    hello TW.....i am having some problems with my taco:mad:......when i purchased it, it was in-need of a new MAF sensor, and also had a lot of spark knock. and i do mean a lot. so i buy the new MAF and install it and instantly the truck runs much better, but i just noticed today that i still have some spark knock at lower rpms, and it is still taking my truck a good while of cranking to start up. What can i do to get rid of this aprk knock, and get quicker start times?

    just put new plugs in no more than a month ago, yes the cel is on but i think i remember him sayin it was the o2 censor or a bad cat.....he said we nee to cut out the 2 cats and put in one longer one. This truck really dosnt run as smooth as i thought it would.....I mean for god sakes my jeep ran and idled, and even started faster and easier than the taco!!!

    it takes more than an o2 sensor to do that because mines messed up and i have no cats but i do have a urd sim. but that should not cause it to run bad i would check plug wires or have the cel looked at again to double check.

    i dont think my cel has anything to do with my spark knock or start up issues. as you said earlier its probably somewhere in th wires ir something......im thinking about looking into msd ignition and redoing the whole ignition system.

    Take it to the dealer and ask them to reset the timing. Had something similar with our SC-300 Lexus. The timing was too advanced. When they reset it, the problem went away. If I remember correctly, ours was supposed to be set at 13 degrees before top dead center and it was set at about 21 degrees.

    Curious, why do you need new ignition parts?

    The procedure for timing a 2.4 can be found here:
    http://www.yotatech.com/f2/tacoma-ignition-timing-29107/

    I saw somewhere else a very similar procedure for the 3.4 V6 so the 2.7 should be identical. Trust me, check and set the ignition timing.

    I have been researching this some more. My problem is my 2001 2.7 Tacoma is located in Atlanta and I'm in Texas so I can't just go out and look at what I have. It seems , at some point in the Tacoma line, Toyota switched from distributors to a crank firing sensor and coil packs on the 3.4 V6. Not sure about the 2.7. I can't seem to find any info for adjusting the crank firing sensor and coil packs if that is what you have. I appreciate your frustration, so I'm trying to find you some reliable information.
