I've been having "issues"... a few months ago my car started chugging and bucking, and missfireing on cold start. It only lasts for a couple minutes. If I let her warm up until the idle drops it's pretty much gone, but still not perfect. I did get a check engine light a month ago, but it went away in a couple days. I took it to Matt at Peter Pan a few weeks ago, and he replaced the plugs and integrated coils... still happening. I got another CEL today after work. The car also feels down on power. Doesn't seem to be an exhaust cam issue. Any ideas? Similar symptoms? Anyone? Bueller... Bueller?
