my Jeep is running rough! Check engine light is on.....

HEy people. My 1995 YJ 2.5l 4cyl is acting up. All of a sudden the idle dropped and it started to run real rough. Almost like it was missing. I tried to do the check engine light thing, but it blinked really funny. This is the order of blinks I got; 3,6,9,10. That's probably not right but does anyone have any ideas? I was a quart low on oil, and the Jeep only ran this way for a couple hundred yards. I also use synthetic oil, so I don't think it's an oil issue.[addsig]

Ok, I did it again. It looks like a 33 and a 57? Where is that list of codes?[addsig]

Hope that this helps! Tug
Start with the ignition off. Within five seconds, switch the key on,
off, on, off, on. (On is not start!)

The "check engine" light will flash. Count the flashes
Each code is a two digit code, so a (for example) 23 would be
FLASH FLASH---FLASH FLASH FLASH

It will never flash more than 9 times, watch for pauses!

55 is end of codes, 33 is normal if you dont have air conditioning.

Please note that some codes are NOT included below, this
is not a complete listing, but it IS very close to complete.

88 Start of test (This only appears on DRBII, it's not blinked out)
11 No ignition reference signal detected during cranking (bad hall
effect)
OR timing belt skipped one or more teeth; or intermittent
loss of either camshaft or crankshaft position sensor
12 Memory Standby power lost (battery cable disconnected)
13* No change in MAP from start to run
14* MAP sensor circuit open or shorted; voltage too low
15 No speed/distance sensor signal
16* Loss of battery voltage detected with engine running
17 Engine stays cold too long (bad thermostat)
21 Oxygen sensor signal out of range, possibly shorted
22* Coolant sensor signal out of range (or disconnected to set timing)
23 Intake air temperature signal out of range
24* Throttle position circuit out of range
25 Automatic Idle Speed (AIS) motor driver circuit shorted
or target idle not reached, vacuum leak found
26 Peak injector circuit voltage has not been reached
27 Logic module fuel circuit internal problem
OR
27 TBI injector does not respond properly to control signal
31 Evaporator Purge solenoid circuit open or shorted OR
Evaparator solenoid circuit
32 EGR system failure OR
Power loss lamp open or shorted
33 Air conditioning clutch relay circuit open or shorted
34 Speed control vacuum or vent solenoid circuits open or shorted
35 Cooling fan relay circuit open or shorted
36 Wastegate control circuit open or shorted
37 Shift indicator light failure, 5-speed (blown bulb) OR
Park/neutral switch failure
OR
37 Torque converter unlock circuit open or shorted, A-413 4-speed auto
41* Alternator field control circuit open or shorted
42 Automatic shutdown relay circuit open or shorted
42 Fuel pump relay control circuit
42 Fuel level unit - no change over miles
OR
42 Z1 voltage missing when autoshutdown circuit energized (whatever
that means)
43 Peak primary coil current not achieved with max dwell time
OR
43 Cylinder misfire
43 Problem in power module to logic module interface
44 No FJ2 voltage present at logic board
OR
44 Logic module self-diagnostics indicate problem
OR
44 Battery temperature out of range (see Note #1!)
45 Turbo boost limit exceeded (engine was shut down by logic module)
46* Battery voltage too high during charging or charging system
voltage too low
47 Battery voltage too low and alternator output too low
51 Oxygen sensor stuck at lean position
OR
51 Internal logic module fault ('84 turbo only)
52 Oxygen sensor stuck at rich position
OR
52 Internal logic module fault ('84 turbo only)
53 Logic module internal problem
54 No sync pickup signal during engine rotation (turbo only)
OR
54 Internal logic module fault ('84 turbo only)
55 End of codes
61 "baro" sensor open or shorted
62 EMR mileage cannot be stored in EEPROM
62 PCM failure SRI mile not stored
63 Controller cannot write to EEPROM
64 Catalytic converter efficiency failure
65 Power steering switch failure

Hmm...well it was probably 33 and 55. Which means your computer thinks that everything is normal. 33 is for air conditioning and will always trip if you don't have A/C. 55 is end of codes...means that its done throwing codes. Try unhooking your battery for about half an hour and then putting it back on. Drive the jeep around a bit and check it again for codes. If there is some bad stuff it will throw the codes.[addsig]

I'm starting to think that Tug might look like a bobble-head doll. Because he's got so much information up there![addsig]

Don't forget that doll will be calling out loud...
aaahhh db db bd bd bd who's in on this fine ride....
WHo's in for $5 for a try..

I hear $5,, who's gonna give me 10.
This auction has gusssssst began.


Seriously., if his head might bobble,
don't we ALL carry
auto deflation devices....

I wasn't born when they chanted:

I can not take the credit here, I just went back and read the past post and found where our good man Dingus had posted it some time back. It is a past post search thing. So USMPK9 where did you go to Auctioneer School Sir. Sound pretty good there. Thanks for the good words guys. Nice to have friends. Tug ;-) [addsig]

Tug,, Shhhh you're giving away the Best kept
secret here on Jeepz.com.....
"SEARCH"
The quickest way for the answer is simply search
from the menu on the right. Find several threads,
same topic, different authors, more info..

But if you tell everybody
how us old jeepers find our
wealth of wisdom, ,,,
will we still be wise? LMAO ;-)

Learned a long time ago it only nesscary to be look smart if you have research tools on hand. I make a living looking smart when I am as dumb as a coal bucket! lol I go out and apprase Antiques, Collectibles, Personal Property, Jewlery, Rolling Stock, Machinery, Tools large and small, and much more. Do I always know the value of the stuff I set the prices on? Not always but I know people and place to go to get the answers that make me look real smart at times. The credit is due to my friends, and sources. But like you said
