massive idle surge. 2g

[n1ck0sp]

96 gst spyder
Stock turbo ecu etc..
1g cas
Balance shaft delete
1g head and air intake.
Boost leak tested. .passed ;> 15 psi
New tps.

Hard to start. Have hold down gas All the way. Had it stared adjusted the timing.
The markers lined up good until it surged then the marks looked to be half a tooth off?

Seemed to run fine. But during idle it had an idle surge of almost 500 rpm. Thinking maybe a dirty throttle body. Cleaning that tomorrow morning.

I changed the firing order on the spark plugs for the one g cas but did not change the injectors or the ecu from oem firing order.

Tried adjusting the biss screw the o ring is still on it.
Turbo is in great working order no shaft play or oil build up.
I'm wondering if I should switch the injectors around or is there any thing I'm over looking.

first of all do not ever change the order of the injectors. also I assume you do not have tuning software, so you most likely have the tps in the wrong spot. Also not really sure how anyone can change to a 1g cas without software, but maybe it possible. Fix the tps and then move on from there
