Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

    one headlight not working

    I have friend with a later model (2007) Pontiac Grand Prix. Got a passenger side headlight out and he replaced the bulb to no avail...it was back together before I got to look at it so I didn't check voltage at the plug but he tried several bulbs and none worked so it's fairly safe to assume...

    anyone replace the strut mounts on a 96?

    I need to replace the strut mounts on my 96 Grand Prix SE and I've never worked on a car with a strut type suspension before....just shocks/coils on RWD cars. Is the bearing included with a strut mount? I'm told I need a "strut bearing plate" and figure that's what it is. I've also been...

    intake manifold gasket sets

    I have been confronted with two options at the local parts store - Gaskets with or without pushrod guides for my 3100. I don't want to take it apart before finding out which one I need; though they do have both in stock and the difference in price is negligible. I would just kind of like to...

    What plugs do you like?

    What brand spark plugs do you use? Any reason to go with anything but AC Delco platinums? I believe that's what was in there from factory. My car has recently been misfiring but throws no codes, my first stop is going to be the spark plugs.

    what's this connector?

    I noticed this and can't seem to figure out where it goes. Usually a car this old will have the wires bent or stretched into their permanent shape and you can find where a connector goes but that didn't work. It joins a wire loom down by the side of the brake booster. 2 wire connector, black...

    testing IAC?

    Has anyone here tested an IAC on these cars? Looking for specific voltage input at idle, off idle, etc My Grand Prix has decided to randomly rev up to like 2800-3k on startup sometimes. It normally revs up to 1300 or so to get the fuel atomized better when it's cold, then lowers down to...

    which is it?

    Which motor does my car have? LHO or LG8? General Motors engine designations (and the generations etc) confuse the bejesus out of me. Are the early and late 3100 SFI motors just different generations of the same basic motor? Which was the older 3.1 MPFI? Early 90s Luminas and such.

    EGR system

    I have what I believe to be an exhaust leak under the hood and it did not look to be coming from the manifolds, but near the EGR valve. Seafoam is great for finding the general area of exhaust leaks! What comprises the EGR system in these 3100 sfi cars? The only experience I have is with...

    where's my gas filter?

    Where is the fuel filter located on a 96 GP with the 3100? Any special tools required to change it out?

    stereo install help

    I've got a 96 SE with a stock-ish stereo that I'm swapping for a Sony xplod deck. I bought the wiring harness for my car but am left with two unused wires - blue w/ white stripe from the stereo - amp wire...AFAIK my car doesn't have one? at least this harness does not have a corresponding...

    battery replacement?

    I only took a cursory glance at where the battery is sitting in this (96 3100) car, but I seem to recall it being jammed under the windshield washer tank? Is that all I need to remove to replace the battery? Is 800-900 CCA in the right ballpark?

    wiring diagram for 96 SE?

    I'm looking for a wiring diagram for the stock cd deck on a 96 grand prix SE. Also, does anyone have a picture of theirs? I am trying to determine whether or not the deck in my car is stock or not...it says delco electronics but the backlight isn't the same color as the rest of the dash.

    cupholders 96 grand prix

    I got my new 96 GP SE yesterday, and it's a great little car for the money, but the cupholders......what the hell kind of cups did they think people used? Shot glasses? Is there anything that can be done about these horribly undersized cupholders or am I SOL?

    other fluids and capacities...lots of questions..

    I'm looking for the OEM recommendations for the various fluids for my 96 GP SE. Power steering fluid - What type? How much of it will I need if I'm flushing the bugger? Transmission fluid - What type? How much do these trannies hold? I don't even know what transmission this is, so if...

    hey

    New guy here. Taking "delivery" of a new-to-me 1996 Grand Prix SE coupe tomorrow or the next day. It's white. Mostly. Has a hood and fender from a red parts car, which will soon be painted to match body color. The car is going to be a daily driver for the next two years, no plans for...
