oscillating idle when warm

nyc212 · Mar 27th, 2013, 12:35

hey all,

i have had a BRC system installed on my '05 v50 t5 installed for almost a year and still get from time to time an unsteady idle. different from most post's i have seen here, my unsteady idle occurs when restarting the car after some use and the car is already warmed up. when it switches to lpg and i press the brake then put it into drive is when the oscillating begins.

i told the installers to change where the lpg takes the vacuum further away from the brake vacuum. this did improve it.

any ideas?

It is to do with engine loading. I suspect if you also turn the steering it will have and effect on the idle.

They should be able to altering the mapping in that one area to solve the problem.
