Quote: "I have a 1995 and a 2001 Buick Park Avenue. Both have very low miles for the year model. I have noticed that they both tend to wander quite a bit. I have had both aligned and new tires, front ends checked etc. I recently drove a 2003 and found that one as true as an arrow. Any ideas or comments? Did Buick have a handling/steering problem over this 5-6 year period? Thanks!"
That may be a reflection of what tires are fitted. The 2001 and 2005 are the same car. You could get an optional sport suspension on the Ultra, though.
My PA is a '97 Ultra with the standard suspension, and it tracks very well. Tires are 60-series Michelin Harmony radials, I think.

Quote: I am looking a '02 Ultra a Buick dealer. He is saying the ultra does not require premium fuel. Can anyone outhere give me the straight story is prem. fuel req. for the PA ultra??
The owner's manual for my '97 Ultra (same car, same engine) says regular can be used in an emergency, but premium is highly recommended. The reason is that the supercharger heats the air 100 degrees or so above ambient when you're on boost, so predetonation (knocking) is a real problem with low-octane gasoline if you floor it. To prevent knocking on boost when low-octane gas, the computer has to cut the spark timing way back when you step on it, so power and fuel efficiency will suffer significantly. AFAIK, the car will run fine on regular as long as you drive sedately and stay off boost, but I always run premium in mine (the price difference is only a few percent these days).

Your alignment may not be actually right in the middle of all the specs. If the rears are within specs but not ideal they can still cause some odd steering effects.
/What kind of tires. Really soft tires might cause more wander.

I have a 1999 Park Ave, doing about the same. At 50 mph, going up hill, tach is just below 1500, it acts like it should downshift, but i get the jerks, just like it would be cutting out. Once it down shifts its okay. Dealer has replaced Pressure selonoid valve on the tranny, but it is still not fixed. I noticed a reply to your email, did you try that and any luck.

Sounds like spark plug wires. You didn't say how many miles on the car. It's at least 6 years old, maybe 7, and the wires do fail slowly. It will act like various problems. It's a good time to replace both plugs and wires with original equipment wires. Don't try to new blue wires or the superdooper ones at the box parts stores. Get original equipment quality at GM or NAPA, e.g. The slight extra cost, if any, will pay off.
The problem is called spark scatter. The motor is under high load and the spark wires break down and let the spark jump to another wire or ground.

Al have you found out anything? Just happened to me in my 98PA. Happened when battery was reconnected. I have heard from 2 people in the business that the dash has to be opened so that the needle can be reached, and turned backwards to empty, not pushed over pin. OK. if thats the case, anyone know how to remove dash?

I just fixed this on my 99...Use a magnet, touch the dash right by the gauge and it will go right back into place.

The dash is a quick removal but that will not work because the glass is sealed. Take a magnet and touch the glass by the gauge and it will return to the proper location. I just did this on my 99 and is worked great, the gauge is accurate now. I did use a large magnet but saved $400 the dealer wanted.
