New symptoms. Wants to stall

[Rides]

Hey gtrcers, need help with my car and hope it's not too serious. I was driving today and noticed my car wanted to stall out while I was going at a constant speed. I was going about 60km/hr and the rpm dropped for about a milli second. While I was at the lights it did it again. It just dropped and went back up to idle. Literally for about a milli second. Just down then up. I haven't changed my fuel filter yet and not sure if this the cause of it, or fuel pump? Please advise. Thx

Hey guys, I'm so bummed. I was driving home after work and my car is really acting up. I'm lost of words and very worried on how to fix this problem. First ten minutes of driving everything seems ok, then it starts to happen again. As I'm driving the car wants to give out, it wants to stall but then it kicks back in. (as my foot is on the throttle). I bearly made it to a parking lot and pop the hood too see whats going on, and the car stalls out. The engine seems really hot. I tried to turn it on again and for about 20 sec it stalls again. I waited for about 2 minutes and turn it on, then pop it on first and forced it to get home. As I'm driving it wants to give up and kicks back on monentarly. When I put my hand on the rad cap I can feel the liquid moving, almost like it's boiling. The engine is very hot and cannot touch.

Please help...

CAS.

BTW, the engine is always burning hot to the touch...

EDIT: ...this means that you shouldn't worry If it's the CAS you only need to change it and everything will be roses and peaches again.

Is there a way to diagnose this to confirm it's the cas? Or could it also be the maf?

[MarusGTR]

Get a new one. It's something that always eventually fails so if it's not the problem you'll have made preventive maintenance. Shouldn't cost much.

I doubt it's the MAF since you're having the problem at idle.

When this part is failinig why wouldn't the cas throw a code? It is mechanical but at the same time it has a electronic thing on the cas sending a ecu a signal. Dirty burger and I just went through this on his car and went for codes and nothing. When we heard it could be the cas he brought his down to my place was absolutely seized. Can someone explain to me how the works? I am just trying to gather why something like that wouldn't be measured and throw a code

John if you think its the CAS, you can borrow mine to see if its any better. Just let me know when your free.

Why would stalling at idle eliminate the MAF? My GTST was running like a bag of dirt (at idle and under load). Cleaned resoldered MAF, night a day difference. Running like a champ.

+1 my first thought was the maf also. I had the same symptoms, a new maf cleared it right up. My next guess would be the O2 sensor. Try unplugging it at idle and see if it runs any different.

Thanks for all the help guys. Bellis is coming over tonight to try a few of these to see what will fix it. I will post update if it works, so others with the same symptoms can use this info

[cschepp]

Definitely interested in what the problem is

I'm hoping to god it's the maf or iacv needs to be cleaned. Im praying it's not the turbo.

Because I'd think that the MAF would cause slow response and choppy RPM, not random stalling from a healthy idle. CAS is the first thing that pops to mind with random engine stalls.

[GTRADDICT]

His problem seems to be time related (first few minutes) which means it's probably heat related. This points out to CAS usually. Quick swap will tell.

Does anyone know where to purchase a new cas? (if this is the problem) I saw one on eBay, but it's going for 500 is that the price for them?
