R33 Gtr Stalling Issue

[SinnyGTR]

Hi guys.

Im sure this question has been asked a million times but I'm new here and also a new GTR owner.

My question is basically whats wrong with my GTR?

basically when I start it its fine but once I start driving it seems to be losing power or serging the rpm drops down to 0 and the car stalls. it seems to be getting worse and worse each time I drive it. I have only noticed it today after I pulled out the boost restrictor. I didnt read anywhere that this could be a problem.

Any help you guys can give me will be greatly appreciated.

just look at the title of almost every single response lol. somewhere in there, with some further diagnosis of your own, lies your answer.

search function at the top right hand corner is your friend

Check your vacuum hoses and cooler plumbing for leaks. Are u making any boost?

[SinnyGTR]

everything seems to be working fine.

It was a pretty hot day today and the car doesnt seem to play up unless its hot or ive been driving a bit.

I read the other topics but still struggling to work out the problem as i am not a mechanic or very familiar with this or any turbocharged cars.

scratch that last post.

it seems to play up even when its cold. one of the small hoses near the air box seems to keep popping off when i drive the car, it has been doing it for a while but this seems to only slightly affect the cars performance not like how it is driving at the moment. I will get sore clips to hold it in place today and see how it goes. im sure there must still be something else wrong.

Small Hoses? pic would help

This could be 1 of the lines going to your boost controller either way if its connected to an intercooler pipe then this coming off is your problem, can you hear air rushing out of the hole on idle?

[SinnyGTR]

Doesnt seem to be leaking air.

it is stuttering real bad now. only seems to do it at low rpm because when I open it up it plays up for a little but as soon as the rpms high enough if seems to drive fine.... is there an easy way of testing the afm if thats the problem or should i look for somethin else?

Its strange because some days it seems to run fine and other times its junk

Sounds like typical AFM issues.

They are 10+ years old, so this comes as little surprise.

Definitely sounds like an afm issue, do a search for faults relating to that. Have you tried cleaning the hotwire? Could it be a bad solder connection inside on the afm board?
