Fluctuating AFR and miscellaneous issues. Please help
« on: August 03, 2023, 03:57:09 am »
At the beginning of the year I replaced my previous blown engine with the same one. TSI with engine code CCTA with manual trans, started having a few issues a few months later which include a fluctuating afr from about 13.8-14.9( i have a wide and gauge). Slow accel from stop and horrible throttle response when revving up to get into first gear. If revved the car will shake as needles drops close to idle. I’m getting lean code and Evap code p2402. I have done multiple smoke tests in engine bay and in gas tank area, nothing. Please help. Feel like I’m chasing my own tail here.
