Boiler that irregular idle is normal for 100 to 200 miles til the computer adjusts.i dont use rtv on the throttle body.i used mercedes gasket sealer ,its a little different,and you must let it sit for 5-8 hours,i usually go to sleep and give it at least one whole night.you must scrape and clean the throttle body allow the gasket sealer to sit for a couple minutes to release gasses.then bout 5 mins later install and bolt,trying not to smear any sealer.tightin bolts to specs or there about.reconnect all.and it should act stupid up to bout 200 miles then youre good.when i did mine i noticed a good increase and took the car to dinner at the olive garden she had a good time so when we left the problem was solved and we were friends once again.
