Hello everyone.I'm currently driving a 2015 Ford Fiesta SE.Thought I had got a good deal on it.Turns out I bought someone else headache.I had the engine light come on ,a month after I had purchased it.It coded that the throttle position sensor was bad .So I bought a throttle body and replaced the old one.Next eng light comes up again this time saying catalyst system efficiency below threshold (Bank 1).I check the converter and it is hollowed out empty,I purchased a conv.the upstream and downstream O2 sensors.Still have a eng light come on.Now all kinds of different codes are showing up .a P0104,P2000,and P0420.P0001,P0109,P0200,P0902.the P0902 chk eng lite comes on and I decide to take it to the dealer and have them diagnose.P0902 is a clutch actuator issue .the dealer tells me the clutch actuator needs to be replaced.this is a $395.00 drop in the bucket and they have had car for like a week.I go pick car up and proceed to drive it...at 20 miles the light comes back on.the following day at 7am I'm back at dealer with same issue .Then they have it all day to tell me the car needs a TCM for trans .Which mind you has been on back order for a couple of months.I pick the car back up .Clear the eng light and drive it.20 miles goes by and eng light comes on again.now it throws a code of P0420,P0104,P2000. Now the engine light has came and went but showed nothing of the trans control module being bad .At this point I am flustered.I'm open for all advice and insights.Maybe someone can help me out .
