Slow Throttle Return Response

Had a Ranger way back when, and decided to buy another one last week. 2011 model, and don't know if I really have an issue or whether the situation I'm going to describe is normal. Don't remember it being that way on my early 90's truck.

So the gist of the story is this - Manual transmission model, 4CYL. When I throttle up to around 3k RPM, a pretty usaul shift point, then clutch to prepare for the shift, there seems to be a delay in the engine RPM drop, so unless I wait for several seconds with the clutch depressed before re-engaging in the next gear, I am letting the clutch re-engage at a higher RPM level than I consider normal. This bothers me from several perspectives, one being clutch wear, the other unrelated, having do to with simply a delay in deceleration when letting off the gas.

Thoughts on this?

I know this response is very late, but mainly for future search results.

I had this problem with my '91 3.0 with a manual. My idle solenoid went bad. I disconnected the solenoid and bam, no more problem! I do have to manually hold the idle up until the engine is warm, but for me that's not a big deal.

Hope it helps... someone... someday!

let off the gas a second sooner before your shift. the engine is unloading, can now spin up, and isnt dropping as quick because of it.

I don't know if this is what you are experiencing but the newer Rangers don't use much engine braking when you let up on the accelerator pedal. This tends to make the rpm drop slowly when shifting. This is suppose to help reduce emissions.

I have a performance tune on my 02 Ranger that changes the way it decelerates and takes advantage of engine braking. When I return the tune back to stock for emissions testing I get this slow drop in rpm between shift and it drives me crazy. I also don't like it when I let up on the accelerator pedal to slow down and it doesn't slow down very much forcing me to use the brakes more. I am very happy when I can get it back on the performance tune so it can have the good driving characteristics again.

This is normal. it is called the dashpot function of the Idle Air Control motor and is designed to prevent jerky shifts, as you would have if the IAC didnt have a dashpot function

I also have a 2011 Ranger with the 2.3L motor and a 5spd tranny. It does this same thing - engine is very slow to rev down when shifting. Annoying, but I think it's normal and a "feature" of the emissions system. I haven't attempted any mods to change it...
