Question about 2004 Ford Ranger
Lately my ranger has been idling at around 500-600 rpms and dies frequently due to low idle. my check engine light has come on and then the problem started around the same time. while driving anytime i slow down and stop the idle drops below 500 rpms then dies. i think it might be an electrical problem maybe with the spark not reaching the cylinders
My ranger was doing the same. I have the 4.0 engine. Installed a K&N filter (about $65.) and idle is now steady at 750. Gas mileage and performance also improved. Hope this helps.

I figured out what was going on. supposedly on ford rangers the Idle Air Control Valve (IAC Valve) goes bad. i got a trouble code looked it up and sure enough it is the IAC Valve. Under 100 bucks for the part
