      Hello all~
      I have a 1994 XL explorer, 2wd stick shift trans... 4.0L OHV engine. I just replaced all six of the fuel injectors exactly right, in my auto class, but now I have a few problems. It still runs a little bit rough, and over by the engine I hear a "tsst tsst tsst tsst" really fast paced and suttle, but it wasn't there before... and now at the tail pipe when it idles i hear "pop pop pop pop idle pop pop" faint popping in the exhaust, and it does this all the time.... I want to know if I may have uncovered a vacuum leak somewhere or if this is normal as the computer re learns the fact it has six new injectors.... any help would be greatly appreciated. Thanks!
