• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

    Gotta brag to someone...

    Most of the world wouldn't really care. But I just drove my '04 GP to Michigan and back, and got some fantastic "performance" numbers: Tank 1: 34 MPG Tank 2: 36 MPG Tank 3: 30 MPG (included local driving near my vacation spot) Tank 4: 33 MPG Tank 5: 32 MPG So - I drove about 2,100 miles on 5...

    Making the horns more audible to others

    '04 GP I've noticed that the horns are pretty much pointed into the engine compartment. This is great for passing inspection, but other cars usually cannot hear me when they are changing lanes without looking (or any of the multitudinous other ways people drive like idiots). Has anyone...

    Changing subframe bushings - a nut broke free

    I have an '04 NA GP, 267k miles. I was going to change the subframe bushings today, but on the driver's side (rear bushing) it appears that the nut broke free. I think there is supposed to be some kinda tab that keeps the nut from spinning. Now the bolt (and nut) just spins. There is a little...

    Sick of honking at myself! Re-aim the horns?

    I have a 2004GP. I've noticed that the horns are pointed much more at me, than they are at surrounding traffic. While this is great for passing inspection and "thinking" I'm alerting someone to a problem, fact is that other drivers can barely here me. Anyone tried re-directing the horns? -Bob C.

    INFORMATION How to remove "sticky weight" residue from wheels?

    Does anyone have a good way to remove the residue from "sticky weights" from wheels? (If there is an acid of some kind, hopefully one that doesn't damage the finish on the wheels) I've tried brake cleaner, adhesive remover, etc., all with less success than I'd like. I know there are stronger...

    Question about shifting tables (HP Tuners) on cruise control

    I have an '04 GP with no supercharger or traction control. I've modified the TCC and 4 ->3 downshift tables, and I like the improvements a lot. However, when using cruise control it feels like it ignores these changes. Could the computer be looking at the "hi performance" table when I'm on...

    Anyone added fuel capacity for extra range?

    My daily commute is 145 miles, if I don't have to run errands or anything. So I am at a gas station too often. Anyone added a fuel cell, or come up with other creative ways to increase fuel capacity?

    How to measure correct ride height?

    2004 GT. I just installed Quick-struts all the way around. Obviously it's going to sit higher than it used to... but it looks much too high to me, especially in the front. Oh yeah, and MPG has dropped from about 27.3 to 25.5. What is the measurement for correct ride height on these cars? -BC

    Got a jump start... now my gauges die and my radio shuts off and...

    This morning I had to call AAA for a jump start. Without giving too many details, the jump start was very poorly done and I think it fried a computer or ??? 2004 GP GT, basically all stock. Here are my symptoms: - Everything works fine for about the first minute after the engine is running -...

    Dumb n00b question... shift kits vs. reprogramming

    I see that it is a popular mod to put the trans-go shift kits. I totally understand the reasoning here, and will be doing this soon myself. However, I thought that the computer also had settings for the shift time.... and that if you changed these settings in software, the computer would just...

    Is there a good bluetooth OBD II scanner for iPhone?

    As in the title... A friend of mine showed me an Android app (I forget the name) which looked like a fantastic OBDII reader. He had some pretty neat gauge capability. Apparently the setup he had is not available for iPhone. Is there an "accepted" nice OBDII reader for iPhones? -Bob C.

    Can I use a 78DT Battery?

    In my '04 GT, I would like to replace the group 34 battery with a group 78DT that I have. Any reason that won't work? -Bob C. p.s. In anticipation of some questions.... 1) My existing 34 is a 5-year battery, and it's 6 years old 2) I have a barely-ever-used 78DT from another car that got...

    IGN Power stopped working... Even though I replaced the fuse

    2004 Grand Prix. I had the radio out, and a bare spot touched a metal screw. I blew the fuse for the 'ign' circuit (so the radio wouldn't come on). I replaced the fuse, but the radio still won't come on. I poked through the harness with a test light, and the radio will get constant 12V but...

    Totaled my '04 - gonna part out. What should I save?

    2004 GP/GT, gray/gray. A few weeks ago, I rearended another car. It was an awkward hit., so it damaged my hood, radiator, etc. However, basically everything from the engine rearward is good. But the damage was enough for the insurance company to "total" the car. What items are hard to get for...

    How to post a part-out?

    Forum rules say that each part for sale needs a price and picture. However, since my car ('04 GP) was declared "totaled" (but has a TON of good parts), I wanted to let the forum know that I'm parting it out and to ask me for whatever they needed. Obviously I'm not going to post a pic/price for...
