Wrapped up a few more loose ends on the Coyote swap. I have been having issues with the car when it gets above 5k rpms. It hesitates and falls on its face.
Problem with that is that the Comp Stg 3 cams are just getting warmed up at that point and I should feel an increase in power, not a decrease. I went back and forth with my tuner and he said the logs to him look clean. This led me to reach out to another tuner for a second opinion. Second tuner said if the logs look clean it must be a mechanical issue. I’ve gone through the setup several times trying to find a mechanical issue. I finally found an issue. The one coil pack had an intermittent issue on cyl 4. I’m guessing this was getting worse because the car kept running worse. I replaced the coil. I also replaced the leaking coolant reservoir, tightened up the x pipe because there was a leak where it meets the headers, discovered the JLT catch can wasn’t properly connected to the manifold (I’ve had this off and on a dozen times while troubleshooting. It was installed correctly at one point.), and I took the time to fasten the air filter shroud with something other than zip ties.
In the end, it all worked out because the car is now running absolutely amazing. I was surprised that I have had multiple new parts fail almost immediately with this build. One crank sensor, the coolant reservoir, and a coil pack (OEM). I guess quality is a thing of the past. One of the reasons I bought everything new was to limit any possible issues…..that isn’t working out so well!
