Running On 5 Cylinders!, AAARRRGGG... Options

[Allan]

I need some diagnostic help.

Car started missing at low rpm's only.

I thought that it could be a clogged idle jet or poor connection on one of my plug wires (it fits kinda loose).

Pulled all the idle jets and cleaned them up. Crimped the plug connection so it fits better.

No luck. Now it's even worse. Not a miss anymore but what feels like a dead cylinder at low rpm's.

It seems to clear up at higher rpm's but the motor just doesn't seem to pull as strong.

Ideas please... (IMG:style_emoticons/default/smile.gif)

Well, that was a big waste of time. (IMG:style_emoticons/default/mad.gif)

Re-cleaned the idle jet for that cylinder and I even tried Dan's suggestion and it didn't help.

How can I tell if it's the idle circuit and not just the jet?

If you pull out an idle jet, your idle should change. That is one way to know it's clear. Most of the time it isn't the jet itself, but the little passages to and from it. Test a barrel, pull one out and your idle should change. Stumble or pick up, either doesnt matter, but change. Drastic, you could take a little carb cleaner with one of those little red straws and hose it down with a little pressure.

My carbs are so crappy right now (Car not driven enough either), I swear every other time I light it off one of the friggen idles is gummed up. Driving it around usually clears them up. Sometimes I'll get anoyed, pull over and do the finger thingy. It works, car smooths right out. I am running Zeniths though, that might be different than webbers?
