Check the part #s of the MAF and ECU to be sure you are working with the correct parts
Clean the O2 sensor connectors and grounds
Inspect the Papa Indy 1 and 61 connectors
Did you remove and clean the transmission casting body connector underneath ?
All MAF and ECU connectors are okay
O2 sensors are okay but one of them has a lower reading at idle. I will change the positions to inspect an injector issue...
Papa Andy was okay too.
I release the gear box cover on the radio side... It was clean too. The main conector on the lower part from the gear box, could be on the my to do list, cause I cannot access easily to clean it. I will try it today.
I have notice a poor wiring on the knock sensor but I release the cable and try to start the engine and there was no issues or fouls codes at the OBD readings...
The power wiring is because there was a 150 ohms resistor...
Also it was only one orange-grey cable as showed on the picture.
Today I have checked the spring butterfly and it is okay. It can close the throttle butterfly easily (I contó close it more than the spring...) it estoy at the idle screw.
This is how it looks like. The spring is okay and also the idle screw...
Unless the throttle pedal has a return spring something has to drag the cable through the cable sleeve to return to the idle stop
Hard to tell if the updated stronger spiral spring is installed but a 2nd external straight spring can be add as a test to see if it give you the idle results
but you did say by twisting your hand you are already at the idle stop
Yes the IAC valve , but is recommended to put some heat on the inside of the TB in the IAC bolt tread area least they break off
Remember to leave the TPS alone for now
Electrically you can test the windings on the IAC step motor
This would be before risking bolt breakage
You may not see a open winding until it is warmed up or hit with a screwdriver handle on the side
You have 4 to the square power combinations or 16
but green to red is electrically equivalent in looking for a open regardless of polarity as red to green and so on
There is no problem with unscrewing the IAC I had removed easily a few moths ago.
I will compare the connectors with an other IAC that I bought and the patterns screw was different . May be I will adapt it to the throttle body in other to see what happens... let's see...
thanks

The IAC has around 50 ohms resistor between their pins so it's okay.
the thing is that the cone rail is out as you could see on the pictures below
The IAC I think it's okay but may this could be not okay and the dual rail are required to stop the cone spinning.
