~need help important 93 bonneville SSEI~
ok after reading for awhile i might of found the reason why it is so slow on my boost gauge completely floored in drive for a long time the needle moves 1 notch past the 0 middle mark so does that mean i only get like 2-3 psi? is the needle susposed to go almost all the way down? this is very important to me this would deffentally be the problem if im right ok thanks.
I do this every time I acquire a new vehicle and its always a good starting point.
You can't always go by what the previous owner says they have done, or when.
Consider doing the following:
Oil Change (AC Delco filter)
Spark plugs (AC Delco)
Fuel filter
Air Filter
PCV
Plug Wires (Either Belkin available at NAPA or Dealer wires)
Change the Oil in the Super Charger (Get the SC oil from the dealer)
Use the proper Gas for this car 91 Octane or higher aleast put in $20
Start with what I listed above and go from there.
Also a good idea as mentioned earlier to get your hands on a scan tool and do some tests.
If you have no boost as you mentioned then something is wrong.
Good luck,
Dutch

Twice, you have been asked to put your request in the proper format - which you have ignored. Read this: http://www.bonnevilleclub.com/forum/...ic.php?t=73691 Then, post again properly. If this is as important as you say, it is important enough to have respect for the people from whom you are asking free advice to do it in a format consistent with the forum, and easily understood.

i think you may be under estimating the level of importance the octane has on your engine. you can drastically reduce kr by using a higher octane.
You need to be running 91 octane MINIMUM. 91/92 is preferred. It is REQUIRED in your engine. You are doing long-term damage, and actually NOT saving any money.
If you can't afford the premium fuel, you should sell the car.

It was bad BCS (boost control solenoid).
What do you mean you can't afford the higher octane gas?
Its typically 20 cents more per gallon than regular and 20 x 16 gallons is $3.20 for a tank full of the good stuff. Thats less than a pack of smokes.
Regular gas WILL cause you to get worse gas mileage thanks to your engine knocking, so in the long run it will actually cost you MORE.

I definatly agree with popatim. The cost of using premium fuel is not really that much more at all. I have TWO SSEi'* and use ONLY 93 octane. and I nail down AT LEAST 20 MPG with my '93 with a VERY VERY HEAVY foot..... my car hits the redline pretty much every time I accelarate.
I once tried using 87 and 89 octane in my '93 before I knew any better. I had massive noticable power loss and terrible mileage.
I would bet that the better fuel mileage and not to mention the huge smile on your face from the increased power is absolutly worth the price of premium.
I am not saying that your fuel is your ONLY problem here, but switching to premium will make a noticable improvement in both fuel mileage and power.
