Did a throttle pedal dance, developed a
P010B Throttle -“Mass or Volume Air Flow “B” Circuit Range/Performance.

Changed MAFs due to one reading .20v off

Switched TBs, entered high idle, pedal dance gave me a smooth idle again however it still feels slow. Like many here I an extremely slow acceleration which goes away after 3500RPMs. From that point it revs up but not "tire breaking pull" like it should.

Have not driven it since, it does have broken flex pipes with a decent exhaust leak but after AF and O2 sensors.
