Car was fine no ses light, changed sparkplugs and oil filter and oil, also filled up the tank and my fuel gauge doesnt work, https://www.youtube.com/watch?v=s-1B...ature=youtu.be Video shows on a continuous acceleration the needle jerks, have a code for Crankshaft position sensor A. Maf says it is pulling anywhere from 4.5-7 g/s while idling at around 800rpm, everything is stock as far as i know, 1999 camaro rs 147k miles/

 

also had code for Running lean on bank 1 & 2 but i cleared them and they havnt come back on yet but i havnt drove it so they may come back.

 

i would suspect the crank sensor. check crank sensor wires and plug for damage
