Have not had truck long I am getting code p0133 before I was getting p0172.p0175,p1131,p1132and p1152 I have changed plugs put stock airbox intake tube back on cleaned the maf put on several new vacuum hoses coils all looked good and tested to within specs. I reset codes now I get the p0133 misses at idle and acceleration. any ideas appreciated thanks
update
I changed the o2 sensor precat on bank 1 it had a p0133 code I also changed the fuel filter now instead of a miss and hesitation at idle and acceleration it shakes like crazy on acceleration not sure where to look next any ideas anyone
