SOURCE: wiring

It is not downloadable, but the library will probably have a Mitchell repair manual with wiring diagrams.

1986 Ford Bronco, 302 EFI. Surges in idle. Speeds up then slows down.


Probably a loose or missing vacuum hose. Check the vacuum diagram under the hood and look for loose or cracked hoses.

If this is a regular conversion then any adaptor plates you need will be available at speed shops that specialise in this conversion.

1981 ford bronco failed emissions twice


Look behind the motor, next to the firewall. There's a vacuum check valve that keeps the air gulp pump from pressurizing the crankcase. Mine was shot; had the same symtoms. Also, make sure that the EGR valve is closing at low idle.

You don't need an engine light to check the codes. First, do a KOEO (key on, engine off), but, let me tell you, when this happened to me (1986 Full size with 302 EFI, multiport injection) NOTHING showed up. No one, not Ford, not emission specialists, nada, knew the vacuum check valve existed.

By the way; are you getting motor oil in the air filter housing?

TO IDENTIFY PART ON '93 FORD 302 EFI V-8 USING EXPLODED VIEW DIAG


Sounds like it is the tube to part of your emissions equipment. It usually goes to another hose that goes to a one way valve from the air pump for the air injection for your exhaust gas recirculation system. These are prone rust and can be purchased from Ford for replacement.
