    '87 5th ave. No Spark to plugs, Yes Spark from coil.

    Hi folks. My '87 Fifth Avenue was running just great when I parked it a few days ago. Then the next day it would not start (turns over well, smells like gas). I started testing and found that there was no spark. BUT when I test for spark directly from the coil wire it does spark. I've got...

    Rear Door NOT Stuck!

    Hi Guys, Well, yesterday something went wrong with the left rear door on my '87 5th Avenue. It acts like the door can't be unlocked; it won't open from inside or out. The lock button moves up and down manually or with the power locks and it feels like it is connected inside, but... The door...

    Fuel pump leak?

    Hi Gang! I got Marty ('87 5th, stock) running really well now (I tried absolutely everything; finally drilling out, cleaning and adjusting mixture screws did the trick). But he's also developed a strong smell of gas while running. It does NOT seem to be coming from the carb. I can't see any...

    A/C Seals at Drier ('87 5th Ave.)

    Has anyone else had trouble getting the joint between the a/c lines and the drier/desicant jar to seal? I have a new drier, new lines and new seals (the original flat black metal gaskets) but I still have a "massive" leak at this junction. And it just doesn't look right. As I tighten the nut...

    87' 5th - Test 6280 Mixture Solenoid?

    Hi Guys, I am in the process of rebuilding the Holley 6280 carb on my '87 5th avenue. Before I put it all back together I would like to test the idle mixture solenoid. But how? Cant find anything about this. Can I just put 12V + and - to the terminals and see if it clicks? Which would be +...

    Removing Outside Vinyl Triangle, 87 5th Ave

    Hi Guys, I want to fix the broken opera lamp on my 87 5th Ave. I've seen the great detailed sticky thread, but it doesn't say how to separate the outside triangular vinyl panel on the rear door, behind which the opera lamp sits. Also it looks like the 88 (in the sticky) and 87 are different...

    WANTED Fifth Avenue RR Wheel Lip Trim, Frnt Bumper Filler

    Hi Folks, I need to replace the right rear wheel lip trim on my '87 Fifth Avenue. Also I would like to replace the front bumper filler. Hard to believe no one is making repros like they are for anything GM, but I guess all I can hope for is a good used. Thanks, -Mike Beda

    Cat Testing. Am I doing it wrong?

    Hi folks, I fairly recently got an '87 Fifth Avenue with about 115,000 miles on it. A variety of symptoms made me think that I had one or more clogged cats. Long story short, I dropped the exhaust system, and I "tested" the cats by taking my shop vac, setting it up to blow, and sticking the...

    Intermittent discharge

    My 87 fifth has an intermittent discharge on the ammeter. It can be slight or sometimes bad enough to set off the red discharge light. But of course it doesn’t happen when I’m able to measure anything. I have cleaned all the connections including the voltage regulator screws, didn’t help...

    Vacuum to fuel vapor can

    Hi folks, The biggest problem with Marty ('87 5th) is it idles really rough. Right now I'm checking for vacuum leaks. I've been disconnecting and plugging one line at a time hoping I'd find one that made the idle smooth out. The weird thing is that there are three hoses leading to the fuel...

    '87 Power Antenna Replacement?

    So after tinkering, and taking it apart a bit, I found out my power antenna is doubly dead: It's electrically 100% dead (and it's not the limit switch) AND the toothed nylon cord is broken. What's the easiest replacement for these? (I'm assuming original parts are gone or cost a good...

    '87 AC Cycle Time

    Thanks to Dr Lebaron and his vacuum hose info I now have WORKING AC! At least it seems to work- it's only been in the 70's so it's not like it's had a tough test. But I'm wondering if the compressor is cycling too much. I timed it and it seems to run about 14 seconds and then shut off for...
