Shane,

I think we need more information: How high did the temps go? &n= bsp;what were the other temps when the "spike" occurred? What was the= rpm and manifold pressure at the time? Can the condition be duplicat= ed by duplicating the condition at a different altitude? Did the spik= e occur simultaneously on both cylinders? I suspect that one spark pl= ug in each of the two cylinders stops firing, perhaps because the mixture i= s excessively rich (but possibly lean) under that condition.

Hello All,
I have a client with an ES that is experiencing an EGT temp spike on =3D=
cylinders= 4 and 5 on final. A while back there was a brief discussion on =3D<= br style=3D"font-family: monospace; font-size: 13px;" class=3D"">what causes this phenomenon, but I have not been able to= find the thread =3D
again. Could someone let me know what causes this and what shoul= d be =3D
d= one to prevent it? Otherwise the plane flies great and temps are normal =3D=
in all fl= ight modes.
Thanks,
