1992 suburban 454 7.4 has an issue with code 42 and stalling entering closed loop in idle. It has a bunch of new sensors and including new o2 sensor.
Ecm is 7060 with $d8 and refurbished already ( over 3 yrs old with previous owner)
What would keep a 1 wire o2 sensor pinned in voltage?
What would also cause code 42 directly when the truck fires up after cranking.
Truck has 330 on the dash
New (but cheap 6 month old) dizzy
new iac
new map
new cts
new o2 (bosh)
new ignition coil (not wires or clips between)
new intake manifold
new injectors
new egr
new wires (ebay)
new plugs
Im going to walk myself through the code 42 diagnostic tonight and report back. Im a little stumped (and stupid for the cheap parts)
Any advice is good advice. Thanks
