Friend has a 88 Dakota v6, auto, 165k, 4x4, --
Recently started setting code 13, only.
Filled with Antifreeze (non-related)
Replaced Air cleaner and cleaned housing and tubes
Added 1.5 quarts of ATF (non-related)
Cleaned throttle body inside and out with Seafoam
Checked wires and hoses for cracked
replaced air breather and hose
replaced PCV valve
Charged a/c - (non-related)
Adjusted ac and alt belts (non-related)
Put seafoam in gas
treated intake with seafoam
This truck runs 100% better, starts better, and idle speed went up about
500 RPM at idle,
se we adjusted it to spec.
It runs great, ac works, and doesnt miss, etc.
Ran about 50 minutes on road and idle,
and didnt set codes.
Then it set code 13 again, and comes one almost instantly when cleared.
Im thinking MAP sensor - but the one listed has a picture with three wires
going into it and a hose,
and the one on this truck doesnt have a hose tube on it? - Right on the
side of throttle body?
Other suggestions are PCM?
Anyone have any help and great ideas on this?
