Thread: My 1989 Jeep Cherokee idles rough?

Recently I had all 6 of my fuel injectors replaced (not by a certified mechanic) and now my idle is really rough where as it was not before.

The person that replaced the injectors swears there is no connection but I have to wonder, Could there be?

Could be one of them is defective..

However could be several things..

Could be that now the injectors are more efficient,, that something else is responsible..

Like,, try replacing spark plugs and wires..
Replace the PVC valve (a common culprit for rough idle)..
New air filter..
Not much $$ for all of this..

If none of that works,, I would have the guy check the injectors..
