Wasps and bugs tend to find their way into the pickup of the fuel line. It doesn't seem to matter if the fuel cap was on or off, the little buggers find their way in. Rust is another common culprit.

OK I cleaned out the gas line and made sure everything was tight. It fired right up and ran great. Took it out to lunch and ran a few errands. Came back to the house and parked it. Went to take it out for one more errand a few hours later and started OK but as I started driving it the engine started to sputter and then quit. I limped my way back to the house but it was pretty dicey. For whatever reason it didnt want to idle and kept sputtering and even back fired a few times.
Also noticed this afternoon my oil light kept coming on when I would hit the gas. I checked and I have plenty of oil.
Any ideas?
If it makes you feel any better, you are having typical issues people see with old Jeeps that are starting to wake up and run in a second or third lifetime.
Because you had what looks a lot like a fuel line issue, I'd clean out the lines again to get that last little piece of crud out of things, Check the fuel filter again - it may have loaded up.
A backfire usually isn't a fuel issue - it says that a valve was open at the wrong time. I wonder if you could have a valve sticking open?
The oil light coming on is a new one to me. It may be totally unrelated to everything else. Any noises that would indicte low oil pressure at the time?
Great question.. I just installed a new muffler so I am still getting used to all of the noises. That being said, I dont think I heard anything unusual when I lifted the hood. What type of noise should I be listening for if it's a low oil pressure issue?
The first sign of low oil or low oil pressure in most engines is an increase in lifter noise - a lot of clattering. I've heard it said that hydraulic lifters have saved more engines than oil pressure gauges or oil lights.
The other noise I have heard when oil pressure gets very low is a solid thunk-thunk from down deep in the engine - a lot deeper toned "thunk" than ignition knock.
You drive an old Jeep as much by your senses as any gauges. You listen for strange new noises. You feel different vibrations. You smell fuel leaks or the sharp oil smell of gear lube vs. the normal fumes from the little oil leak around the valve lifter cover.
Crap - I just started it and am hearing a lot of noise. The dipstick says it's full of oil. Should I drain out the oil and start investigating? Any recommendations?
I hate to try to troubleshoot by email and remote control = I almost always never have all the information I would like.
A. If you have not changed the oil, by all means do so. Look at the oil you drain out. Is it all oil? Is there water in it? Does it have gas in it? Water and anti-freeze whip up into a frothy mess that mixes in the oil. Do you see any metal shavings in it? I'd change the filter as well.
B. Can you get an oil pressure gauge that you can connect into the plug where the oil sensor mounts? That will tell you if you have oil pressure or not. At idle even 10 PSI should be enough to prevent engine damage, but you should see 30 PSI for a good engine. Low pressure could be oil pump, or badly worn bearings internally.
This is starting to look like more than we can do as an email troubleshoot - you might need to get a mechanic to look it over. In an hour or so he can probably give you a good idea of what is going on in that engine,
