oh and...
(id have to get a shop to set the gap)
thats just not true..autolite douple plats (part app764 or similar?)(what i got from orielly's) come pre gapped to factory specs.If anything, its the old plug gaps that get messed up. DO NOT USE BOSCHE PLATINUM 4's!!! Chris hightower, or some other smart guy can explain why they don't work well... OOH yeah! reset the computer after tuneup and let it idle for like 10 minutes.
