How to use Sea Foam Spray on an engine with throttle body injection? [SOLVED]
1 Answers
I have a 1988 GMC Jimmy with throttle body injection. Is it best to just spray down the throat like a carbureted engine? Engine is a 5.7L 350.

Hi Terry. Yes, a throttle body injection intake form the late eighties is not going to have a mass airflow sensor (like newer fuel-injection engines), so works just like a carburetor intake where you can spray into the throttle valve opening without having to put the air boot back on.
