Rough idle question
Ok I either forgot what it feels like to drive my car cause its been so long or it is really idleing rough? Do most ls1 idle a little rough just sitting at a light? Seems like a little shake and my shifter seems to be shakeing more than it use to. Anyone feel these ls1 idle rough or is it just mine? Thanks

Depends on what's a little ... I get some ... veeeeery minor in my eyes. Is that what you mean?

Same here when I changed my stock plugs/wires with 8200 miles on them

Check your plugs and wires, also use a timing light on each cylinder to see that your coils are firing properly. We have found that the coils can be bad and misfire slightly enough to make the car run bad but not throw any codes.
