rough driving/ engine knock

[mangvue05si]

so i have a 2002 si, with 50k on it,
i just installed CAI, TEST PIPE, SKUNK 2 EXHAUST

the other day i was driving and the CEL came on,

checked it and it was knock sensor malfunction and TPS malfunction.

i replaced the knock sensor only and the CEL was off,

a couple of days laters the TPS came on,
then off later on that night.

the CEL comes on and off..

im sure its just the TPS thats making the CEL go off.


NOW when i drive, from 1k-2.5krpm it cuts off the acceleration even though my foot is on the pedal,
then when it "reads or senses" that i still have my foot on the pedal it jerks as if i downed a gear and then continues to drive fine.

with my foot down all the way (on highways =0) it doesnt do it

it idles at 0 mph fine,
but when i put a steady pressure on the gas pedal, it bounces from where it should be and down
ie: 1.5k----1.2k----1.5k-----1k-----1.3k-----

kinda roughish and VERY ANNOYING

I JUST WANT TO MAKE SURE ITS THE TPS AND NOT ANYTHING ELSE
(like the test pipe)

ANY HELP IS APPRECIATED THANKS PPL!
