CarFax shows first registration on 3/27/98 at 496 miles.


Where was it for six months and 500 miles? Sales Rep use?


Not that it matters. Just blathering.

Probably. I've heard about salesmen, or reps who are given the use of a new vehicle to drive for awhile. Kind of like a bonus for them. They'll use a dealer's plate, so it won't need to be registered.

This thing came with an aftermarket locking gas cap. I found I could turn the key to uinlock it and remove the key leaving it unlocked (which is what I wanted). But, I put a tag on the key and tossed it in the fold down armrest.

Went to gas up a couple of weeks ago and the cap wouldn't open ... locked. Took me a minute to remember the key was stored there. But for some reason it would no longer stay unlocked. Maybe it wasn't supposed to ?

Found a 'genuine GM' item with a tether ring on 'Zon and ordered it. Fits fine, but I'm hoping it's the right one and I won't have venting issues. GT 225, 15763225

Replaced the 4x4 switch and got light again. Did it the quick way and popped it out with a flat head. No damage to the bezel but cracked a tab on the old switch. Never got the service 4x4 code read but if it comes back after the swap I'll go to a shop and see.

Love those old switches!! I've got a 2012 Yukon and my switches are CRAP compared to those.

I refreshed a 4L80e for my younger brother back in the Spring. He's doing a LQ4 swap into his 90 C1500 RCSB (that counts, right?) . Yesterday he finally took it out on his maiden voyage... said it shifts good!

I helped him on general LS swap information and the transmission. He did the heavy work and the wiring. Kinda proud of him. My Dad was never a car or truck guy. We learned by reading, watching videos and of course, getting our hands dirty and mistakes too. We're just DIYers.

Changed the oil on Betty today. On Saturday, in preperation I put some seafoam in the tank and crankcase and went out for my Italian tune up. I floor her in my usual 1/4 mile stretch and as she hits about 90 start getting a vibration. Check engine light starts blinking and I back off throttle. Vibration stops and light stays solid. By the time I get to get it scanned on Sunday it had gone out but a p0300 stored. No other issues starting or driving before or since. If it stays out until next oil change I'll see what the WOT does again.

Could be your cats causing the issue.

That's what happened with my 05 Express van. I got so many random misfires(P0300)that it eventually clogged one of my converters. Iirc there's 2 converters---so I just hollowed out the clogged one. No more random misfires.
