When something like this happens to me I take it all apart again until I find what I did'nt do right.
It has to be something you did or it is a coincidence that something else decided to go bad because it doesn't like you.
An air leak is suspect-unmeasured air -, that is, air coming into the intake bypassing the AFM,
which will cause the computer to increase injection time at idle-the exhaust will be black if it's real bad. Too rich at idle will be a very rough running engine.

Hoping that you all can come to my rescue... yet again....
I just completed pulling the entire air intake / fuel delivery assembly off
of the engine, cleaning it up a bit, replacing the fuel lines, and spraying
some cleaner into the throttle.
I replaced the throttle gasket, and the head-to-air gaskets... fastened the
acce;erator cable, etc., and put the whole mess back together. Upon first
start, as I expected, the car did not really want to do much. I pumped it a
bit and she started up and continued to run in low idle (1000 rpm).
The problem is that the engine now runs REALLY ROUGH at 1000 rpm... so much
so that I cannot bear to leave it idle there, I pull the throttle cable so
it is idling faster, and all seems A-OK... runs smooth, engine is not
jumping around in the mounts anymore.
But as soon as I let it go, and it idles down at 1000.... nasty rough idle
again.. seems like it is missing or something, engine is trying to jump
out... ... timing???
My question is, since I really did not take anything out of adjustment,
(knowingly) how can it now be so out of tune?? Does the engine require more
time to get all the air out of the new lines?? Is there any component on
this assembely that I may have bumped that could cause this (Would the
throttle switch show this symptom if misaligned??).
Any help will be greatly appreciated. Thanks!!
