I have been having problems with rough, uneven idle. Changed plugs etc resulting in no improvement. Started wiggling both of the 10 pin connector behind the intake manifold and one put the engine through medium to large missing, chugging, belching , farting etc until it pooped out. Put code reader on and it showed problems with Engine coolant temp, Air Charge temp, throttle valve position sensor and exhaust valve position sensor. Went to my schematics and found low and behold this connector was connected to all those sensors. Finally got the dang connector apart and found moderate coatings of pale white/tan/green greasy gunk on the pins and the female side as well. My questions are:
- Is this some sort of crap put their by Ford to protect against corrosion?
- Does it break down over time and cause problems?
- Whats the best way to clean this crap out well without harming the wires and connector?
Your help would be much appreciated Thanks, Bob
