    Clock Volt meter/LSPV Delete/Hyundai 16’s/FP gauge/after 9months of wrenching ZERO oil leaks
    Yall probably saw few of my threads 96 2RZ auto 2wd
    Basic reason for work was to concur the ‘dreaded hot no start’ condition

    Work done:
    Cleaned TB
    Cleaned intake/plenum
    New injectors
    New cups

    taco runs freakin awesome (big difference)
    Idle started high, but after days of idling and short test drives, ECM learned and idle is fine

    took out for 30min drive
    The hot no start issue appears to be fixed!!!
    Started 2nd crank after 15mins after driving

    but
    CE came on P0172 during drive

    Other factors
    No CE lite for front O2 sensor since I took possession of taco
    MAF cleaned
    No exhaust leaks
    FP gauge reads 47lbs when running
    FP gauge reads 30lbs after 10 mins


    Is this as easy as RR’ng the coolant temperature sensor on back of head?
    Thanks

    Now I got 2codes and front O2 sensor is listed as ‘causes’ in both codes

    RR’d front O2 sensor tonight
    Weird dead zone gone
    Did my normal test drive trip/route
    (Which throws a code every time)
    NOTHING!

    think I’m out of woods
