    97 3.4 4Runner
    None
    So I replaced Coil Pack, Plugs, Wires, Fuel Filter, PVC & Grommet,TPS, AIC, MAF, Vacuum Hoses and Air Filter on my 97 w 3.4.
    Cranks right up cold but after warming up it bogs down when I initially step on the gas then has no problem accelerating.
    I'm thinking the Temp or O2 Sensor could be bad.
    I had a 172 code but it hasn't popped up since replacing MAF but
    I haven't driven the vehicle long enough to recycle just disconnect neg on battery to clear code.
    Should I focus on the Temp sensor next?
