I recently installed new Bosch 4 hole injectors in my 89 jeep comanche and ever since then it is putting out black smoke and getting black stuff all over my paint! Is there any way to adjust the fuel air ratio so it quits doing this! The idle is kinda funky to since then! Any ideas would be greatly appreciated

Thank you to everyone who replied! I really appreciate the help!

Ok so I have an 89 jeep comanche 2wd with the 4.0 inline 6 automatic trans. I am thinking of buying this 86 jeep comanche 4wd with Gm 2.8l v6 automatic trans! Will the transfer out of that bolt up to my tans or no!

Ok so first question! If your looking down on air filter box, there is a hose bottom left that runs up and under exhaust manifold! What is the purpose of the hose? 2nd question! There's oil getting built up on the top of my air filter, coming out of one the vacuum lines coming from valve cover! What could be causing that, and would it be possible to run a small breather tank with drain C#*@ at bottom to rid of that issue? And 3rd if I were to run a cold air intake, what would have to be done with the vacuum lines, if someone who already did this, have pictures?
