Question Timing/low end bog.

I am a newbie here so dont burn me too horribly. i just purchased a 94 Legacy sport with the ej22t. The prev. owner just recently replaced the timing belt and water pump. He states that the timing is off, which would explain the lag in acceleration and also the feeling of misfiring with a bit of backfire on the very rare occasion. I have searched the forums up and down and cannot find anything on how to correct the timing if it is off any. Also wondering if these symptoms could be the result of a bad catalytic and/or O2 sensor right after the turbo.

any help would be great.

The timing belt could be off a tooth.

so once the new belt is on there is no way to adjust the timing other than removing the belt and moving it a tooth correct? I havent hit it with a timing light as of yet so i am not possitive if it is in time or not. I am new to the H layout so i am not really sure as the correct procedure for timing.

The spark plug timing is controlled by the computer. the valve timing is set by the timing belt.

If you pull the plastic cover off the front of the motor you will see the timing belt. there are marks on the cam pulleys and the crank. These marks are what you use to align everything.

The marks/dashes on the crank and cam pulleys should all be straight up. you may have to rotate the crank to line them up. Keep in mind that the ARROWS do not mean anything.

Hope that helps

so i located the problem. Idler pulley was not installed correctly. the pulley that rests up against the tension piston was not on straight, causing wear on my new timing belt. ive pulled the pulley, am realligning the green dots/notches with the notch in the housing I.E. straight up, and lining the crank pulley straight up as well. We'll see how it all works when it's all back together.

thanks for the help.
