Do you have a loss of power? Harder to start moving and barely creeps along in 5th? Because that’s what happened to me. I not only had the same problem, I replaced the exact same things as you. My car is now undergoing valve work at the shop. My number 4 exhaust valve was bent so I had no compression in the fourth, which means I was running on a cool three cylinders which is why the motor has such a hard time keeping idle. So it’s either, hopefully, plug or wire or some other electrical problem in one of your cylinders or, hopefully not, you have a bad valve which is giving you a hard time on one of your cylinders. Good luck, and let me know when you figure it out because I was wondering how often valve problems occur in these otherwise great cars.
