Rick,
I wrote; thought of going to bio-diesel; if I had the $$$ to do so.. but it won't happen in NJ:
& I know some have done the propane conversions, but on 78-79 Broncos. But they have gotten state insp at a priv shop ($$$)
Anyway, off topic now Rick...
figuring I have some time now and this issue rally bugs me; I have a rant about NJ MVA and their contractors.
The NJ State Inspection Stations are manned by contractors w/state supervision & guidelines. They will not allow any conversions (exc for some who Do KNOW the laws and regs here, see below CARB EO). The 3rd set of items they ck for, after driver's license, updated reg. and insurance card, then all lights, is the OBDII check on OBD II vehicles such as my 96. If that OBDII test can't be done, then the vehicle is failed. I have seen a lot of 96 Broncos and F series fail bec. the OBD II test power ckt is dead due to a blown fuse. It shares same ckt w/cigar lighter and the wiring often chafes on the rear of the lighter's frame. It happened to me twice when I did my own cks with my scanner for a DTC. I finally found the short after a few hrs.
Anyway, it won't happen in NJ. btw, the newest addition to Insp cks failure is a tranny leak! These paid-off lawmakers are killing us little guys without the $$ to go for a new vehicle or lease or relatively time consuming/$$$ repair to avoid this circle **** on little maint issues.
EDIT; found da all-encompassing NJ law after a few hours and a call to a relative;
"39:3-77. Selling or using unapproved devices or equipment
No person shall have for sale, sell or offer for sale for use upon or as a part of the equipment of a motor vehicle any unapproved device or equipment of a type which is required to be approved by the commissioner.
No person shall have for sale, sell, offer for sale or use any device, part or accessory which changes or is intended to change the design or designed performance of any device or equipment required to be approved..."
NJ MVA thus sums this up in their site as:
"...To pass a safety inspection, vehicles are expected to be maintained according to the original manufacturer
