    i just recently swapped a 99 SI motor into my 96 LSI coupe (euro spec dx, with ex luxuries). the swap was succesful, but i am having problems.

    when i try to keep the car under 1-3k rpms, the rpms sputter (go up and down, over and over) it almost sounds like i'm doing it on purpose. i have to give it alot of gas just to get it going. and it happens in every gear when i go below 1-3k rpms?

    i was told maybe my TPS was bad, but i am not sure? just hope it's not expensive!

    are you throwing codes?

    what ecu are you running?
    what wire harness?

    and what does the euro spec dx consist of?

    is your ignition timing set correctly?

    check for vacuum leaks
