I know this is not an Explorer question but thought with all of your knowledge some might have some ideas to help me with my other vehicle's problems as it has me pulling my hair out.
I have a 82 Mustang 5L ....(2BBL 4Spd)
On damp days after the choke comes off it won't idle, (starts fine) just sputters for a few seconds then dies. It runs fine going down the road but just press in the clutch and it dies. After about 15 minutes of driving the problem can just, on a dime, stop and the car runs great.
It sounds electrical so being a simplistic setup I just shot-gunned it; I changed the ignition module, coil, wires, cap. rotor and recently I hardwired the harness (I thought it might be a connector so I eliminated them..soldering the wires and using heat shrink and wire loom to make it look professional...the harness was no longer available anywhere)
....but the problem still exists.
This car is completely stock and in mint mechanical and body condition so things haven't been neglected.
Everything vacuum seems to be functioning correctly, the EGR valve has been replaced.
I dissassembled the carb, cleaned it all out but it was actually quite clean to begin with, nothing to report there.
I was thinking that there might be a possibility that the cat is causing too much backpressure and opening up the EGR but then why would it only happen on damp days? Plus there is plenty of power..but at times the cat smells hot...(it doesn't glow but you know it's hotter than it should be)
Also a vacuum problem also wouldn't present itself just on damp days.....
If anyone has any ideas please let me know as I am getting frustrated at this point.
Tonight I am going to insert a piece of sheet metal between the EGR and the intake to alleviate the possibility of being the EGR theory (disconnecting and plugging the vacuum line to the EGR did not help)
TIA,
Kurt
