These cars have feelings! Calling it a Mistake hurts...
My experiance with cars crooking after running for some time leads me to the fuel pump most of the time. As for the miss, 95s will not give you a code on misfires. I had a bad coil pack on tour #2 and the EEC didn't know it. I heard the miss in the exhaust so I started to pull wires one by one until I discovered one of the coils (there are 3 in the pack) was dead on one side only. Holding the wire next the opposite tower and receiving its spark made the miss go away.
