hey i was wondering if any1 had ne ideas as 2 y my primera would start surging.It only surges when it is held at a constent speed. e.g when im doin 50kms in 3rd gear and try to keep it at 50kms it starts to surg but as soon as i put my foot down it stop or when i take my foot of it stops.

If any 1 has any ideas as to what the problems might be please let me know.thanks

Sounds like a throttle position sensor issue.
