4400 RPM "LAG" in third gear 3rd Gear

So i floor it and merge onto highway, at somewhere between 4,100 and 4,400 RPM in third gear the RPM's "LAG" and hover there for a sec... Idea's?

someone said it's an EGR thing, i doubt it's a clutch tranny thing as the RPM would slip it to a higher RPM and not likly to be a torque converter because again it would slip to higher rpm upon slipping.

I thouhgt it might have to do something with the VVT SOHC to DOH-cam switching that this engine features delaying in it's 3200 RPM (or something like it) switch over.

FPR? fuel delivery idea's?

Could be the T C locking up before it shifts to 4th...:_wrench:

Just to be safe I'd check tranny fluid level, make sure it's topped off. Good Luck

Disagree... when the TC locks up (in 2nd, 3rd, and 4th) it will lower the engine speed by a couple-few hundred rpms, then again when it shifts into the next-higher gear.

Low engine oil will affect the tranny performance, so check that.
