I know now a days with coil packs and cam/crank sensors its rather difficult to set the timming any more on a car, but it can be done. Just rotate the cam/crank sensor and set your timming light for a few degrees from or away from the known timming mark or do the old fashion thing.
THe old fashion way I recall to set the timming is to set it by rotating the distributor while reading a vacuum meter and adjust it for the highest vacuum. Very simialr technique to adjusting the fuel mixture, then you lower the idle setting. If it wont crank, then you retard it a few degrees.
What would you do? My van lacks acceleration. You floor it and it slowly revs up for a gas engine. I see it has a block or thingie I must unplug to set it, but it doesnt say much more then that. I know a higher timming can cause pinging, but its got the computer on it and whats a few cents more of gas for better performance?
Also, any idea why cars with automatic trannys usually have the timming retarded a few degrees than the manual counter parts?
THanks.
