i have a customer that has one - its a 85 by the vin, but says 86 on the emission sticker - i noticed it because the vaccum diagram showed an advance, then confermed when i did a tune up - only a power and tack lead out of the dizzy, with an advance - its the only one ive seen in person.


and a 88 burban with a tbi 350 - ill get you an ecm diagram - dose the map sensor have vaccum ? no leaks to it ? 5 volt, ground and signal ? ill get a few pics
Odd--the first TBI's we saw in non comercial vehicles was in 87 but we never saw the comercail stuff.
