Ok, my 2000 SS idles rough, surges kinda. And at low rpm its real rough and sluggish but if I stab it it runs fine. Had removed the screen on my MAF and everyone said that could be causing the codes P0300 and P0134. So put a differant MAF on same thing. Checked coils and plug wires they're all fine.
And it smells like its running rich. Help guys please I'm going crazy. Sorry so long. Thanks, Have a blessed day.

mod list would help.


probably o2s are shot..

 

does it say "insufficient switching" when you scan it?

 

02's were done about 6 months ago. And its not acting the same as then.
mods are lid,cold air extension, lts, rear 02 deletes 3.73 gear,tranny work, that I know of bought it used.

 

doesnt matter when the o2s were done..

your using o2 extensions for the LT's arent you?

 

No used the corvette ones and checked them they arent burnt or chafed in any way. thanks keep the ideas coming

 

do you have a stock maf on it right now?

 

Yes its a stock MAF. I'm putting new o2s in since they were still under warranty. And then I'm sending the computer to get tuned. Or should I get it
dyno-tuned. Thanks

do you plan on doing any other mods for a while?

if you plan on doing something, hold off on the more expensive tune...

if its going to stay thi sway for a while, dynotune it..
