First post on here
I've got a 1994 ranger 4.0 5spd ext cab 4x4
So for starters when I start the truck when it's cold it turns on then idle up then idle down and dies, now if you hold the throttle on it will fluctuate in rims but stay on. Then after about a minute it the rpm goes up and steadys out and you let off the gas and idles fine for the most part.
Then after driving for a couple minute the check engine light goes comes on, also when you go past 3/4 throttle when driving nothing happens it kinda just bogs down. So I got back to check codes and I'm pulling a code 176 which is oxygen sensor sensing running lean. Not sure if it's all related or not. Any help is appreciated! Thanks!
 
Maybe the fuel filter needs changing. I got a lean code as well, just yesterday. 2003 4L 4x4 auto. I'm going to replace my filter and see what happens. Probably needs to be replaced anyway.

Edit: Spencerisford, if you haven't found your problem yet, I suggest you search this site for "PCV elbow". That's what my problem turned out to be.
