I am having a rich fuel problem with my 86 civic 1.5 fuel injection. i had a gas analysis done and i have high CO. my spark plugs are sooty. sometimes i have to hold the gas all the way open so it will run or it will just stall. is there codes to read on the 86's? any idea on what is making my civic run rich and stall out?

 

dont think they had port at that time.
is that throttle body or carb ??

 

it is definintly multi port injection.
