distributor cap and such are laying in the garage waiting for me to put in, but ill look into the pcv valve

 

get one from the dealer, but verify the standing of the plenum (leaking or not, or bad pcv) before you replace the pcv.

 

Check for vacuum leaks too. I was only getting about 10 mpg until I found a sizable leak, gained 2mpg once it was fixed.

 

+1 - and whatever you do DO NOT turn the distributor! This will open up a whole new can of worms!

 

Can of worms? You mean another $300 bill...

 

As was stated a good tune up is the best place to start. Also keep in mind no matter what you do to improve efficiency the biggest impact will come from you driving habits.

I was getting an average of 10 MPG around town with mixed hills and flat stretches, did plugs, wires, cap,rotor, and new coil, went up to 12 MPG and with the K&N drop in filter I get a high of 13.5 with an average of 13. I don't drive like a granny but then I'm never really in that much of hurry either, from time to time I like opening her up to let the headers and flowmaster rumble.

Be interested to see what changes if any I see once I replace that clogged cat. Will also be doing the plenum upgrade to in the near future.

At todays fuel prices the extra money spent keeping a vehicle in top running order really is worth it even for modest MPG gains.
