last week my car was running fine, this week, it was acting rough, i talked to my mechanic, he said it was the spark plugs and wires, i replaced those and it ran better, but i noticed a lag of power between 15 and 20 mph, when im sitting in drive and at a red light, it dies to barely running and the rises to 1200 rpm, then back down, when i put my foot barely on the gas pedel, itll chug then be fine until i take my foot back off, i also just changed my fuel filter because my cel came on saying too lean, after i changed the filter, it went off. i almost forgot, when i start in the mornings, itll die, then run fine and if i slow down fast, it dies
thanks for any help you give me, sorry its so long
