this is my issue. most of the time my car performs sluggish. Its feels like i have a ton of weight in the trunk. Only once in a while it performs like a new car should, takes off and feels really smooth like nothing holding it back and fast and this is only temp. Last time was about 2 days ago then before that was about 6 months before. I have changed one coil pack, spark plugs and timing belt as i bought it used. It has just started to idle a lil on the rough side again but this is new to the issue.
Any insight would help.
