    I'm getting a hesitation on take off through my first few gears. Checked the plugs they look good. It's on a 06 Tacoma

    Is it harder to start when hot? Could be compression.
    Is your air filter dirty?
    How about your fuel filter? I've heard these trucks are notorious for the fuel filter degrading and then clogging the system. Lets hope its not that.

    Replace plugs with oem denso coppers.
    Dump and replace fluids
    Fuel pump and filter are in the gas tank, leave that as a last resort imho.
    Replace air filter
    Remove negative battery wire for half an hour
    Clean maf sensor
    Clean throttle body

    Maybe u got crap gas?
    What do u mean plugs looked good?
    What was their gap?

    Plugs where gaped at 35 I changed them to 44. There NGK was told they had just replaced them not to long ago. I was checking to see if maybe one was loose.its got 135000 miles and cold air intake. My next step was to start playing with the fuel system. To see if I can get it to smooth out.

    Get a pic of the intake for me

    Is this a 4 cylinder or the v6?
    Those gap numbers dont sound right for the 4.0 v6......
    44 sounds off a little even

    U sure they are the CORRECT plugs?

    "Not long ago" means nothing in the world of used vehicles, esp in the 4.0 v6, those should be replaced at 30K.

    It is the V6. What's the best plugs for it? And at what gap should I run them? Intake looks clean. It idles perfect. Only get the hesitation when I accelerate from a from a stop. Acting like a vacuum issue.

    I have '05 w/ 295K miles just started with acceleration hesitation. You mention clean "maf sensor and throttle body"? Can you elaborate? My mechanic skills are limited. Thanks!
