2000 Ford Windstar, 3.8L V6 engine, automatic transmission, 166,000 km, recently purchased, was brought to me for some torubleshooting and minor repairs
- Occasional hesitation
- Check Engine Light on, code was "cylinder 5 misfire"
Troubleshooting done so far:
disassembled wiper blade cowl and removed wiper assembly to gain access
removed spark plug cables (resistance test not done yet)
removed spark plugs: #5 looks new except for some brownish colour, the other 5 are pink, all gaps are on the high side (high 50's, should be mid-50's)
- What causes pink colours on spark plugs?
