I've had this car for a year and love it. It was parked all winterand ran great but now its having issues. I replaced the battery did a tune up, new tps and now it seems to have gone into limp mode but I get conflicting answers as to whether or not this car has limp mode. I took it out for a drive and it has been choking up and sputtering for lack of a btter word and now it wont go barely up a hill, one of the spark plug wires is sparking so I will look at that tomorrow but that is what caused me to change the wires in the first place. The car starts fine. Any thoughts?
