      when you checked the timing. did you short the blue_x000D_
      connector first? then start the car. then check it with the timing_x000D_
      light.

          Emissions failures with poor acceleration and no check engine light I would actually be checking the mechanical timing, if your timing belt jumps time it can exhibit those symptoms.

                this goes to show no CEL code don’t mean you don’t have a sensor problem. this is the very reason i like to see live data when some one has a issue with no CEL codes. _x000D_

                  On pre 96 cars this is true but post 96 cars not so much as the parameters for setting a CEL are much tighter than they were before 96._x000D_

                  If it’s a post 96 vehicle with no codes there is little reason to go loo

                    You and eric are talking about 2 different things…you were originally mentioned a sensor problem with no cel…eric is saying that is unlikely after 96 (which i agree). The fuel trims have to be a certain reading before the cel light will set…its also

                        There are no absolutes in auto repair you mostly play the odds based on the evidence and your experience, not just yours but sometimes the experience of others hence the reason this forum is in existence.
