I have a 1993 7.3 non-turbo with about 130k miles. I am new to owning a diesel and am looking for a good mechanic in the Seattle area. Backyard mechanic or good repair shop that knows the 7.3 IDI, not just a code reader that charges to much and does nothing. I am not sure the right terms but I would like the IP timed and I have the flashing O/D light that comes and goes, and also may need new glow plugs. Maybe add a turbo too. I have been to two shops that "work on IDI". The Ford dealer said come back in 6 weeks we might be able to get you in, shop #2 said "never mess with the IP it is set at the factory". I live in South Seattle.
