just got my 84 and just read whole post my timing was off but putting in new timing chain this weekend what did you find was the problem with idle thanks for all the info and picts

The poor idle seemed to be caused by a bad intake manifold seal. I tightened up the bolts that mount the upper plenum to the intake manifold. The loose bolts caused a vacuum leak and poor idle. The idle is just a shade high now and I believe that is a result of my timing. I will dial it back tomorrow from 10 degrees to 8 degrees and see if it lowers the idle a hundred rpm or so.

on the front panel of mine it says 6 degrees before for correct timing the problem I had with mine is it would run fine but at like 13 degrees btdc and just got thru pulling heater core and man it is a pain basically have to pull whole side out ducts ecm body brace but I got it out waiting on new one

Thinking about changing the color from black to light bronze metallic. Any thoughts on this?

Your light bronze looked great.

I had a gold '87 and it kind of reminds me of that. I liked it too.

Although I like the light bronze better than the black, I doubt if I would change it. Changing colors takes a lot of prep time and disassembly to do a good job and make sure all the black is covered.

I agree that it may be a difficult job to do to change the color. When I paint the car I am going to tear it down completely and paint it properly. We'll see what time brings. I'm not made my mind up entirely.

First of the 4+3 parts are on their way...

Went out to the garage today and reset the timing and readjusted the idle. Now we are rock solid at a 700rpm normal operating temp idle. So far I'm happy with the results but since there's a lot of snow on the ground I can't drive the car to confirm everything until the snow clears out. Only a couple more months until spring.

The best is just after 1/2" of snow -- trying to get up a 15 dreg. over pass

3:AM -- I had to back up a 1/4 mile to a side street --- and went back home

Truly awesome to see this '84 come back from the brink of parts car hell. Kudos on this save...love seeing where you are taking it.

Thought the Jeep would be good in the snow... Have you guys gotten hammered with snow this year?? We certainly have. Its been awful.

mazdaverx7

Lee, I appreciate the kind comments and I appreciate you following the thread! I hope I can do everyone here proud. Its my first Corvette restoration and even though I'm on a limited budget to fund the project, I've really been trying hard to do it right instead of taking shortcuts.

Wifey had her Grand-o-kee - then -

So far today --



And out here -- 1/4" is a big deal --

No question that you are doing things right and avoiding the 'quick and dirty' restoration method. Nice work for sure...makes me think of my '84 Z51 I had until this winter.

Later,

Well after much debate with myself, I think I may just leave the car the otiginal black.

trm 84

Great choice.

says the guy with the black '84.

black is the best

I quite like it. The down side is that its difficult to keep clean and shows scratches and swirl marks easily. But when its clean and has fresh wax on it, black is just a standout color!
