i'll try to describe this the best i can. i turn the X on, and it sounds like it's choking. like, not getting fuel or air or something. and when i accelerate, it seems to choke it even worse. i had it dyno tested and they said the TPS was bad. it said it wasn't working at all. and it was looseing power insted of adding, like working backwards or something. i replaced the TPS and still not working. like i said... it's hard to explain.
