i have had a bad starting and running problem with my car. While in the middle of doing my opti swap, i looked at my plug that goes into the top of the opti and it has blue corrosion in all the pins. Could this have been my problem? you think it can be cleaned and reused with some dialectric grease? Any help would be great. And if anyone knows how much a new one is, let me know. the car is a 95

 

It can cause all kinds of problems. Clean it up so no corrosion can srpread.
