I had enough and took action. My investment gassaver. My 1996 Geo Metro 5 speed 4 door sedan. It needed a new motor along with a radical tune-up.
It's looking like I'll average 40mpg in the city which is where I do 95% of my driving. I'm trying to burn a few tanks of premium through it along with some Techron fuel concentrate to clean things up a bit, then I'll change the fuel filter and see if regular unleaded will not cause the detonation I was experiencing.
It drives wonderful. No a/c or p/s, but what the heck.
My '88 Escort doesn't have a/c either, you'll be looking at a lot of hot summer days ahead, but like me you'll survive. Could be worse and not have heat in the winter. That Geo is a good looking car though.
Its the 1.3L 4cylinder.
As far as the a/c goes, I could get it fixed, and probably will. Yes it will be a hot summer.
Years ago I had a 1981 AMC Spirit with no a/c and vinyl seats - "The Grey Ghost" It was purchased new by my grandmother and only used for her 10 minute commute to work. She lived in Connecticut so the summers were not as bad as they are here in VA. Also her logic was that she'd be home before it really started cooling anyway. Man I sweat it driving that car. I used to beg my mom to let me take her old station wagon on really hot days. Eventually my sister took the AMC and I was left with the station wagon, as nobody else in the family would drive it. At least I had ice cold air conditioning, and a full size wagon was affordable to drive for a 16 year old when gas was $0.85/gallon.
Check your timing and don't use lighter than recommended engine oil. Also make sure you get some cold air into the engine as hot air will increase knock in the summer time at least. Guess I should have had my 1 liter pulled out of my Metro at the junkyard - probably crushed by now used to get over 50 all the time.
