My 90 GXE has approx. 116k on it. I say approx. because it also has one of those wacky odometers on it and has actually rotated backwards a few miles.

Anyway, my problem is while driving and accelerating lightly, the car sometimes shudders. If I take my foot off of the gas and then accelerate again it seems fine. Also, if it shudders and I press the gas harder it will clear up.

I don't know if it is something in the trans itself (torque converter) or some type of electronic problem.

Has anyone also had this type of problem? Any input is greatly appreciated.

Wheels, see if you threw a weight off. rebalance them.

have you replaced your O2 sensor yet?
how's your gas mileage?

both are indicators of a dead/dying O2 sensor.

One more thing to check is the throttle position sensor. They are often found out of adjustment, or need to be replaced. They are easy to adjust, just loosen the front screw and rotate it. Not sure what the correct voltage should be on a Maxima when you test it, so refer to a service manual for that. Good luck.

I don't think the O2 sensor has ever been replaced. I can't check my mileage because my odometer only works when it wants to which is not very often. The speedodometer appears to work fine.
