Quote__________At the end of April I installed a K&N AF and modified the blow by oil collector to prevent too much oil going to the AF. Reconnect A/C wire(has it disconnected forwinter) and the A/C Comp locked up. Since then I haven't driven it that much(mostly city in the evening)but I have noticed each tank I got about 27 MPG_______

Describe your oil blow by tube mod.

I did an intake mod that some might find interesting. I have a K+N but I did not have the car long enough before doing this mod to get a mileage baseline. The bigger intake did help the pickup up at low speeds.
