Easy enough to test... with the engine warmed up and idling: 1: check ignition timing... it should be 10 deg BTDC (to the left of the "T" mark as you face the front of the engine) assuming you're not at high altitude; around 15 deg BTDC if you are at a higher altitude. 2: unplug the vac hose going to the distributor advancer mechanism. There should be no vacuum on the hose at idle if the hoses are properly connected at the throttle body and if your throttle plate is in the normal position for idle. Plug the hose and leave the distributor vacuum advancer port open to the atmosphere. Verify the timing is identical to what you saw in step #1. 3: Hook a fresh/clean hose to the advancer nipple. Apply vacuum to the hose while watching timing - use a hand vacuum pump (Mity Vac type of tool) or just suck on the hose. The timing should move to more advanced - i.e. even more to the left of the "T" - if the advancer is correct and installed to the distributor properly. The correct setup should have: * no vacuum at idle * vacuum at part-throttle "steady cruise" type of engine loads - i.e. low horsepower conditions or even revved up in neutral in the driveway. Timing should advance in this condition. * under boost pressure the distributor should see boost pressure and retard the timing. This happens only with higher throttle openings when the engine is under load - you can't get boost in the driveway... gotta be on the road accelerating or running up a hill. The only way I could see a "vacuum retard" function is if you have the vac hose hooked to the wrong port at the throttle body - i.e. to a port that sees manifold vacuum even at idle. You would have adjusted your distributor position to set timing to 10 deg with all this vacuum advance... under normal driving loads or even moderate throttle opening there is less manifold vacuum... ergo less vacuum at the advancer so the timing appears to retard as the throttle opens & RPMs build. A proper hose setup will have NO vacuum at the distributor when the engine is idling... removing the advancer hose should NOT alter timing nor change idle RPMs. miike c.

That's the one. I couldn't find it either. Good job. Ashybone.

Dz you will NOT regret buying this Starion, i know it's not an 89 but git sum bra ... chasin' that unicorn can get tiresome, ya herd ?
