I have a 91 Nissan Maxima. It runs well. Last week i took it to a mechanics to have the check-engine light check out. it turns out that one of the injectors was not working. he replaced it with an after market one. didn't turn out so well. so, i went to a junk yard to get
injectors from an old car. i brought them home and decided to clean them with a brake cleaner. since this type of spray drias almost instantly i decided to remove all of the injectors and clean them with the brake cleaner. now the car shakes and it seems as if it wants to turn off. can anyone tell me if by using this brake cleaner i might have damaged the injectors. or how can i resolve this problem
