checked the vacuum

 

It's accurate then....

 

It seems that way. So I'm thinking there definitely aren't any vacuum leaks with that much vacuum.

 

I like spraying with carb cleaner to find vacuum leaks.

 

I've sprayed around the injectors, the intake, the TB, taken all the vacuum lines off and plugged them with no change

 

Got a cap from the junkyard on Friday, but I have a test on Tuesday so I won't get around to cutting it and checking the indexing till Tuesday afternoon at the soonest.

 

Let us know.

 

Seems to have no stumble left after cutting one tab off and rotating it just a few more degrees, but the high idle is still there. One down, one to go.

 

Did you actually index the dizzy or just wing it?

 

Lined up the timing mark (that wasn't spun like the last one), too dead 1st cylinder, hole cut in cap, 1/8" past number 1, and snug it down gently

 

Get the gap below .020"

 

Got the edges lined up, so now onto some other things I'm noticing that I feel shouldn't be happening. The o2 heater voltage is rarely above 12 and never over 13. Also, sometimes the voltage the ecm is reading is 13.5, sometimes 14, sometimes 14.5. I haven't found a pattern yet with what causes the difference in voltages. I guess it's something I need to look into more and trace some wiring and such

 

Lately the Jeep won't stay in closed loop. There doesn't seem to be any rhyme or reason to if it stays in closed loop or not. Sometimes the o2 sensors will swing rich/lean and sometimes it barely moves at all. It always seems to follow rich and lean though. If I let off the gas it will drop voltage, and if I quickly stomp on the gas it will go up near 5v like it richens up. I'm not sure if the o2 sensor is bad and lethargic or if maybe something else is causing it. I have the old o2 sensor I took out of it still, so next time it's not raining and I'm not loaded up with tests I may swap it in and see how it acts.

 

O2 sensor heater working?

 

I haven't crawled under and checked with a multimeter since it's been very cold and very rainy here lately. The REM shows o2 heater voltage. It does fluctuate a good bit though on the REM.
