    I just got done cleaning my fuel injectors, putting in new plugs, changed air filter, cleaned my O2 sensors, replaced my MAF sensor, replaced my plug wires and my motor is still shuddering when I step on the gas. Also, it idles a little rough, better than before tho. what am I doing wrong? or not doing?

    What you clean with?

    I'm guessing a sensor or two is not happy and giving incorrect readings. Assuming all wiring is still fine.

    You could possibly have a vacuum leak... Or (horrors!!) a head gasket problem. Did you do a compression check while you had the plugs out?

    Yes , My engine check light came on and it is possible that I may have a vacuum leak
    Just not quite sure how to go about checking for a leak. Also, my vehicle is a 1998 Toyota 4 runner 2wd 2.7L

    Perhaps a coil pack? Easy to check.
