Ok guys. I'm new here. So if this is not where this belongs. Let me know. I'll put it where it should be. So I'm completely lost at this point. I have a 2007 Cx-7 (2.3l Turbo). I bought it from my boss a few mommon back. He owned it when there was 47,000ish miles it. Currently has 187,000 miles. When I took possession of the car. Timing was in need of repair. Had stretched chain. So I had everything replaced. Not one part was left out. Let's go back just a bit..... Car sounded like a diesel. Had the ticking sound on start up. As many folks describe with their vehicles. About 5,000 miles before I bought it. He had a misfire in cylinder 4. At that point. My boss replaced all coils and plugs. Few months later. I bought the car. Started misfire again in cylinder 4. So I changed coils and pligs. Immediately after it jumped to cylinder 1. I did the coil swap test. No luck there. At that point I had the timing repair done. Again, replaced everything. once done, it drove excellent. No ticking. No diesel sound. Fantastic throttle response and shifting was on point. No issues. One week after timing job. It started misfire again. Cylinder 4. AGAIN. At that point I decided to remove manifold and do the media blast on my intake valves. My valves were filthy heavy carbon Build up. Once I finished the media blast. The valves looked really nice I reinstall everything hoping that would take care of the issue. It did not misfire continue. I have had the computer in the vehicle checked. everything is communicating as it should so I have no computer issues. I am at a loss. The car is in fantastic condition. I even took it to the dealer when I took possession of the car and had a few recalls fixed on the front suspension so it pretty much has a new front end. Transmission is in great condition. Not to mention the fact I have a lot of money invested into this car as it is. I am taking it to the dealership on Monday. When I called and talked to the service technician. He had told me that given the fact the timing was just done on the car that there is a high likelihood. The timing was not set one hundred percent cor it is possible that is the issue. Can't really be a bent valve given the fact that the car drove fine for a week and then started the same issues after three thousand miles worth of driving. So before I take the car to the dealership. I'm reaching out to the community here and hopes that somebody else has had the same exact issues and maybe has a fix. it's only going to cost me $135 to have them diagnose. After everything I've been through. I am going to just go out on a limb and say what's it going to hurt. I am scratching my head. My cat and O2 sensors are okay so I know that can't be the issue. When I did the media blast I inspected my intake valves for any of them being bent. They were not. I have not been able to look at the exhaust valves so I can't give any information there. Any help would be greatly appreciated guys. I'm not getting rid of this car. I'm in it for the long haul I understand there is a lot of miles on it. But I am dedicated to it and I know once I fix this issue it will be okay. I have already gotten myself prepared to just replace the motor as it is. if I have to do that I will just pull my current motor out and over the course of the next few years I will fix that motor and heck who knows even make it extra special lol. Put it in a crate and keep it for a rainy day. Or a racetrack whichever one comes first. But in the meantime here goes I hope you guys can help.
