been having trouble with my car for over a week now idling really rough and no acceleratingwith shitty gas milage and done everything i know to fix it: swapped plugs, checked injector, new fuel filter, checked coil pack, but now it wont even start, i live in lexington, ky, in general where is a good place i could take my car to get checked out and fixed besides a chevy dealership?

 

Have you cleaned your Maf sensor.
Have you refilled your tank aain lately ,could be bad gas(lots of water in it or ethenol content to high)

You could try filling it with good gas and putting in some gas line antifreeze or conditioner to disperse the water if thats the case.

 

already cleaned maf, run injector cleaner and seafoam through the car b4 when it was runnin and hav put new gas in it

 

My 06 ss/sc did this... It ran funny for a week then finally stopped running totally. It would idle like crap and get shitty gas mileage. I had to replace the MAF.. Cleaning it did not work. You don't have any cels? Mine did eventually get an air sensor cel right after it died.

 

sry, i forgot to mention that i got a p0300 code which means random misfire when it was runnin and the cel is still on so i could hav got new cel code since
