    87 GN w/ astroroof near Indy for sale

    I regret that it is time for me to sell my Grand National. It is too good to be used for a daily driving as I have a Suburban 2500 w/ 8.1 engine and it sucks in gas. I need to sell my GN and buy another car with good MPG, so I can start driving it and put my Suburban aside for towing only. OK...

    Which auto store to purchase alternator?

    My 87 GN needs to replace a weak alternator. It was tested and discovered that it is only feeding 76amps. It should be around 120 or 125amps for GN cars. Is it the reason why my car wasn't going quick enough because fuel pump wasn't functioning 100 percent? Anyway, Auto Zone has an OEM...

    Installed adj regulator, cold/warm different pressure reading??

    Billet adj fuel pressure regulator installed in my 87 GN. Set at 42 1/2 psi with vacuum line off when first started the engine. After a little while of driving, I re-checked the fuel gauge and discovered that it has dropped few psi's. So I re-adjusted it to 42 1/2 psi again when engine is warmed...

    Hi. I just woke up my 1987 GN with 92k miles today and drove it. The last time it was on the road was last October. After about 20 miles, the check engine came on. I ran the code reader and it came out as "45". I checked gnttype on the web site, but they no longer there?? When I opened the hood...

    Since winter is approaching very quickly and we are putting our two daily driven vehicles in our two car garage (wish I would have a 3 car garage!) Instead of storing my 87 GN at the public storage and paying $100 a month. Is it ok and safe to store my GN in the enclosed trailer outside next to...

    New wastegate solenoid, underboosted??

    Joe Lubrant burned a new 93 chip (set at 18 psi boost while it has non-adjustable rod) and it was overboosted at 20-21 psi with a lot of hesitation like it was coughing. Took it out and he burned another one and it improved. It still spiked to 20 psi but returned to 18 psi and stayed there...

    Got beaten by a GTP!?

    My 90k miles '87 GN with stock engine, trans. and rear end (open, yuck). The only modifications I made on this car were 160 thermostat, cold induction system from BuickGN.com, and a 9" cone K&N filter. It runs very well and it gets about 16 psi boost as indicated on the factory LED boost gauge...
