It starting surging between 1st and 2nd gear and now a few days later has a shake to it all the time and a loud noise sometimes when pulling out from a stop or going up a hill. We replaced the O2 sensor, #1, and it is worse. We did not reset the computer. The check engine light has been on and off for some time now and the computer reads a "1". Are we repairing the right thing? We also replaced the fuel filter with no changes.

Hi there,

When you say surging, I take it to mean that the rpm varies up and down.

It is most probably due to vacumn leakage.

If you get it only after engaging gear and accelerating, then you need to check the vacumn at the left side of the intake manifold.
