What is making car idle rough and have no power when pedals to the floor
Car don't seem to want to go the harder you press gas less power you get. Idles rough when parked. Putts in idle or while accelerating. Changed spark plugs the spark plug wires the coil packs the fuel filter the cat is off. Have checked the tps also. Don't know what to check next
First step - have the stored fault codes or check engine light scanned - for free - at any local auto parts store; Advance Auto, Auto Zone, NAPA. Then, post a reply as 'add answer' with the specific code for more assistance.
