My CarFax has expired since I bought my GN, am now looking at a '91 300ZX twin turbo as a daily driver. If possible could someone run a CarFax for me? Thanks!! Jeff JN1CZ24H9MX500785

My PowerMaster has a slight leak where the pressure switch screws into the Master Cylinder. The result is that a little fluid/pressure is lost when the pedal is first pressed, resulting in a no-power brake situation for the first few seconds until the pressure builds up, despite the leak. I'd...

If I decide to keep my '87 GN (starting to look like I might) I will be needing a few items that I would prefer to buy used locally rather than mail order new stuff. Is there a good supplier who parts cars out, or has used parts in the area? I have found a couple over the years for my...

Some of you may already have seen this in the Cars For Sale section, but I thought I'd post it here in case some of you or your friends were interested. Thanks, Jeff http://www.turbobuick.com/forums/showthread.php?s=&threadid=50194

I have the wrong differential in my '87 GN, the speedo is WAY off, and it's not a posi. I was wondering if the rear end and rear suspension on the GN is the same as other G-body cars (Cutlass, Monte Carlo, etc). If not, what are the differences? Thanks, Jeff

Someone put a different rear-end in my '87 GN, likely a 2.73 low 3.00 ratio, so now my speedometer is about 15 mph slow. This seems to be messing up my shift points, and TC lockup. SO the question is where is the speedo gear located, and can I put the parts from the old tranny (which I think...

Now that I have my drivetrain squared away (til the mods start!) I want to figure out why the car sits low on the passenger side. It seems to be an inch or two lower, both front and back although the front seems a little worse. The car has been hit on the passenger rear quarter, and the frame...

Some of you may have seen my previous posts. I bought an '87 GN for what I thought was cheap and found that it had a replacement 2004R from a station wagon or something else lame (along with all the OTHER problems the car had, such as being a stolen car). ANYWAY, I found a 30K mile trans from...

I have been fighting some really weird problems with my '87 since I got it back a few weeks ago. The main problem was that it failed the emissions test which is part of the state inspection, so I couldn't legally drive it...that sux. Today I passed it with flying colors, a huge difference...

This week I noticed a problem with my ECM when the car got warmed up. It would intermittently go to Open Loop mode and all the codes got completely screwed up, the tool said the tranny was in D/R when it was really in P/N, the RPMs were WAY off, speed was way off, the car was running like crap...

I'm about to put a couple gallons of Xylene in the old '87 to try to clean the fuel injectors. It failed the emissions test this week, I am wondering if running Xylene would help or hurt emissions (HC, CO2, NOX). Thanks, Jeff

I have been attempting to adjust my IAC and TPS today using an Actron ScanTool (it's what was available to me today). I had spent 30-60 minutes adjusting, shutting the car off, readjusting, restarting, etc. Towards the end of my adjustment I started getting occasional erratic numbers, things...

After my '87 failed the Texas emissions test today I started giving it the once over...found some bad vacuum lines which I replaced (anyone with a complete vacuum diagram please let me know where to find it!). Next, I started the car, it seemed to run a little better at first, but still smells...

I checked gnttype.org, didn't see it there, did I miss it? I just failed the emissions test here in Texas, and noticed that my vacuum lines are in pretty bad shape. I need to replace pretty much all of them, and I want to make sure they are going to the right places while I'm at it...

I just removed the IC to clean it per the Spring Cleaning tips on gnttype.org. I noticed that the outlet side (to the TB) had quite a bit of what appears to be an oil/gas mixture puddling around the IC hose and coating the outlet neck. There is nothing like this on the inlet side, and the...

Don't know if anyone was following my story, or if anyone even cares...but.... I bought an '87 GN which turned out to have been reVINed as an '85 Regal. I turned it in to the cops, and waited for several weeks. About two weeks ago, there was a hearing, and the insurance company relinquished...

Long story short...I needed some good rubber to get my theft-recovery '87 GN to the TXDOT for a new VIN tag. I had a couple 15X8 Corvette rallies that I had painted black with good 235-60-15 tires, so I bolted them on. WOW...they really fill the wheel well nicely! I don't know if it's the...

Since I got my '87 it has never wanted to shift from 1-2 on heavy throttle. I have posted here and gotten a couple different ideas, TV cable and the suggestion that it's just not calibrated right, since it's not a BRF. Well, while perusing some of the other messages here I noticed that these...

Tranny maintenance...things to check while pan is off? I'll be dropping the pan on my '87 GN 2004R next week to change fluid and check things out. Are there some things I can check or replace while I'm in there? I'm planning to install a drain plug, though, in case I need to drop the pan a...

Getting ready to do a bit of upgrade on my 2004R, can you tell me what this "bottom feeder" is, how it's beneficial, and where to get it? Thanks! Jeff
