ONLY USE AC DELCO. PERIOD. Others have tried third-party, only to have
problems. I used AC Delco plugs and wires, gapped to 0.5, no problems.

It's been almost a year (I have a '98). The fronts were easy, the back a
little trickier. But not too bad (compared to my '91 Grand Prix - a real
knuckle-buster).

Some other things to bear in mind:

a) 95 through 97 Auroras were recently recalled due to the nylon fuel
rail leaking. Check your fuel rail - if it's stainless, you're OK, if
it's nylon, GET IT TO A DEALER ASAP.

b) Might want to replace the Fuel Pressure Regulator (should be under
$50). The symptom of a bad FPR is long cranking before starts. It's a
very easy, two minute job - highly recommended you do this when changing
plugs and wires.

c) Have your refridgerant level checked. Symptom of this is driver's
side warm, passenger side cool (or vice versa). A/C compressor in this
car is a bit underpowered, so combine that plus low refridgerant =
grenaded AC compressor ($1200 repair).

d) check the oil level regularly. The dipstick sucks. Crankcase holds 7
1/2 quarts - don't put any more or less in there. A problem with many of
the earlier Northstar engines (like the Aurora) is the rear crankshaft
seals failing. Oil may seep out down the underside of the chassis, never
pooling under the car. This is an expensive ($1800+) repair as the
engine and tranny must be dropped and the engine split and re-sealed.

e) There is a known issue with the trannies in the '95's and most '96's.
Car won't shift above second. There's a shift solenoid which needs
replacement (there's a kit for $300-$350 plus labor or DIY).

I'm very well versed in the Aurora, and there are many other tidbits
(flashing headlihgts = too much grease on the multi-function turn stalk,
et. al.), so please feel free to post here if you have any further
questions.

Hope this helps.
