Well, I figure you guys would be able to help a poor bastard like me out.

I've got a code #43 (Ignition coil) showing up and the damn thing runs fine except you can notice a small rough idle issue or misfire.

If it wasn't your Jeep then you'd never notice it.

Anyway, I took off the distributor cap sprayed the fuck out of it With WD40 and cleaned out any mud I saw. Still didn't help.

I was a jackass and sprayed the engine down without thinking, so I assume I just toasted the cap & rotor.

any thoughts?

Oh yea, :flipoff2:

Maybe this is a bit obvious, but have you checked the ignition coil?

Jeeez, you try to help a guy out... I'll try to be more sarcastic next time

Yea,

I tested the coil . kind of. I can't find my volt or ohm meters so I busted out the test light and found I'm at least getting current to it.

Here is the weird thing...

I unplugged the battery for 30sec to reset the computer, plugged it back in and the Check Engine light went away (obviously) but the idle returned to normal!

Now last night got damn cold and I walke outta the bar about 10pm started it up rough idle was back and the Check Engine light came back on.

So either my coil is slowly dying or the weather change is fuckin shit up!

Any input?

Justin,
Did you check the blinker fluid yet? That was what was wrong with mine. :flipoff2:

Use that hammer you just got.

try testing the map sensor. If it is jacked the motor won't run right. I think this has come up a couple of times now. Try the search function

Why? Is the problem too hard for you to figure out?!?

:flipoff2:

I had a similar problem over the summer. I checked everything I could - cap, rotor, plugs, wires. Then one night I opened the hood and didn't have my flashlight on and noticed that one of my wires was arcing to something. It had a small tear that I could barely notice unless I knew where to look. Not sure if you've checked your wires yet, but that may be the source of your problems.

Nope, just not worth my time :zzz: :zzz: :zzz:

btw, did you read Jeep Talk Mission Statement (http://www.pirate4x4.com/forum/showthread.php?s=&threadid=1223) number 81

This one sounds like a problem you learn to solve in High School auto shop :flipoff2:

Have you replaced the wires and cap and rotor yet?

Start simple reset the computer. then let us know.

I am new here so I probably shouldnt bust on anyone yet, but come on. If the code says ignition coil, don't clean the distributor cap. There are lots of things that can cause rough idle. If you don't want it to idle rough anymore, get a new ignition coil first, and then see whats up. Hint Hint, ignition coil isnt the distributor!!

Let's see... I'm getting THREE '43' codes... as in 12, 43, 43, 43, 55. It comes and goes... sometimes it goes a week after I do "something" to it before the 43 codes come back, other times it's a month or a day. I never know. After I reset the computer, the engine settles down again. Even if I don't reset the computer, half of the items I did below chased the 43 codes away for a few days or weeks before they came back. It is damned frustrating to think you finally found the problem only to have it come back a week or a month later!:mad:

So far... over the past year I have been getting the rough idle and the multiple 43 codes, I have:

Installed a new Accel coil, new Accel plug wires, distributor cap, rotor, Champion Truck spark plugs, cleaned the throttle body, cleaned the combustion chambers of carbon, cleaned the fuel injectors, cleaned every single electrical connection in the engine compartment, checked the wiring going to the injectors, listened to the injectors with a stethoscope, disconnected the battery to reset the computer, replaced both 02 sensors (at 101,000 miles some items needed replacing anyway), and set up a Voo Doo worship area in my garage and have rattled dried rooster feet and feathers at the engine after offering it a sacraficial bottle of Jamacan Rum. It hasn't done it in the past two weeks, I think it's thinking about what kind of Rum it wants next!:D

Incidentallyl... I posted this problem to several Jeep boards and a Jeep engineer contacted me out of professional curiosity. He only says the '43' code can be a lot of things, none that easily diagnosed... but that he and his colleagues can't figure out why my display is showing THREE '43' codes in a row!:confused:

Yeah that's right you shouldn't be busting chops here yet... a '43' code doesn't "say ignition coil".... it says:
"Peak primary circuit current not achieved with maximum dwell time. Misfire detected in one or more cylinders 1 thru 6. (4 and 6 cyls.)" That's a lot of fawking leeway in just what could be causing a 43 code!

Haha, thanks Jerry...

I THINK mine is just the coil, at least I hope. I found my volt meter and I am going to play with it tommorrow.

The rough idle is so slight and goes away after about 2min of driving. Infact on the trip up to TSF today it didn't even have any probs until I stalled it which tripped it back on.

I'll post as to what I find, so far if I reset the computer I still get a slight rough idle but the Engine light isn't there.

I'm wondering if the computer just doesn't compensate and thats why the rough idle only lasts for the first 2 min.....anyway, off to bed and then the auto parts store :)

Well I wish I could offer some help on this Code 43 thingy

But the only codes I have had so far are..

12, 24,55

Just so you know code 24 is the TPS I have replaced eleven of them so far... They dont like water....:)

A friend had similar problems..his started as a rough idle. after time the engine would die...his fix was the throttle position sensor....borrw a friends and see if it helps.....be careful of the torx the strip easy...new sensors come with 2 new torw screws....

If it runs rough just when you start it, it could be its cold and un happy. Check vacuum leaks everywhere. Clean the whole fuel system, and check injectors. Also if you made engine mods, could be the prob. When it starts the computer is on open and doesn't take any measurements from sensors, just runs how it was taught to. Then after it warms up a bit it goes to closed and takes measurements and adjust accordingly.
