could be plugs,wires,coil or an injector. you need to go to a shop and have them check it for you.

I have the car in the shop twice this week. Already had a tune up done within the last month. they replaced a throttle sensor. because that is what the computer said is was wrong. Husband went to pick up the car today and not even 15 mins away from the place it did it again!

find a new shop. the computer sends you info that you need. it never identifies the failed part. tps would not cause this condition.
