I'm at a loss with a stuttering and bucking problem with my car. It only happens during cruise/light load conditions. My wideband will spike rich and lean and stumble really bad. WOT no problems at all.
So far I have changed plugs , wires , o2 sensor and cleaned my MAF.
NGK brp6s gapped to .028 and NGK wires
I had a Bosch o2 sensor and saw a lot off people had problems with them so I swapped it out for a Denso
My coil pack checks out fine
Right now I think it has to be my MAF but I also read somewhere that a dirty EGR valve could cause there symptoms . My car was burning alot of oil form bad valve stem seals but they are now replaces so I imagine that could of cause a lot of build up in the ERG valve.
Any opinions on other things to check out ? I'm at a lose
No one has any ideas or suggestions?
