Car stumbles sometimes on full throttle. Changes fuel filter with no change. Could this be a bad sensor or does the car need plugs or something else?
Do you

Ok first off does this car have a rev or speed limiter? This is usually set at the factory. Next thing would be to test the TPS (throttle possition sensor). If you have a digital multi meter we can test it to see if it is bad.

Don't think it has a limiter. I've relined it beyond 7K. TPS test should read near zero volts on the signal wire up to 5 volts at full throttle. Is this correct? Did not scan a code for TPS.

Ok the tps should be around.5 to.8 volts key on engine off throttle closed and at open throttle it should be 4.5 to 5 volts.
As for the P0332 code the knock sensor this can cause all kinds of issues like pinging and bad mpg. To check the knock sensor unplug it and use a multi meter set to ohms and check resistance between pin one and ground if more then 10000 then replace the sensor as it is bad.
