I have a 2004 Kia Optima and the check engine light is on. I got a diagnostic and its telling me it's the TPS. At first the car was drivable but now it's worse. I cant go past 20 mps and the car accelerate while driving. All of this happened after I got the water pump fixed. The water pump and timing belt were fixed at the same time
What makes this problem better or worse?
