Wont Rev Past 2000Rpm. And Will Stall After 5-10Min

[r33cruiser]

Hey guys noticed this after a drive. If i came to a stop and was idling for a few mins the car would gently die. I was able to restart it straight away no worries.

Now it wont rev past 2000rpm, when you add more throttle it just pops as if it only had 2 running cylinders.

Eventually it will stall after idling for 5-10min.

Its a built engine with cams, gt35r, Pfc and all accompanying mods.

As of now it is undriveable and is just sitting in the garage

Ideas?

I am led to believe that this is a C.A.S issue?

Sounds like either a Dead AFM or a cooler pipe has come off

Afm has been checked by my mechanic, voltage and wiring is fine.

Will definitely go over my cooler piping again. I am only running 12psi-still on run in tune so I dont think a join has popped off. I will investigate my plumbing further tomorrow.

This happened to me for no reason all I did was put on my coil pack cover and started the car and idling like on 2 cylinders and would pop when you rev it couldnt figure it what it was and then after 30min started it again and drove up and down and it was back to normal still puzzled with what it could have been.

plug a consult cable in and check the fault codes for the afm, I'm sure it is that.

Consult doesnt work with aftermarket ECU's

Wrong thread lol

Could still be AFM. Sounds intermittent, so when the car does due - check the sensor read out on the hand controller. That'll clear or confirm the AFM.

Thought I would give you guys an update. Finally got some time to go over it today.

Due to my r34 cams I have had to use an r34 cas. I took off the plastic cover of the cas exposing the bronze disc inside. The car started and revved freely.

It appears that it was full of dust and that was restricting it.....well maybe.

Its revving fine now, it idles etc so lets hope it stays that way

Interesting... Ive just had a rb26 engine fully built, runnin-in atm.

I too am using R34 cams and R34 cas, engine is R32. Will keep this in mind........
