Well I don't have the scan tool atm, I tried my voltmeter and I think it's a peice of junk and need to buy myself a good one.

But I have a mt2500 coming off eBay with all the gear I need to read my sensors. I got sick of trying to borrow my buddies, Hopefully this will Give me a direction.

Tonight I went through everything one last time and it all seemed good, pulled the Tb off and cleaning super good, then uncle bob stopped by...... Idle is better now also ajusted my tps to match

Once my brick gets in I'll see what it has to say but till then this will have to do

Oh I also forgot to add I think this new o2 sensor is bad.... It took napa 5 days to get it in and then when I went to
Pick it up the box looked rally'd needless to say I bought it and installed it no diff, but when I was testing it tonight I would only register .06 v and would not change at any rpm...... My new old Bosch atleast jumped in volts when the engine was revved. This one does nothing!!!!!

What you're doing now is temporary, right?

I'm giving you the proper way to do it further down the road after the MT2500 is hooked up and the true issue found.

Well I was bored tonight after work, I decided to do some tinkering on the jeep, here is a little video clip of it at idle. Since I have done all these tips on your list cruiser my jeep runs much better, also with the addition of the new motor but still haven't been able to shake this low idle problem before and after the new motor.
What is that ba ba ba ba poh ba ba poh ba poh exhaust sound? Is that how it is suppost to sound?
