I picked up a 2wd '99 Ranger/2.5/s spd a couple days ago. When I got it, it would stumble when the RPMs dropped to idle, and sometimes stall. I found out the bulb for the CEL was burned out, so I fixed it and pulled the codes. It had codes for Misfire on #1 and #2, and excessive EGR flow. I was able to track it down to the DFPE and IACV. I replaced those and it's much better. It doesn't throw any codes now and doesn't stumble nearly as much when dropping to idle, however it does still do it. If I stay at lower RPMs, maybe less than 2500-3k or so, it's fine when returning to idle. Also if i shut it off and restart it, it idles smooth.
I checked the PCV valve and that seems good. I couldn't find any vacuum leaks either. It seems to me that it should be throwing codes given what it's doing. It's probably something simply but I can't figure it out. Ideas?
