R33 Gtst High/low Idle

[chrisdicko23]

I recently had some work done to my car and ever since then my car has not been idling correct. the place that did my car said that i hooked up the boost controller incorrectly. the way i had it was having the boost line from the fuel pressure instead of using the line that connects to the blow off valve. so they changed the boost controller to connect to the blow of valve line and ever since then its been idling at 1100 rpm. so i adjusted the throttle and the screw for finer tunning and when i get it to a spot im happy with i drive the car and it will either idle high at 900-1100 or drop to 400-600! it has also been stalling from the low idle! i cannot work out why i cannot find a correct setting unless somethings hooked up wrong or the ecu hasnt had time to adjust to the new settings? What do people think?

Hey bud,

Have a similar low idle problem, its usually the bov, I have a greddy profec b and you can adjust the pitch and what not.id suggest you go revise your bosst controller setup because mine, the lineoff the boost controller ts onto my boost gauge line which is then td off that small fuel pressure line near the vvt connection. Then I have avacuum line going from top ic piping to the in on the greddy unit, then the out line goes to your waste gate right near the turbo, make sure you hve removed stock boost controller located near the power steerjng fluid resevoir and I just taped up that connector that you take off the stock b controller.

Hope this helps bud!.

As above, I was having similiar issues.

I ended up blocking my BOV with a coke can (cut up to seal it) and it worked like a charm for a few months now.
