So my car was tuned at laroccas when the previous owner had it. The car has a chip (not installed) burned for 94 octane... they dont sell that anymore. The car has a rough surge from time to time, a couple hundred rpms. Sometimes not often, it will just idle at around 1500 rpms and i will have to shut the car off and turn her back on to get her to idle back to normal. Now i dont know if thats a seperate problem from the tune or not. Now the most recent issue started in April I noticed a loss in power and the car runs like absolute dog s h it. Its almost as if it was a carb car and it was backed up or something. Its hard to explain but sometimes it sounds like its backfires and like it needs to be opened up and blow all the s hi t out of the engine, but i get on it all the time and it still sounds choked up. Could it be the new ethenol BS gas? I dont know what to do I cant afford another $600 tune could anyone locally help me?
