Alright I own a 1994 Ford Ranger 4.0 V6 4x4 with about 210k miles and I have some runability issues. They started around 175k and have slowly become worse overtime. It runs and drives fine when its cold but when warmed up it drives ok not great but ok and if it sits for about thirdy minuets or so after driving it for a bit it sputters out and wont run unless I keep my foot in the gas peddal and hold it for about ten seconds before it can hold a decent idle so i can drive it but surges at a stop and seems to jump around 800 to 1000 and jumps while at a stop . I have read other questions with other owners with the some problem and I've changed plugs, wires, coil pack, fuel filter, cleaned the MAF, cleaned the idle air control valve and changed the fuel filter as others have recomended to fix the problem and have had no sucess
. Not sure what to do now I am hoping someone has had this problem and fixed it.
Thanks for reading,
