I was merging onto the highway and gave it full throttle. The car started lurching and rpms bounced. I got a flashing CEL right then and the car lost pretty much all power. The idle is horrible. I just installed a tune less than a month ago, and I suspect that may have been the cause of this. I just pulled the spark plugs and they look fine. As for the coil packs I haven't tested them yet, just figured I would ask around here real quick. I have an oil catch can, HKS spark plugs, 5w40 full synthetic Mobil 1 oil, aftermarket boost solenoid, K&N cold air intake, intercooler resonator delete, and stainless steel fuel line. Any ideas on this? If anyone has had similar problems I would appreciate some advice. Thanks!
