After 3 weeks of no driving, my car is finally up and running. The start died on me that's why I haven't been rollin". Anyhow, I was wondering if anyone can tell me how to make my car run better right off of cold starts. Once the engine is warmed up, it's flawless. If I just start to drive it without warming it up--it just seems a sluggish. I've put in the bosch 4-prong spark plugs and cleaned out the EGR stuff, but I don't know. It's not as smooth as it used to be. I have 105K miles.
