Hey guys! New here...My 2006 Ranger XLT 4 banger's throttle response is off and inconsistent. Some days it seems crisp and immediate. Other days it seems like it's bogged down and takes a few seconds to really get going. All of this is from coming off red lights at a normal pace (no wot). The only thing I have done so far to try and fix this is the throttle cable mod which seemed to work for a little while. Idle RPM'S are at slightly above 750 if I'm reading it right. I've had a K&N drop in filter for years without any real problems. Flowmaster muffler...no problems. No lead foot. Also the CEL isn't on. Any ideas?
