Please help! Idle issues now.

[ChrisAU]

Stock plugs is all you should ever run, CR43TS is factory.

Well brand new ones are in there. With process of elimination I'm hoping the new dizzy and fresh timing check/reset will fix it. If not, AC Delco plug wires. After that I'm stumped. Perhaps a new ignition coil? The one on it is riveted in, so I know its been on there for almost 180k.

Did you find the est wire to unhook when you go to set base timing again? and a coil either works our doesn't really, but if it is cracked or something then it could be acting up like a bad cap or something, just start with the dizzy then go from there. If you do get a new coil don't buy a MSD

Haven't looked yet, and yah I don't plan on getting any Might Soon Die stuff.

The biggest issue I've seen with the coils on the tbi's is "coil breakdown", you'll notice a whitish coloration on the outside housing where electricity has leaked thru to the horseshoe shaped bracket. That's usually a good sign that's it's on it's way out and needs to be changed soon before it leaves you stranded. Mine didn't start showing it till around 190k, but it could be showing earlier, most engine parts wear due to hours instead of mileage.

Thanks I'll check it to see if I that is happening.

When the coil leaks out power, it weakens it's spark discharge.

The new dizzy will be here Thursday...

Well I hope all of this resolves your problem.

Oh me to man. I'm hoping to take it on a hunting trip this weekend.

Well weather did not permit installing the new dizzy yesterday. Hopefully we'll be clear by Monday and I'll get a chance to do it then.
