Just wrapped up my 4th tank of gas and finally broke 40 MPG. Here's what I've done so far:
- New distributor cap, rotor, correct NGK plugs
- Oil change
- Lowered 2" (by previous owner)
- Converted back to stock intake with K&N filter
- New OEM-replacement exhaust from manifold back, installed correct VX manifold, previous owner installed a DX manifold and 2.5" piping
- Cleaned throttle body and plate
- Replaced all vacuum hoses
- New MAP sensor
- Set timing to 12* (or the red line on pulley)
- Idle adjusted per service manual
- Tires inflated to 36 PSI
Any other suggestions? to help my mileage? I think this next tank will get mid-40's since last tank I still had the cold air intake on there for a part of it as well as the old MAP sensor. We'll see how it goes.
