My car stalls when I push in the clutch while decelerating

[Mr.]

Yup, cleaned the MAF.
BullittBoy- I got your PM. Thanks for the offer man, I'll keep you in mind.
Decided before I mess with the TPS I'm going to swap the stock intake/tune back in to try and rule out it being the tune.
It'd be a waste to go and spend a bunch of money on TPS/throttle body/whatever else before doing this for free.
I'll update when I have more info.

Good luck man.

I'm still having this same issue too, and am taking the car back to the tuner to have him check it out.

Chris when did you start having problems like this?

I've had these problems for about 1-2 months now.

It's stalled out about 10 times or so, and from time to time, my RPM's will drop to 400, then back up, and back down, and then back up upon decelerating.

Good luck to you too. Sounds exactly like my problem.

I've had something similar with my car ever since I made my Shaker scoop functional with my cold air intake. Mine was slightly different in that it would do it with the clutch pushed in and/or being and nuetral and decelerating about about 30-35 mph. Mine only seems to do it when its cooler out(denser air) and when the shaker is functional. I disconnect my shaker in the winter and never seem to have an issue. I was told it probably had something to do with the shaker being ducted right up to the filter and air being forced pass that maf when decelerating at higher speeds and the maf not being able to adjust or recognise whats going on so it would stall. I did that same as you and cleaned everything including the throttle body(gt500). I did have Bama adjust the tune and it helped out quite a bit but didnt fix it 100%.

Thanks for posting! One of the things that I was thinking about was how it only started happening when the weather was getting colder. Granted I only had the intake/tune on for about a month before that. Also, this is the JLT series 3 CAI. It has a 110mm MAF housing, so maybe the amount of air that thing is sucking in is causing something like what you were getting at.

Also, just checked all my ground connections - all good.

Sorry for the old thread bump

Just wanted to update this thread. The car hasn't stalled out since this thread was brand new lol. I did put my stock H pipe back in and ordered a new tune for it from Bama without telling them about the issue I was having.
I have changed my driving habit of letting the car coast to a stop with the clutch disengaged while in gear, so maybe that's why it hasn't died since then? I still notice the RPM's dropping low and bouncing back up when I decelerate sometimes, so the problem is likely still there. It doesn't bother me though since it doesn't stall anymore. So, for now I'm leaving well enough alone.
I'll update this thread if anything new comes up related to this issue.

Cool , glad its working out.

my 09 did this with the Bama Race tune (not saying it's the tune)... I fixed it be installing a supercharger and getting a dyne tune

I had the same exact problem that you are having, going above 40ish push the clutch the RPM would drop then bounce a bit then stall. Im pretty sure cleaning the TB fixed mine, it was horribly dirty behind the blades. However i also put a C&L racer on it at the same time it stoped stalling because i had a problem with my CAI leaking before. BAMA kept telling me that i probably had an exhaust leak but i would think you could hear it if it was bad enough to kill the engine.
