They have done a leakdown test, Cylinder 1 showed 35%. With swapping injectors, cylinder 1 is now normal and the cylinder they switched now has the issues. Car has been in the shop for two days and only just over $100 is labor so I’m not complaining. They seem to be pretty certain it is that injector. Valve lash was checked, timing chain checked, cam timing, everything you can without taking the whole engine apart. All checks out. They’ll know by tomorrow if the new injector solved the problem. I’ll ask them about the scan tool and see if they did any tests with it. This is the fourth time this car has been in for misfiring. I really hope this fixes the problem.
