I have a set of injectors that need to be installed. The cores must be returned and I have injuried myself and am unable to do. And my Help (ah, ah I'm his) got some new accounts and is to busy to do it by himself without keeping the truck out of service a few days. I need someone that can do it in a day so I can stay on the schedule. Working 6 days aweek only allows me 1 service day. Can anyone recommend a shop in the Central California area.
