hey,

today i changed my fuel injectors and when i took out my upper intake manifold and thorrle body i noticed it had alot of oil residue... is that normal??? after installing my injectors i installed everything back together and turn my mustang on and alot of black smoke keeps coming out. anybody has an idea why? new injectors are stock

it ildes lil high but still engines runs good, can it be that i didnt connect a hose?

it could be fuel residue.
run the codes to see if you left anything unplugged.

A 41 and 91 probable means you have a vacuum leak.

tripdrip, thanks for the info. today i cleaned the throttlebody and the intake manifold and replace all my vacuum lines. the mustang runs great now! runs better then before. it idles great too.
