Truck running rich
I have a 79 courier and I have been going
through gas like crazy.... I used to get
around 25-30mpgs. Now I'm getting like 10-
15.. I think it might b running a little rich
too.. what would be the cause of that ?
Mazda truck and engine.. 02 sensor could be a HUGH cause when was the last replacement?
i dont think its ever been replaced . honestly.. ive replaced just about everything else .. some things twice,, ill definitely look into that .thank you
Perhaps a stuck choke or a soggy carburetor float.
