I'm thankful that my '93 Caprice L03 doesn't have that Opti Spark distributor. Mine is one year before that thing.

Very helpful video. Thanks for sharing.

@Andyatallah It only works with the engine running. It works off the vacuum on the intake manifold.

the air intake flows through the distributor cap for filtration....

Dang I think the L03 in my Caprice had like all those issues they listed.

@LynolsOffice sure would help with that!

watch the (abits) vid they have on there it looks awsome!!!

Hey i have a 1995 buick lesabre i just bought and although it has a lot of miles on it i think it drives great. However there seems to be some stalling sometimes when i start the car. It runs perfectly fine but im worried if it could turn into something serious. What do you think it could be

at 29:06 that hose when my car is off i try to inhale ( absorb) air from it but its closed! dose it perform only when car is on?

take notes

Distributor electric spark DELCO always disrupts if entered the water! Did not find a suitable way to protect it from water that is very close to the bottom of this engine in the engin LT, what is the solution?

Hahaha road test, (yep it can be pushed). Hahaha. Due to ABITS one of the steps left out in the service manual was to; Have a wrecker on stand by. Lol

My 88 GMC Seirra 350 TBI 5spd has all those missing under load, wires next to metal brackets.....sucks up 87 gas like alcoholic, way better mileage on 93 :(

LO3 and LO5 did not use dual knocks. Those engines were used in Trucks and Camaro not Buick road master. Please fix title!

ABITS is unacceptable and should be trashed. Hahaha
