Clutch install Now car runs lean/rich Help please

[Mooseman0]

Guys i just installed a mcleod rxt twin disk.

when putting back together I plugged the wrong sensor into the speedo sensor on the trans I Belive it was one of my rear o2 sensors which are deleted Thru the tune. when i relized my speedo was not working i swapped them and was good to go. Engine light was on for that about speedo sensor. It Also read like a low intake temp i belive i forget now i figured it just tripped something else like a chain reaction. And i read with speedo unooked it goes into a limp mode.

Any ways Now the car runs lean and rich. and pops a lot more than normal and jerks me around driving low throttle. Everything is plugged in . I drove the car for 55-60 Miles and no engine light yet to come on. I have vacation with the car in 3 weeks and really need to figure this out.
Any suggestions? tomrrow i am going to take the whole intake off and also make sure the maf is clean

Are you sure it's not clutch chatter?

 

[hotcobra03]

low intake temps?

check to see if tmap is plugged in all the way..its a mess with harness in that spot..

 

[Blueline]

I would re load your tune and see how it does. Also as mentioned you may see some clutch chatter until it breaks in.

 

[Mooseman0]

Reloaded tune. No luck. Its deffinitly not clutch chatter. Wideband reads 10.00 and pegs leans as well. And it drives jerkey. I'm going to clean the Maf now

 

[snakeraper11b]

Are you sure it's not clutch chatter?

That wouldn't cause it to jerk

 

[Mooseman0]

Its a jerk feeling from engine running lean and rich it seems

 

[Mooseman0]

Finally got the CEL back P0506 idle air control system rpm lower than expected

 

[Mooseman0]

cleaned the sensor real good with electrical cleaner and still no go. My buddy has 1 that he is going to let me use. It still runs mega rich and lean. I sit at red lights and exhaust smoke rolls up past me

 

[hotcobra03]

some reading from ford manual...it might be alot at once but it is always right..look it over slow..read pinpoint as if you pass..it will go thru all the things that cause code..step by step..

your starting point is KE2

P0506 - Idle Air Control System RPM lower than expected The PCM attempts to control engine speed during KOER self-test. The test fails when the desired rpm could not be reached or controlled during the self-test. IAC circuit shorted to PWR
VPWR to IAC solenoid open
IAC circuit open
Damaged IAC valve
Damaged PCM
Air inlet is plugged
The IAC solenoid resistance is from 6 to 13 ohms. Monitor IAC PID duty cycle and/or voltage.

Note: If stalling occurs place a shim under the hard stop screw to maintain idle conditions).

Key on, engine running.
Access IAC and RPM PIDS.
With engine at normal operating temperature, accessories OFF and at closed throttle, the IAC duty cycle must be between approximately 22 percent and 65 percent.
Slowly increase engine speed to 3000 rpm and return to closed throttle (Note: If closed throttle rpm is significantly higher than normal, ignore this step).

Ok guys So I went under the car, I or my buddy must have hooked the top Front above the extentions on the front o2 sensors wrong. I switched them vis versa and started the car let it idle good afr whole time and reved to about 3k and good afr didnt go lean or rich one time. I did not go for a ride yet but im 99.9% sure that was my problem Thank you everyone for your time and i learned a lesson not to switch those around on accident

 

[racebronco2]

I did the same thing before. Glad you figured it out.

 

[Mooseman0]

LOL FML what a fuc*king headache

LOL FML what a fuc*king headache

I figured out it out before i drove the car, once i started the car i knew i had them backwards.
