Well, about three weeks ago, my car started having idle problems and it took a couple of cranks to get the car started. I had recently replaced the coils, wires and spark plugs so it wasn't that. So, to prevent the car from stalling out because it wouldn't hold steady while idling, I had to rev it about 1000+ RPM. Sometimes I would see if it could idle on its own and it was very rough and jumping between 200 RPM and 800 RPM, it would trigger the check engine light which was P0300.
I replaced the timing belt two weeks ago because it was over 90,000 since the last change. Since that was a bigger job that I could handle, I had a dealership do it along with the water pump. Anyway, that didn't fix the idle issue but the car did run a little bit smoother.
This weekend, I replaced the EGR valve and that fixed it. I flipped the old EGR valve over and shaked it out and a bunch of carbon deposits fell out. Nothing big though. That was puzzling. The insides were very dirty though. I removed the screws holding the two pieces of the EGR valve together and I manually depressed the valve while shaking the EGR valve. Out came a small piece of metal... it was thin and small. I shook it again and another piece came out. That was it for weird pieces coming out but I don't know where those pieces came from. They were about 3mm odd-oval shaped and very thin. Covered in carbon deposits but the edges were rounded.
