[QUOTE="EddieS'04, post: 982559, member: 61136"] Just something to throw out there. You say in the case of dampness mostly. I would unplug the ecu on the fire wall. Look for corrosion. Use a crc contact cleaner. Re install with di-electric grease. Do the same for all major harness connections on the motor. Unplug and replug the fuses and relays, in the under hood power box. The ones related to the motor. ECU, fuel pump, etc. That will wipe any corrosion on them. I was thinking plug wires being damp and causing problems. Did you use a good qaulity wire? There are cheapos out there. I have had that problem with, until they dried out. I wont buy the bottom line store brand plug wires. Make shure all plug wires are seated good. Check the master plug to the coil also. Another thing is dont use engine degreasers or foaming cleaners or steam cleaners on modern motors. They are corrosive, and get into contacts. Dont use high pressure sprays or motor cleaners at car washes. I use the low pressure spot free rinse is all. I never hold the spray in one place around conectors. This is just ideas only. Since you say it misses and runs bad when damp. [/QUOTE]
