Ive got my brothers 98 Ranger 3.0 manual 4x4, that Im trying to fix while he's in Iraq.
The problem is that when you start it for the first time in the morning it will usually start all bogged down for a second and die, then starting it again, will start up all bogged down on the verge of stalling for 2-10 seconds, then the idle jumps up and it starts running fine.
It only does this on the first start of the day, or if you don't start it for 8 or more hours.
The other problem is that when youre driving it and then take it out of gear, the rpm stays up at where it was when you were in gear, and doesnt return to normal idle until you come to a complete stop.
I got 2 codes off the computer: 171 & 174.
Both are: Air/fuel ratio too rich/lean for PCM to correct.
Ive cleaned the Mass air flow sensor and replaced the Idle Air control valve, and nothing has really changed.
Any help would be musc appreciated-
