and no change. while cruising the afr will move in and out of 15 and 17. it does go to 11 when i am in boost. timing is dead on base timing set to 10 degrees jumpered. 12 degrees unjumpered. what could cause the car to run lean while cruising or at idle. Now today i went out in the garage and started the car and what do you know the car is back to the running rich idle. 12.4 on the afr gauge. I just dont know about this car. it could be that the intake manifold gaskets are causing a vac leak but i highly doubt that. what could it be
