Jeep running horrible?Could it be weather?

I haven't driven my jeep in about a month.
I put some new plugs in yesterday because I found out my old ones were fouled.
Put everything back on..started up very powerful and had an awesome idle.
Well I want to drive today and its barely running.
It's stuttering very badly and wants to die.
It picks up occasionaly..but its running very very bad.
The problem is, there is a guy who wants to look at my jeep and possibly buy it.
I listed it on jeepclassifieds a long time ago, and forgot to take it off after it caught on fire.
I told him it caught on fire etc..and he still insist of checking it out, as he says he is pretty interested.
I took the hood off to strip off the old paint and get the rust underneath.
Well I haven't put the hood back on and it dropped from about 60 degrees yesterday to a 24F, with a 14 degree windshield.Boy it is cold!
I'm wondering if the combined cold temperature and no hood could cause the problem?
I'm hoping the jeep still runs well tomorrow.
I let it warm up for a few minutes,and she still is acting bad.

Thanks for any info

“It's stuttering very badly and wants to die.”
Things to look at:

Moisture inside the distributor? Wipe the cap dry, check the contacts, rotor, wires all the way in.
What condition are your plug wires in? Wipe them off and see if that improves it. If wiping them helps spray them with WD-40 before the guy gets there.

Fuel system, steady fuel flow? spraying gas, not dripping gas? Water in the gas?
I'm guessing you have a good air cleaner.

Cold weather isn't normally a problem. 24° is pretty mild here.

Stuttering is a very broad descriptive term. Sorry, I can't help you more[img]/wwwthreads_images/icons/frown.gif[/img]

Re: Jeep running horrible?Could it be weather?

new air cleaner, hei distributor, 4 barrell holley
Its just a lose of power.
I'll hit the gas and it takes a good time to respond, and when it does respond its severly underpowered.
Occasionaly it will go up to speed/power,but usually drops off again within a second.

Most of my wires are new, I might buy new ones if it keeps acting up.

Re: Jeep running horrible?Could it be weather?

Did you replace the fuel lines too?

Re: Jeep running horrible?Could it be weather?

How long did you drive it? Mine runs like crap until it warms up. Even when it was in the low 40's in the fall (it's in storage waiting for "salt season" to end) I had issues. After a few miles it ran pretty well. Your lack of hood could be causing the engine bay to never warm up. If you can, put the hood on and drive it for at least 10 minutes.(Or just light it on fire again and drive for a while [img]/wwwthreads_images/icons/wink.gif[/img] I couldn't resist) If that doesn't work try some of the above mentioned ideas.
Good luck.

Re: Jeep running horrible?Could it be weather?

I put the choke in different positions(manual choke) so that it will keep running.
It runs better at full throttle with the choke open, but when I'm slowing down,a fully open choke will sometimes kill it.
Lol about lighting it on fire

I didn't reaplace all the fuel lines.I replaced everything in the rear, but not the steel lines that go from the pump to my tank.
I've put gas cleaner and all that stuff in

Re: Jeep running horrible?Could it be weather?

Kind of sounds like it running lean. Either from a hole in a fuel line between the tank and pump or from a vacuum leak. Since it accelerates ok, I would check for leaking vacuum hoses or gaskets between the carb and head.

Re: Jeep running horrible?Could it be weather?

More info.- good deal. I agree with WILL sounds like it's running lean.
In addition to WILL's suggestions, I'd check the fuel filter, too.
"Plenty of gas" isn't a full tank. A partial tank of fuel during lay-ups allows a lot of condensation to accumulate. The new reformulated gas goes bad quickly, too—I don't know if you use it in your area. Even Sta-Bil doesn't always work during lay-ups with reformulated gas.
I'd drain the fuel bowls and check for water. Additionally drain fuel from the tank's fuel line into a glass container and check it for water.
If it is a lean burn problem be very aware of your engine temp. and any strange cylinder noises. Great harm can be done running an engine lean, so be careful.
TR has forgotten more about Holley's than I'll ever know. Maybe he could help, send him an e-mail.
