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 waswaiting for the green lightand 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

 

Is it throwing any codes? Service Engine Soon light on?

 

no lights come on

 

Could be a fuel pressure issue, faulty regulator maybe. Checking the fuel pressure would be a good start.

 

the fuel pressure could be the cause for the engine vibrations but what about the problem on the exhaust sistem, i wonder why the right exhaust sistem doesn't work

 

Plugged cat?

 

i allready checked undre the car, cause i thought something was broken for that reason it was loosing pressure and not working, but everything looks fine, and inside the exhaust tips it's clean, nothing there

 

Welcome into the forums there miguel.

Wow! You got that all in one sentence!

 

If you had a plugged cat the tips would probably be clean. Have you looked under the car after a while of driving in this condition to see what color the exhaust pipe is leading up to the cat or is the cat glowing under this condition?

 

I also think it would get glowing red hot forward of the cat. Meck I think made a post on checking engine vacuum to check cats but I cant find it. Maybe he Will see this and comment.
