Well I cleaned the MAF sensor and it lived to drive another day. I did not use a spray. I used a contact cleaner pen from Radio Shack. There are 2 parts to the sensor. First there is a metal rod in the middle of the tube. It was covered in black soot just like the rest of the insides of the sensor. The wire in the back was a little more delicate. You really have to be careful with it because it is very thin. If you don't have very steady hands I wouldn't recommend using on pen on the wire. A lot of light and a magnifying lens made the job easier. The wire was also covered in the same black soot. When I was done it both the wire and the rod came out nice and shiny.
I decided to experiment by removing the upstream metal mesh screen on the sensor. I had already removed the down stream screen.
I'm not going to claim any performance improvement because everything is seat of the pants. The car now pulls very strong from idle. The when accelerating, the torque converter will stay locked from 1300 RPM in third gear unless I punch the throttle. I don't know it this is related to the cleaning or removing the screen. Either way i like it.
The negative side effect is that the car will some times stumble at part throttle when the revs are that low at about 50% throttle with the torque converted locked in third. Its easy enough to avoid that situation. Give it more gas and it unlocks.
The positive side effect is mileage. My last tank returned 28MPG mostly highway at 70MPH and some city at sea level.
I recently installed a cold air intake, Bosch platinum2 plugs and an Ecotek valve from a friend. I use 87 gas.
I want to go through a few more gas tank fulls of gas to establish a reliable MPG average.
Thanks for listening
