New Problem...rough idle

[akcskye]

Now that we have Cricket starting again, we have a new problem.

Rough idle.

It sounds like it is very under-revved...someone mentioned it sounds like it's running without a cylinder or 2.

I am not sure that I call the idle rough...it idles perfect, but at much less power than it had.

It did NOT have this problem prior to the failures before.

Spark plugs, plug wires, coil pack, fuel pump, and float have all been replaced, as well as PCV valve.

Oil has been completely changed as well.

So...where to look now?

Is there a possibility that there is still some "bad gas" in the tank (one of the suspects of it's initial failure), making it run like crap and it just needs to be driven now? It's been down since October 9, 07.

Any ideas greatly appreciated!

Kristi,
Have you cleaned the EGR valve , if it is stuck open it will idle very rough if not stall completely - you mentioned replacing a coil pack - which one , primary or secondary - you could have a tower or two that are not putting out any voltage .
