Good evening, sorry about the lengthy post I just really need some help or information.
I have a 2015 F-TYPE R with 60K miles on it (Not under warranty). Had for about 2 years no major issues, previous owner I bought it from had it tunned with the lower pully from J.A.G.S tunning group. Over the past few months, I've had a lot more issues. Recently had a check engine light that flagged a fuel injector problem, I replaced all 4 injectors on bank 2 and all 8 spark plugs. Almost a month later replaced the driver side catalyst. Since then, the car has had a rough idle during the open loop/warm up. After it warms up rpms drop, and it is as smooth as a whistle and drives with no issues. At the time it was throwing no codes so mechanic believes that it is a software issue as a result of the tune. Took the car home and almost another month later I get a P0302 code for cylinder 2 misfire. I've only put ~70 miles on it since it has left the shop with one hard night of driving (next morning threw the code). Just wanted to pick you guys brains on what do you think it could be, Tune? O2 sensors? Mechanical Issue?

- Thanks in Advance !!

Don't know but have never heard of JAGS Tuning group? I use and recommend VAP. Hundreds of people have used their tune and pullies without problems.
I would go back stock until you get the car operating properly.
