Here's what I found:
1. Made the LED DLC tester. Gave me two errors. CODE 23 and 24. IAT Sensor Circuit and VSS circuit.
I know that I don't have the VSS mod in my instrument cluster. That shouldn't affect the hard starting should it?
IAT is the air temp sensor correct?, I've replaced it, but I have still have the old one so I tested both.
The old sensor I have read 4125 Ohm @ 49.1F
The new sensor that has been installed for a while reads 4390 Ohm @ 50.1F
Both seem to fluctuate resistance with temperature changes about the same.
If I have 4.7 V at the wires that feed it, I shouldn't have a short right?
2. I pulled and cleaned and tested in hot water my IAC valve.When its about 40F its open, when you heat it up in hot water it slowly shuts tight.
I also cleaned the throttle body out. Neither were very dirty.
I also pulled and cleaned my EGR valve at the same time.
I also used the jumper wire and set my timing to 5 DEG per my book, (some models say 8)
I'm letting the rig sit overnight now to see if the cleanings help at all, but I still have the CODE 23 and CODE 24, so I know the computer still thinks something is a foul with the IAT Sensor circuit, so I'm doubtful.
What or where would you direct me next?
Thanks so much, I'm already miles ahead thanks to you...
