I have a 93 Formula with a severe miss that has developed over the past few months. Doesnt throw any codes, but has a bad misfire on two cylinders on the passenger side throughout the rpm range.
Before the miss set in, I noticed an exhaust leak that grew progressively worse , which I traced to the passenger side exhaust manifold, above the 02 sensor but not the manifold gaskets. It wasnt major so I ignored it. Then she started missing, first only when the car was hot, then all the time.
I'm 99% sure its a cracked exhaust manifold, and am wondering if this could cause a valvetrain issue (burned/bent valves).
