    Default 4age slightly down on power and hesitating in lower rpm

    Car - KE70

    motor / part in question - 4age

    problem - low on power, feels doughy and hesitant in low rpm

    occurs/started when (if applicable)- in low rpm below 3500

    hey guys

    Was driving the car home from work the other day, and progressively throughout the drive it began feeling a little dough and hesitant in the low end. it also feels like it hasn't got 100% power, more like 75%-85%. At idle its a little lumpy, but not massively. i've changed the plugs, and it hasn't done anything. i feels as if its not running on all cylinders cylinders.

    I tried the trick of taking each spark plugs lead off to see how it changed the running of the engine. The first one(closest to the rad) was fine, as soon as i took it off the engine started to die. The second one seemed like it only affected the running of the engine a little bit, and got only slightly better when i put it back on. The third one was similar to the second cylinder but a little. when i took the fourth plug off it was the same as cylinder one.

    Tried the head gasket leak test where it checks for exhaust gasses in the radiator system. But that didn't come up with anything. I have a feeling that it might be a break in the head gasket in between cylinders 2 and 3, am going to get it compression tested tomorrow.

    Can you guys think of anything else it might be? i know its got spark to each of the cylinder and it seems to be getting fuel fine.

    any help is much appreciated guys

    cheers
