Hard accelerating question?

I notice that when pass 4000rpm on hard acceleration it feels like it bogs ever so slightly. At first I thought it was the advance trac so I disabled it but sometimes it still happens? Another way I could describe it is it almost feels like the wheels spin for a fraction of a second. Could a glazed or slipping clutch cause this? It's a 2013 with 9000km on it. Any input appreciated.

Not really bad at all. But I do notice it. I called my Ford dealer and they where like, huh? It does what exactly? Lol. It's my first manual so I have no idea if its common or not.

It could be clutch slip, ford dealerships are useless you can get more knowledge from people off of here. Its actually a common problem in the mt82s it could be the shift fork... I would have to ride in it to see

Yea they hate modified cars too, can't expect anything from them. But your problem sounds like it could be clutch slip. Is it in every gear?

I don't think so but I don't get the chance to push third and up to often. If it was clutch slip is there anything they/I could do without replacing it? From what I can tell it doesn't happen all the time and its only in the higher rpm range. Thx for your help. : )

Not really because it could be a multitude of things. Bad clutch pads, bad shift fork, or the plate that holds it could be bad. Or maybe its fine and just breaking in could be a multitude of things. Let me know what you do or if you need anything else

Clutch slip? If so, it should be in every gear if he floors it. That would be an apparent problem. Unless he's abused it, it shouldn't be an issue. Clutch fork has to do with shifting into and changing a gear, no idea how that could affect it... You shouldn't have a slipping or glazed clutch at your mileage unless you've been riding the clutch pedal and smelling clutch material.

This sounds really weird, but do this... go under the hood, pop open the fuse box. Remove fuse #47 for around 10min, pop it back in and take it for a ride. Let me know if the car feels perkier or not.

I'd love to blame it on a slipping clutch, believe me. It just doesn't seem likely.

Bogging at the start of first with 2.73s is a very common issue. You either have to slip the clutch like hell, get steeper gears, or accept it. In that vid, I noticed a weird pause near the top of 2nd gear, but that's all I could tell right off.

I definetly noticed it on the top end, and it matches with what OP was saying about it bogging at over 4k, i don't think its the clutch slipping. I honestly have no idea what the problem is.

Thanks for the help. I did learn how to drive stick on it that's why I thought maybe I glazed it. Once I down shifter from third to second and didn't rev match and the car shot me forward a did a little chirping of the rear tires when I was learning but other than that I'm very good to her.what will pulling the fuse out do? I've got the day off and I'm gonna go do that in 10. Thx guys.

Not a slipping clutch at all

If the clutch was slipping you sure won't get a bog, The engine would rev up extremely fast all the way up to the limiter. I can't tell you what is causing your bog but I can assure you it ain't a slipping clutch.

I checked out your and its not the same thing. I'm not even sure if I did a vid while driving that anyone would even pick up on it. It might just be a drivers feel. Thx.

That's a relief, it definitely doesn't do that, whew, maybe its more of a software thing? I'm gonna try the fuse but it decided to f in snow today and I don't have my snow tires on. : ( Thx Ronnie.

My transmission was replaced due to bad synchros and faulty forks on all gears I never had a bog or anything except maybe in first but that should be due to the gears. Maybe type of gas? Lol idk

Mike, pulling that fuse resets the PCM. Some guy on another forum had a mysterious "reduced power" issue from his MT82 car. Couldn't figure it out and tried that, it fixed it. I guess some parameter in the PCM gets messed up and you need to clear it in order for things to start working right.

It could be this, Just something to think of.

A weak coil pack could very well be the problem, Fires the plug fine at the lower RPM's and just plain driving. When under full throttle it is not spitting out enough juice to fire one of the plugs. All six coil packs need to be tested to find out if one is not up to snuff. I'm pretty sure the dealer will not want to do this as long as your car is running. I;m pretty sure this won't throw a code. Somebody may correct me if I'm wrong on throwing the code.

In the old days when we only had one coil and a bunch of wires it was easy to track down. Usually a bad wire. But now you need to track down ((IS IT A BAD COIL PACK?? )) Ain't nothing easy any more.

Well I just removed fuse 47 and I will wait 10-15 mins. It has stopped snowing for a little bit so I can hopefully get out and try it shortly. Thx Sanguin!

That's something I didn't think about either! My friend had one replaced on his old t bird. Is there an easy way for them to test for it?

Easy if you have the equipment

I don't know if they can be tested without removing each one from the car. If they need to be removed it would be time consuming. I would think that a misfire would throw some sort of code but I really don't know.

Just be very careful driving in your "SNOW" This is something that can really wait until it is totally dry out with no Chance of hitting some icy spot.

The trouble is that the dealer will probably connect it to a scope and of course it will not show anything wrong because the engine is not under a load at high RPM's.

I think what you feel as a bog is a misfireing of a cylinder and under a heavy load at speed with wind resistance adding to the load and at higher RPM's.

My personal opinion is if it was anything in the PCU it would be a problem all the time and not just at 4,000 + RPM's.

Well it started snowing AGAIN, so ill have to wait a bit before I can get out. So I was reading up on faulty and intermittet coil problems and it sounds exactly what's going on in my situation. It's says that an intermittent coil problem won't normally throw a code and won't cause any issues under normal driving, but when merging on a highway in the upper rpms is where it will become more apparent such as a slight to moderate hesitation. If pulling the fuse doesn't improve it I think its definitely pointing towards a coil problem so far.
