Installed the SOS Big Bore Throttle Body today. Pretty straight forward DIY project. After the install I noticed that engine revs a lot quicker than before . The engine seems more rev happy.
The problem I'm having now is the rough idle. If I rev the engine to 3-4k, the RPMwill drop down to to 300 - 500rpm for a second then goes up 1200k then fluctuates to 800-900rpm again. It will keep doing the same sequence over and over again. I did double check the hoses after the install - maybe I'll check again tomorrow.
Anybody have an idea what's wrong? Perhaps air in coolant hoses? bad 02 sensors? Reset ECU to learn new throttle body?
Thanks for the help guys! :frown:
