Speedometer reading wrong
Okay I have a 2002 Pontiac Bonneville SSEI
on the way back from town my car was
doing 60 then automatically went straight to
90 and I was still at the same speed limit I
don't know why it did that and I can't read my
speed correctly now because my
speedometer saying I'm going faster then I
really am so what do I need to buy to fix this
or what could the problem be to were I can
just fix it
