Just was surfing rockauto and found the repair manuals on cd for like $23.00 very cool site
Thanks again

O2 sensors replaced rough idle gone power back..it. Seems as thought the passenger side was original equipment 22 years old.
Thank you again the forum was my dictionary
On to the other issues 😁

I completely understand
Thank you again I already did the plugs as I mentioned with my findings
I will put new o2s hopefully this cures the roughness.
I will let you know.

Thank you so much for your imput I’m looking forward to changing the o2 sensors keeping my fingers crossed. the car has 140,000. On it
Do you think I should just change the one bad side 02 sensor.
On the other side the plugs are that perfect greayishtan color

I just got this car with very little history the check engine light does come on
But like I mentioned the passenger side plugs were blacki like it was running rich
Runs great when it’s cold though

1995. Corvette idles rough at a stop and seems to surge a little.
Removed spark plugs and noticed the drivers side plugs look great but the passenger side was black like it was running rich on that side. Any thoughts? Can an o2 sensor on the passenger side do this?
