OEM PARTS KITS MOD IAC
Just received OEM parts kit to mod/fix IAC Idle issues 1987 XLT 5.0 pics below p/n and contentsFOUND THE ISSUE ITS THE IAC..... This whole truck is rebuilt new... so was puzzled
IAC is ford Achilles heal,,,it gets contamination easily then it sticks and starves the engine of proper oxygen...
Ford put out a fix on later models to address this.. iTS A METAL PLATE that fits between the IAC and the throttle body right side.
it has two adjustment screws and acts as an air bypass to prevent this sticking. I am ordering one from ebay about 60$
