Hello again. I recently had a fuel injection flush done on Tuesday. Check engine light came on Tuesday night. Starting Wednesday, my car started to shake. Last night while driving, it shook during my errands. Took a while to get to 6th gear. Took it back to Mazda this morning and they were going to diagnois. I just got a text from them stating that is was an open fuel injector and I need that replaced along with the spark plugs. My question is, would an open fuel injector be noticed during the flush or would the flush have opened a fuel injector?
*My car is a Mazda 2014 CX9 Grand Touring. The reason why I got the fuel injector flush done was because I started smelling a rotten egg smell and I googled. Mazda said to start with the flush to see if that would help the problem, which it did since no more smell. I also had a new battery installed on Monday, not by dealer.
