1997 GT40
The last 2 times out, the CEL has been on at idle, infrequent and random. Temp gauge was reading 160 and the oil pressure at idle is a bit under 40 psi but occasionally dip to 20 psi.
The engine went into limp mode once but cleared up, and we skied for another hour.
My first though was it was because of the multi viscosity Shell Rotella T; this was the first time I had used it.
Ive read its either the oil switch or the temp switch.
Im gonna try to pull some codes of the engine computer.
Any ideas,
Thanks
Shawn

Shawn,
There is a great GT40 trouble shooting thread on here. I believe there is a sticky at the top of the page. However, it sounds like you may of found it with the two things you are looking at with the light coming on. There are a couple of GT40 manuals in the reference area also. One is very new for the older GT40's.
I hope this helps,
Donald

According to the manual the ECA wont store codes for those sensors.
I believe their pretty cheap I would replace them. One at a time that way you know which one was bad.
I think the is an ohm # in the manual for those you could try that.
