What else to replace with injectors?
I have recently acquired my grandfathers 89 corvette with 34000 miles. It has sat alot and just road once a year just to get a sticker. It has a rough idle and even stalled once but not all the time sometimes its smooth I have replaced the fuel filter twice, and have seen where he has had 4 fuel pumps put in chasing down the issue, also it does have new plugs and wires. I have also seen where the local dealer cleaned the injectors back in 2001 and he said he always put cleaner additives in the tank. I'm pretty sure between them the multitech are shot I haven't tested but I plan on riding the car on long trips. But my question is I'm going with bosh 3s from fic and getting all gaskets seals and o rings new fpr and egr is there anything else I need to replace while under there?

Take off the throttle body and clean it. Take off the IAC, the IAC housing and the plate on top. Clean all the passages and do the coolant bypass. Use THIS to replace the IAC housing.
Call TPIS since their web page is FUBAR. All new gaskets, of course.
