Stalling when engine is warming up
Hey guys,
I recently bought a 99 Ranger and I'm currently having a bit of trouble during the first few minutes of driving time. When I start the truck up it has a very bumpy idle and over the past week it has stalled on me a few times. Usually this is when I have the clutch in and am coming to a stop. After about 10-15 minutes the engine's idle has evened out and it runs smoothly. I'm running on 87 fuel right now (I was planning on filling up with a better grade this time around to see what difference that makes).
Any ideas as to why this only happens when the truck is getting warmed up?
Thanks!
