hello everyone, i need some help, and maybe somebody here can help me, i have a 1992 convertible corvette, and this last month it's giveing me some problems, let's start from the bigining, well one day while i was driveing my car on my way home i was waiting on a light and my car was like it was loosing power and wanted to turn off the engine the RPM where ok but the engine was like if was losing all his power while it was waiting for the green light and the oil preasure gauge gets crazy moving fast up and down like crazy so the car looks like if it's going to turf off, but keeps on, when you start runing it's ok but if you stop in a light the car start to vibrate you can really feel it, the car it's moving due to the vibrations coming from the engine, like if it was drown or smothering, and i can see a kind of smoke coming up from the hood and smell like if something it's burning, but the worse thing it's the right axhaust sistem it's like if is not working well, like if is drown or smothering too, and a lot of smoke come outs from the exhaust sistem something really amazing plenty of smoke, i think the smoke coming out from the hood it's due maybe a oil leaking problem but the others things i can't find a reason. i know my english is not perfect but i try to give an explain as good as i can

 

It kind of sounds like a plugged cat on the right side. That wouldn't explain the oil pressure guage unless you are losing pressure for some reason.

Any codes?

 

Did you check for possible codes? You didn't indicate if a check was done on the other forum. Maybe your SES light is out?
