I didnt check both. I think only one ground grounds at the battery. all 4 wires are the same size. one wrie is fused relay. one is sensor ground. ground then sensor signal. thats what the pdf said

did you replace both O2 sensors (you said you replaced the O2 twice, not sure if that meant both or the same one twice).

replaced the same one i think 3 times

use one of the ones you took out and replace the second one - maybe that's the one with the issue and you were replacing the one that was fine - just a thought

I'll see if one will fit. I know there are two different part numbers. its cooling down right now. i'll check in a bit

[chrisjsmith4]

It won't work. The plugs are different. i'll have to buy another one which sucks.But I did test the ground which had tone so thats not it.

Took the Jeep back to the evil man and ran some more tests. He ran me through the tests on checking why the heater circuit code is tripped. Everything checks out fine so he recommends I get the PCM flashed or getting a new one. New ones are 300 and to flash is 80. I think I'll go with the flash. I'll have the fuel controller in this weekend and i'll take pics . Finally have time to get some stuff done.

Try eBay for the ECU; I found one for my Jeep for $50 or so...

unless there's a newer firmware revision that addresses that bug (assuming it is a bug) flashing won't change anything

I'm thinking maybe I messed something up when i installed the turbo and didn't have an 02 sensor in.

worst that can happen is that it would store a code and that can be reset with the scanner by the evil man

[chrisjsmith4]

I'll check ebay for one first then.

A couple pics of the intercooler set up

A couple pics of the intercooler set up

there's no airflow in that spot, so once the i/c gets hot (which is about 15 seconds under boost) it won't cool anything - maybe have a grill on top of the hood with a fan on top of the intercooler blowing thru downwards.

not trying to put down what you did but the way it supposed to work is by having cooler air thru the fins to remove the heat buildup that was transferred from the intake air into the intercooler tubes - the way you have it won't cool at all, you can test that by having a temp sensor ahead and after the intercooler. Subaru (if i remember that's where you got it from) has an air ram vent on the hood pushing air thru the i/cooler.

[chrisjsmith4]

Ya. I'm gonna find a fan to put on it or just do an water to air intercooler. Its just acting like a makesift radiator right now. I noticed a difference right off the bat with how it ran. Its just temp.

BTW. got the fuel controller hooked up just now. Gonna start it here in a few minutes.
