Help!!12mpg and errror code 25& 26
Looking for insight,
Just drove from Georgia to Nevada in 89 22re 4x4 truck with 31x10.50 and need to fix problems before I drive back in a few weeks.
Before I left I did tuneup and new o2 sensor since I was getting CEL error codes 21(o2 sensor) 25(fuel rich) 26(fuel lean). After that CEL remmained off but had poor mileage 12mpg-13mpg. 900 miles into trip CEL came back on only for codes 25/26. Power cutt out and had to keep it floored to do 60mph at high altitude. Any ideas? vaccum leak? egr? Don't want to drive home 3000 miles with 13mpg highway.
thanks and Merry Christmas
