poor gas mileage
i bought a 1990 tracker, 8v, 3spd, auto, 2 door, soft top, etc..
it sat unused for 2 years before i purchaced due to a burnt exaust valve.
recently i replace the valve and head gaskets and other gaskets that were leaking from sitting. i also noticed that one other valve was changed in the past.
Anyway, with all the valves lapped and good compression, i only get 18-19 mpg. the tracker runs better that before but has the same bad mpg as with the burnt valve.
I set the valve lash and put the timing light on. everything checks out to be right.
Then i noticed that the CEL is burned out.
I am buying a new oxygen sensor today
What else should i check? What else could cause bad mpg?
Is there any special to do to set the timing on my 90 tracker?
