Just got my hc ls1 tuned Code P0121
5.3 heads, lunati nitrous cam, and a built motor. Street tuned with hp tuners.
Car is a 2002 a4 z28. Car runs awesome for the most part. The SES light comes up randomly.
Is this something to look into or is this a dumby code? Car runs great, my wide band is broken so I don't wanna go crazy if it would have any affect on my afr's or timing because the engine is new.
P0121
TPS/Pedal position sensor a ckt range/perf.
The above is the full code. Thanks guys!

Well the check engine light came on again. This time when it pops on the car gets really rich. 12.2 area on my wideband. If I turn the car off then back on it's fine. I also noticed my shift points are above 6500, now the car shifts at 5500 and the car never wants to downshift at all.
