Stalling Issues In Drive - Please Help

[GMan]

Hi everyone,

A very weird problem had just occured. i drive a r34 gt-t in automatic/tiptronic. i was driving down a slope when i started to notice that my car started spluttering. it was raining and i thought that some water had gotten into my intake so i just hit the accelerator harder. when i did that it spluttered more and started to stall. i pulled over and put it into neutral and just started to rev it out. put it back into drive and it just stalled. i tested out every gear and put it into reverse and it was fine. put it back into drive and it stalled again. gave it some revs in neutral and chucked it into drive and then stalled again.

all this resulted in me waiting 1.5 hours for a tow truck and then got charged $80 for a 5min ride

its at hills motorsports now and they are going to look at it tomorrow. hopefully it wont be too expensive. this is my 2nd incident regarding the rain....first was a misfiring/cant start issue.

any insight or information would be greatly appreciated!

cheers!

do you have an aftermarket vent to atmosphere BOV?

One would think its electrical, if it only occurs in the rain. Have you changed anything recently? Do you have a vented bonnet? CAI? Try checking error codes.

if it's rain related, it must be water getting in to something.

Vented Bonnet = spark plug swimming pool

fully sick pod filter in front bar = wet muff .. sorry.. I mean wet MAF.

being auto, and you said it works ok in nuetral and reverse, my guess would be the isolator/safety switch that wont let you start the car in gear?

Im no expert, but its just an idea. maybe its got a loose connection or exposed wire somewhere

nope...bov in standard position

no vented bonnet. the mechanics seem to think thats its electrical but still not sure yet. no cai.

im not so sure if its just a coincidence with the rain that my car always seems to break down on. but yea last time i had the spark plug swimming pool incident regarding it so no vented bonnet. also my pod is at the standard position where my airbox use to be.

no idea.. its not that it wont start in gear..u cant start autos in gear.. it just keeps stalling in gear thats all except for reverse which is weird.

thanks everyone

i just heard back from the mechanics. he plugged the scanner on and it didnt show up with an error code. he says that its either mechanical or theres a problem with the ecu.

just wondering if anyone else has had this problem before??

[GMan]

finally got a word back today after a whole week of it sitting in storage. he had told me that the computer was not giving out any power. power was going in but not coming out so he sent it away to get it tested.

does this sound right to anyone?

if the computer didnt work then the car wouldnt start right?

don't get it repaired.

buy another stock auto ecu from wreckers or these forums.

cost a fraction of repair..

but you're right.

the ecu controlls everything including the auto box.

so if it was faulty, it wouldn't run at all.

I don't know muuch about auto's, but there must be something that controls idle when in gear.

just like when the air con is on etc..

yea just got word back from mechanics couple days ago.

the 1,2 shift valve solenoid has failed. this means that when drive is selected, 1st and 2nd gear both comes on at the same time. now im just patiently waiting for the part to come in. im a little annoyed as he promised to have my car ready 2 days ago but he had ordered the wrong part for my car.
