replaced spark plugs with bosch platinum 2. which i know is supposedly not supposed to hurt it. after the fact turned on the car and let it sit for 30 minutes. took for a drive and has a hard idle with a shaky start but betters during drive. i took it at low speeds and at high and still there is a problem. i know to get my engine read which auto zone will do for free and i checked the plug wires themselves but they appeared normal. im completely lost and need advice. thanks
