my ute has surging problems when at idle,but this can also be felt when cruising.
Ive recently put in new 02 sensors
new airflow sensor
new leads and plugs
new ECU
new injectors
and ive now come to the end of the line trying to work out whats causing the problem.
it also feels a little boggy on take off also.
Its runs dual fuel (impco system).

does anyone have any ideas they can throw at me!!!

sorry people i havent changed my profile name yet,i dont have this car anymore.
the problems ive got are in a AU2 XR8 UTE

I suggest you do a little tuning of you throttle positioning sensor along with a reset of your base idle. Have a look at one of the stickied threads in the V8 section for a detailed write up. That will almost certainly fix your surging issues.
