Weird Rev Issues (Legit issue this time)

Hey,

 

My Legacy has this really strange issue. When I am cruising at free way speeds and pop it in to a lower gear, then floor it, the revs will just jump and sit at the same rev while it acclerates and eventually will continue to gain, but this doesn't seem normal at all. Here is a video of what I am talking about.

My car has COBB DP, GMS exhaust, and COBB AccessPort running the Stage 2 map. Any suggestions of what could be going on would be very helpful.

 

Thanks!

EDIT!Just wanted to let everyone know, it was the clutch! Don't bother reading the rest of this, my clutch was toast, with big thanks to the previous owner for doing that.

MT or AT? If you have a manual your clutch is shot. If it's an auto i have no idea.

I have a manual. Is that what it is for sure?

something is wrong i thought if clutch when bad it will just rev and not gain speed try putting it in fifth gear on free way and apply power if it just revs clutch should be bad or put it in fifth again at a stand still and release clutch if it takes a second to die it means its bad once again.

I have done and the revs shoot up, but it still accelerates. I'll doing to the 5th gear thing at idle though.

where are you in west jordan? i could maybe come check it out

Just west of Jordan Landing, or west of 78th and Bangerter. I think I am going to take it down to Solid Autoworks and see if they can do a little diagnosing for me. I really hope it's not my clutch.

Outside

What?

Haha sorry it was suppose to be text to friend did you try letting it die in 5th gear?

So I think it has something more to do with timing being pulled because derkle13 and myself both had the same issue and we were both auto. We both had a learning view done on our cars when we were ap stg 2 and you could see timing being pulled around that area. I think it might have something to do with heat soak.

I have yet to install my heat shield so that might be it, and it does have 77k miles, so timing belt probably does need to be replaced soon. Reason I don't think it's the clutch, is because it's an upgraded clutch, and I don't drive it hard at all.

I would expect it to rev higher if the clutch was going. The fact that it pulls pretty well up to that point makes me worry about tuning as well.

Its weird that revs stop moving but MPH does

I thought the same thing as SurlyOldManMN , so I uninstalled my AP, but my car would just die after the uninstall. I think that was because I had just barely uninstalled it, so I just reinstalled it and it idles fine. I have no clue what could be going on.

do you have an modification you don't know about?

There were at first, but not now, at least externally.

I noticed this probably after a week of having it, but never thought anything about it.

I'm going to try uninstalling the AP again today. Or maybe install the Stage 1 map.

The only thing I could see making you die would be your turbo back exhaust but honestly that shouldn't make your car die with the ap uninstalled.

.... Exhaust making a car die .... No. Ap or no Ap it won't die.

When you uninstall the AP, the ECU will go into a reset cycle. I believe you have to wait ~120 seconds before trying to run the car, or it just won't. 120 may be longer than necessary, but yeah, wait a while after unmarrying it and try to start it up. If it won't start after that, something is horribly wrong.

 

Have you checked all your vac lines/etc? No CELs? Almost everything I can think of here would cause a CEL.

What is CEL? Sorry, I'm a little bit new to the game.

This would make sense because I started it up right after uninstall. I'll try again this evening, and also check all my lines. I am really hoping it's the tune.

Check engine light is not on.

so you said it died when you stared it. died as in it wouldn't start or it would start up then die?
