Can you isolate a faulty injector by cracking open the hard line at the injector, engine running? Much like removing a plug wire from a gasser. As each line is cracked, there should be a noticable affect on the idle quality. The one that has the least effect is the culprit. If all react the same the problem is elsewhere.

I did that today, they all seem to make it rock even worse that it already does.

I contacted my previous owner, turns out the motor hasnt had a valve adjustment in 25-30,000 miles.... thats probably why she rocks....

When I started reading the first post, I thought "Valve adjustment".

Do you remember this thread I posted a few months back? that engine almost jumped out of the engine bay it was rocking back and fourth so much. Adjusted the valves, and it was soooo smooth you couldn`t hardly tell it was running.

After doing that car, valve adjustments made a believer out of me.

We are advised to NOT judge ALL Muslims by the actions of a few lunatics, but we are encouraged to judge ALL gun owners by the actions of a few lunatics. Funny how that works
