Pulled the codes on my 86 F150 302 the other day.
The codes were
23
31
a code for the engine coolant temp.
and a code for the PIP. Changed the PIP and the code disappeared.
However for the TPS. I tested it as the manual said to and it checked out. Why would the code be there?
Also for 31 (EVP out of range) would blocking off the EGR fix this problem. I really don't care about emissions, and was hoping to just have a plate made to insert between the egr valve and the intake. If not what would I have to change/repair to remove the code.
Thanks
