Thanks Besrk.

Tell me exactly what system you have.
On the ECM computer will be a label. It will have letteres and numbers on it.
These are the ECM # and the BCC-broadcast code.
Should be something like 1227747 ASDU.
I need those off the label.
You guys are really slow on information if you really want to fix this by the weekend!!

Nah - we are trying to fix it by next weekend. Have some transfer case leaking issue that we have to fix also. He is going to take it out Sat morning and see if the timing took care of some of it. It only was happening on some extreme angles so he going to go duplicate it. I was then going to get the number off the computer and check the voltages from that link you sent me.

I would recommend warming it up and performing the initial set up steps first.
This will ensure the min idle speed is properly set and that the IAC is actually working.

Under normal conditions...If the idle drops below about 450 rpm the IAC will shoot open to keep the motor from dieing.

The problem with that is no tach. I don't have one on my timing light and there isn't one in the Jeep yet. He is going to put a permanent one in but I don't know when that will happen. Any ideas? I don't really want to buy another tach because all the other TBI's that I work on have them already.

I'll pick a new tach up today or tomorrow, then we can install it sat morning before we do the rest of this.

Don't get too hung up on a specific rpm. An actual tach really isn't needed to get the min idle close.

I would much prefer you spend the $6 on cable parts and hook a laptop up to it to log some data.

The software has a built in dash board with a tach on it!!

I still need a tach by next weekend so the others who drive my jeep won't scatter my motor.

I'll also spend $6 on the cable parts to hook it up to my laptop.

If you have an older laptop with serial port it's a direct connect.
If not you will need a cheap usb to serial adapter cable.

Just follow the instructions in the thread.

I'll grab one at walmart or radio shack next time I go to town tomorrow.

The timing wasn't the problem. I know this weekend i'll get a diagnosis but my test drive today left my jeep with NO power from take off and it even died on me a couple times in my 1/2 mile test drive.

Aaron - if you get the parts for the cable and get that installed can I use it on mine too!? LOL

Either way it will be running for next weekend. I can swap parts off mine that I know are good sensors when we figure it out. The only I won't do is yank my distributor. I am thinking that we are going to spend a hole lot (yes I meant to spell it that way) of time diagnosing this. If you can reread the codes again as it may have set a different one than the VSS 24 code.

I forwarded my dad this thread and I think that he may be interested in getting into logging and burning chips. He is allot more computer literate than I am. I guess over 20 years working hardware for HP will do that to you!!

Bill - big thanks to you for sticking with us on this. Your forcing me to update my diagnostics skills!! I don't know if that is a good thing or bad thing - yet!! But thanks again - I don't know how many times people have problems and post them and then the thread dies. If you ever make it to Sprgfld - I got a frosty one for you.

Glad i'm able to help... I can't tell you how many people I see just throwing parts at their systems in frustration intead of just trying to learn something new!!
Then they give up and buy a carb!!

I have one more year here in Sicily before I return to US soil.

If you want to see some of my exploits just go to International off roading!

Thanks for the help Bill. If you do make it by Springfield I'll be the next round of cold frosty's. So cool pics on your site. I gotta say you have one of the cleanest scouts I've seen.

Well some of the problem Brad discovered was a bad ignitino module. Seemed to help a lot but there is still something that isn't right.

Did this change from last time?

Quote:
Bill - It isn't running in safe because after I changed the base timing and restarted it I watched the computer jumping the timing at idle. I didn't know that in safe mode it wouldn't change it tho. I just always recheck it to see if the computer is after I change it.
