The mechanic mentioned he kept the original injectors and said he did not use a gasket between the tbi and intake, but rather some special red paste. Injectors appear to shooting well. here's some pics and a video.

Thanks.

Your current TB (OE 17089063) was sourced from 89-90 F-Body (Camaro or Firebidrd) with manual transmission (MT). Make sure that you can connect your transmission TV cable to the TB throttle arm - I saw empty stud without a cable end pointing toward TB. If you have 700R4 trany (aka OD or 4 speed automatic) it must have TV cable connected - otherwise it will fail quickly. You can find explanation on 700R4 elsewhere, but please verify before driving!!

The red 'form a gasket' is Hill-Billy solution - there is a high probably of a vacuum leak and that is causing surging idle. You'll need source a TB gasket - 89-90 Camaro with 305/TBI. There are three bolts holding down TB to Intake manifold. The tricky part is lifting TB up high enough to clean the red poop off completely without any of falling into intake. Alternatively a full disconnect and removal of TB - fuel lines, vacuum lines, and electrical allow for a full access to the top of the intake manifold flange. Fuel lines disconnect require two (2) wrenches to prevent twisting of the fuel lines. Let me know your course of action.



Interestingly enough engine seems to be settling down - did try resetting codes and reconnecting sensors?
