weird CEL???
ok i got codes p0121 and u0073.
i just unplugged the battery and reset them and they're not on and i drove the car around the block.
i was just cruising on the highway when all of a sudden it just popped up. the car was driving perfectly fine.
i have a Pontiac G5 GT which is now SC'd. i checked my MAF and the intake to make sure no holes were letting air out and saw nothing.
p0121 is throttle positioning sensor
u0073 is the modules aren't connecting properly.

u0073 is set due to a module trying to communicate onto the data line and not being able to output or send a transmission. find out which module is setting the code and whether it's on the low speed or high speed. sounds like a possible open data line wire somewhere depending..

Confirmed. My cruise control has an effect on the code. 90 percent of the time when i use cruise, the U0073 code triggers. sometimes within 10 minutes, other times with in 2 hours. Ideas?
