[QUOTE="EddieS'04, post: 991660, member: 61136"] Never wash a modern ECU controled EFI motor with cleaners or water hoses or steam clean. To many critical low voltage sensors and connections. That may get contaminated or wet. I wont use wd-40 on connectors nowdays either. I will use crc electrical cleaner or other brands that are safe for plastics and rubber. To clean electrical connections. It is usaualy alcohol based. Evaporats fast and no residue. You may have shorted some things. Or you still have wet connections that wernt sealed well. Or even the wd-40 causing intermitent connection problems. If it was running ok before. It may need to dry out good or do some connection cleaning. [/QUOTE]
