I have a 1988 F250 with a 460 ci. motor. There was a problem with this model year with hard starts after motor was warmed up and Ford had a service kit sent out that would update and correct the existing processor. This kit included a new thermostat.
Dealers in my area do not have this kit because it is over 10 years ago. My truck was never updated and is hard starting after heating up.
My mechanic looked up the information on ALLDATA and the only info he got was to install a new EEC IV processor with revised operating strategy. This unit appears to be a factory supplied service kit that also includes a new thermostat.
There was an Authorized Modification Decal included with the kit that was to be placed in a prominent place. Because of the age of the truck, dealers do not seem to have any kits in their stock.
I am wondering if I will have to go directly to Ford but I do not have the slightest idea as to how I would proceed.
Any help would be appreciated
