Hello OP here ...
While i applaud your deductive reasoning on my story to keep me
honest , the story is a truthful rendition of what occured
durring the emission test.
the only thing i allege is what i saw, which was a big 20
something on the emission monitor and peeking at the tachometer
that was in the car and seeing it hovering around 5-6k or
there abouts for about 30 seconds (while the tester watched the
monitor) and me realizing that for the 25/25 test it seems he
never shifted out of first gear , next he ground the gears again
a bit and managed to get it into to second for the next test.
I was not really paying attention to the testing until i heard
the engine reving really high, i didn't remember that during any
past test and when he slightly ground the gears i became more
watchful and started adding up all the other stuff he did like
move the tach sensor all around the car and the comment about the
bad RPM made me wonder if the tester guy just flubbed my test or
is it reallistic to think that 1 year and 5400 miles later my car
has gone from clean to enviro-mean,
maybe the emmision machine was reading 2700 when he had it reved
up to 5K ? i do not know but someone probably knows there are
alot of experienced and smart people here.
anyways that seemed like alot of useless fill for my questions
which were... can these emission tester guys muck up the test
like that or do i really need to start looking for the problems
and more importantly what to concentrate on ?
I do appreciate the help.
