i know its not clicking all the time, but it does work.

what ecu are you running? i was assuming this was a FRST, but with a conversion like that, im guessing your running mega squirt or something like that.
which i will be honest, i know nothing about, well very litte not enough to advise anything though.

if you are running a after market ecu, it could be a fault within it causing the problem, or it could be another sensor causing the problem, maf, lambda etc.
without knwoing the full extent of the conversion and checking it my self, theres not really much more i can help you with mate, but it might be worth while popping down a tuners and having it checked and set up
