1G Stalling when hot

[jenjen]

Hi guys,

I have recently changed the radiator, the Iac, the Oxygen Sensor, the fuel filter & the darn car still stalls when idoling in really hot temperatures.

I think next it will be the MAF or the ECU, but I'm worried that won't help the problem. Other than that she runs great, but doesn't like heat.

What do you guys think it is, because I'm running out of options and miss driving my car.

Please help!
Sincerely
Jennifer

Yup, could be. That would cause a bad vacuum leak.

 

[jenjen]

cool, so tomorrow I will check that...thanks you so very much
I appreiaten your help tremendously

im thinking it could be a bad maf, the maf is the only thing that really has an affect on fuel and if it bogs down goes super rich and then dies then id say its either a bad MAF or a bad ecu. vacuum leak would result in a high idle i think not low.

my other guess was a bad Cat but i guess you dont have one anymore

the Igniter, MPI relay, CAS or EGR wouldent cause this problem and thr mpi relay is power to the car. the car would just shut off like when you pull the key out if it was a problem with this relay. the igniter and cas are spark relatedwhich again doesnt seem to be the problem

id say get junk yard MAF and give it a shot... theres alot of NT 1gs out here so if you cant find one let me know and ill see if i can get you one.

Here's a little input on the Brake Booster :

When you're idling and press in the brake, do you hear a Hissing noise by your foot? Mine does that, and it causes the car to idle a little rougher than with the brake released. Also, go ahead and check the hose, and the nipple from the Intake manifold that the hose is connected to.

Next, go ahead and make a boost-leak tester. I know you're N/T... but put it on your Intake Manifold and put a little air through the system, see if you can find ANY leaks. For all you know, it could be a bad vaccum leak from expanding hoses when everything get's hot. This should help you locate a leak.

It simply sounds like a bad leak to me, but go ahead and check the wiring on your MAF plug. if it looks rough, cut it and re-wire it. Mine did that as well and I had to rewire it and cut out the bad spots in order for my car to run properly.

Take care of the cheap things first. Throw a ton of money only after you've eliminated all of the simple issues.

When you say that it bogs down and dies "when the engine gets really hot" do you mean that it's overheating?

Also, usually when your ECU or MAS goes bad, you'll get a CEL... but then again, these are DSM's after all. Try to get a code read with a voltmeter and check all of your vacuum lines for tears, wear, or even discoloration. Replace any that look bad and see if that by chance fixes your problem.

thanks everyone , I will definately tell my mechanic to check the break booster for a vacumm leaks and have the MAF wires checked at the same time.

also, just a reminder, like mentioned above a friend told me that he swears its a defective overflow sensor
Is this possible?

 

[pj91gsx]

you know my vote is yes but what does everyone else that read the thread think??

i say no to it being the throttle body shaft seals and biss idle screw leaking, the reason i say that is because its nonturbo. It will lean out the mixture but not much i know people that hack the lower honey comb out on a nonturbo to get better gas mileage with no problems, just idles a little funny, because its leaner at idle but it doesnt hurt anything at idle.

Hang in there. It's going to require patience and research to find it. I'm sure it can be fixed. I'll review the thread again later and see if I can help you come up with anything. The ISC should have been tested, and if tested bad, then replaced. Your mechanic should have tested it, not just replaced it.

I'm having the same problem. I recently got my 92 TSi back from a shop where i had a blown headgasket fixed. All new manifolds, head was brought to a machine shop, resurfaced, and a full coolant test done. Car ran fine for them.
A day later, Im driving, no problems for about 20 minutes, but then I start to notice the engine is overheating. first symptom being lowered throttle response, slower idle, and eventually it just stalls out. Car struggles to turn back over, until I let it cool off. I'm a little frustrated, because all that repairing cost me over $1100.

Details
92' Talon TSi
4g63 6 bolt
16g (without a functioning wastegate actuator, getting that replaced) so not pushing any boost atm
Greddy BoV
Greddy boost controller
Greddy turbotimer
SAFC

Any help is appreciated here. I love my car to death, but she's breaking my balls.

Hi Everyone,

I have a eagle talon 1g NT. I have changed almost all I can think of on this car hoping it will stop the stalling problem, but the darn car still wants to stall.

It happens when the car is either driving for a long while, or when it's stoped at a light for a long time. The idle starts to drop and the car stalls & dies. This also happens when you break really hard.

I have changed:
Radiator
coolant system
ISC motor
Iac
Oxygen Sensor
Spark plugs
Alternater
Put in new sterio with 4 new speakers
remote starter

I am at my wits end, just lost my job and don't have the money to keep changing pieces.

Does anyone have a clue what can be causing this anoying problem before I pull my hair out from the roots.

I don't know what else to do and I'm really starting to give up

Is there anyone out there that can truly help me. I'm begging you all

Sincerely
Jennifer

Hi, I remember seeing you post about this problem some time ago, I am sorry to see this is still giving your trouble. I would look at the remote starter install. I would also open the ecu and see if the caps are leaking. I have a 1g n/t 5 speed ecu you can have if you need it. There are alot of things it could be. What exactly happens when it stalls? Does it sputter and die or just die?

 

[jenjen]

HI There,

Thanks so much for replying to my thread. I truly appreciate it. Thanks so much for offering your ECU. That's really sweet of you. I have thought that maybe the Biss screw needs to be changed to a new one, but because my car is NT i'm not sure if this exists.

The car doesn't just die, it stutters then dies everytime it happens

What's your thoughts

Jennifer

Boost leak!!!

i'd say its prob a vacuum leak, bad injector, or ECU

 

[jenjen]

my mechanic just tested the boost and there are no leaks

 

[colbyc]

Its non turbo.

Are you throwing any cel's?

 

[Develop247]

Boost leak!!!

i'd say its prob a vacuum leak, bad injector, or ECU

x2 from my experience with my honda it did the same. sorry to say, i never fixed it. so whomever stole my car and has my motor; i hope they have the same problem!!! but anyway. i believe it would be a vacuum problem. do you have a vacuum tester? they are relatively cheap. about $20us at Autozone. It could also be a bad injector, clogged fuel filter, bad emissions components, or incorrectly gaped spark plugs.

check plugs, wires first, then, replace your fuel filter. They should be done annually or every 30k miles.

 

[jenjen]

Fuel Filter was changed to new along with new spark plugs and all vacumm leaks seem to be ok.

Were thinking maybe the Biss screw but I 'm not sure if I have one because it's NT

 

[Develop247]

are you using anything to tune it with? give it a carb cleaner bath through the intake side.

I was just thinking about the offer you gave me on having the 1g NT ECU. That would be great, but how would you ship it here? I'm in Montreal

Btw, my car is an automatic, will the ECU still work because you mentioned it was for a 5 speed

HI everyone,

I know my previous problem with my car in regards to it wanting to stall every time I come to a stop, usually happens when its warn out and it's driven for awhile, but I went to put gas in the car the other night and the car was fine afterwards. The next day I needed to run errands and not even 2 min on the road the car started studdering and wanting to stall. When I pumped the gas it was moving and when it finally kicked in, the whole car started to vibrate, like it was over working. It's Winter here and cold, so there should be no excuse.

Can someone please help me?
Sincerely
Jennifer
