ok time for an update! i took care of the grounds now have two extra, one from the battery to the radiator,and one from the firewall to the back of the head with some dremmel work, cause it didnt want to fit. the jeep is much smoother but still low idle! i still need to check the resistance but here is a pick after i left napa of where my idle is sitting!

 

much smoother though! oil pressure guage doesnt work, have determined its the cluster though

 

Amazing isn't it?

Too bad so many people don't believe it, huh?

What's next? Did you do #5 sensor ground test yet?

Did you voltmeter read that high before the refreshing/adding of grounds?

 

yes it is cruiser54, thanks for such a great write up,everyone should do this! im about to go do number five here in a min, just taking a quick break its hot outside! did i mention that when i took my coil apart there was a giant dead moth in it. wonder how that got there?

 

Be sure to wiggle the wires.

 

ok i just did #5 I get 0 ohms while wiggling the wires, nothing at all!!! so i take it my grounds are good. i'm still looking at a failing iac? i went through all my setting on my craftsman meter, even adjusted for the .3 its off and still have 0. i will be waiting!
Thanks
joe

 

Done 3 yet?

 

ok i know i already updated this, but yes i have done three, took the jeep out for a spin, throttle response feels great now, i can tell those grounds are doing something. retested the ohms and it looks like i have .1 resistance now. i will look again for more connectors/ relays to clean! but idle acts alot better now but still chills out at the pic above maybe alittle higher, but still drops to about there. almost there! i am looking for the 10 pin you talk about cruiser54.

 

.1 is GREAT!!

10 pin connector is forward of the air cleaner and behind the headlight on the driver side. Wouldn't cause this issue. Have you tried adjusting the TPS on the engine side now that the grounds are done properly?

 

i tested it a few minutes ago, i have 4.89 volts going through it, and its set to .82, i know its off just a tad and just wanted to update real quick.

 

I wonder if it's bad as in has a bad spot in it. Unplug the engine side of the TPS and see if it runs differently.

 

i just unplugged the tps 3 pin connector, at idle its about 800-850 rpms nicely kinda, soon as i put it in gear it goes to about 600, then i move the jeep and let it settle and it goes to about 490ish to about 500. it stays around that area even after the jeep is put into park maybe 550 ish. what does this tell us?

 

That's the same or different as before?

Trans plug still plugged in is fine.

Throttle body has been cleaned, right?

 

throttlebody has been cleaned, im really confused now, and as far as before i would start it it would drop to 750 stay there and drop again to about 500-550. so not the same as before but close.

 

just to make sure i tested again just under 1000rpm in park, 750 in drive, drive it and it drops to 550 and stay there no matter what. with tps connected

unplugged the tps 3 pin connector, at idle its about 800-850 rpms nicely kinda, soon as i put it in gear it goes to about 600, then i move the jeep and let it settle and it goes to about 490ish to about 500.
