1g Throttle Body /Car dies at stop; unstable idle

[Mr96GSX408]

WTH is wrong; i've had a 1g turbo tb on for a while, and this started happening:

... after going home from a drive, i stopped at a stop sign, there is a prelude of check engine, oil, ect. lights that go on before the car dies.

I just cleaned my 1g throttle body yesterday and now i'm really pissed. The car now idles very badly, sometimes at 2000+ rpm's on park after warming up and sometimes jumps to 500-250 rpm at a the stop sign on D. I adjusted the screw many times and its still idles like crap.

also when i slow down from 20mph -0mph the car jerks, like idle surge?

any comments would help.. thanks

Check to see if your shaft seals are leaking.

What did you clean the TB with? If it was carb type cleaner like MCCC did you block of the lower ports? If not your ISC motor might be bad. I would test this to see if it checks out ok. Check BISS screw as well to see if it is leaking around the o-ring and perform any other leak testing to the intake track.

Good Luck
