So my 2006 SS SC has a bad really bad idle (jumps from 500rpm to 2300) and lean and rich codes as but i changed out my MAP, supercharger inlet sensor (by the throttle body) as well as both o2 senors but once i did that 30 codes came up with voltage and even the o2 bank 1 code which i replaced them for but it still dies and rough idle anyone know whats going on with my bolt ?

 

try posting the code number and definition

 

Thats what mine did when my cat was clogged, cheapest way to test is to just crack the seal between the cat and the headers, you'll have to replace the "paper" seal but that's what id do next.

PRO TIP: if you get a message saying "engine power reduced" and your car goes into "Limp Mode" you've got maybe 5 miles before shes completely clogged and wont even start.

 

Was the idle jump issue the reason you changed all those sensors? Did you have any codes before changing the sensors? If a bunch of codes came up after changing the sensors I would guess either faulty/wrong sensor, bad connection, or damaged wire(s).

 

ok all so i replaced those sensors listed above due to the codes being popped up as well as new AC plugs and coil packs then i thought it would be the fuel i i changed the filter but now only one code comes up and its P0300 anyone know that that could be ?

 

How do the Spark Plugs look?

 

they are brand new AC delco
