need wiring diagram for a 1992 pontiac bonneville sse
#31
i have taken the dash out and cleaned the boards and stuff and all of the contacts but they still act jumpy the fluid is on level and the people at autozone wont pull the codes for me they can only do an obd 2 connector the temp guage sits around that position all the time and the boost guage is at -10 all the time unless im hard on the gas ....also how big of a difference is it between using regular unleaded (87) vs super (93) .....couldent i just use an octain booster

If you've got high mileage and probably some carbon buildup in there, your compression will already be a little higher than it used to be, so the tendency towards knocking on 87 octane will be a bit more. If you're happy with the way it performs on 87, fine, but I would try a tankful of premium and see if you notice a difference.
Figuring around 17 gallons for a complete fillup, and let'* say 20¢/gallon difference between 87 and 93, your premium surcharge is only $3.40 on top of the hideous amount you have to pay anyway for a fillup these days, so try the premium once.
