I still think my highway tps is just that bit higher. It was 22/23. I barely pulled 38mpg on a highway trip of 35 miles. I used to easily pull 40+.

Since I'm going away 4 hours south for college in about a month and a few weeks and taking my car with I'm getting some minor things done.

I'm hoping I can get all this done over the weekend.

Front rotors are apparently shot (according to dad). But then again, I feel it too when I brake above 30 mph.

Tensioner. We broke that. I'm hoping if I have the mechanic replace it, he can figure how to get the belt to fit a little tighter. 61.5 inch belt + bigger idler pulley on the tensioner. Still squeals on start up.

Fuel Filter. Cheap part, it's probably original. Maintenance item.

PCV Valve. Cheap part, etc. Could help with idle.

Then possibly clean throttle body, air flow sensor.

Also, if it's the problem. Replace parking brake cable. The parking/ebrake doesn't work and never has.
