Engine turn off

[cypress8]

Hi Sifus,

Just wanted to know why my car engine turn off (stall) by itself when cruising at the normal speed (mostly second gear...). It happens once in a while. I'm using a 4G63T (EII) with a stock bypass valve. No other mods at the moment.

Please advise. Thank you very much. :(

check your air flow sensor...i guess...correct me if i'm wrong.

check your wiring and do diagnostics. :)

I suspect wiring also. I had the problem with my old volvo before, it was due to loose wiring near the ignition switch.

All sifus,

Thanks for the advise. Will try to check the items that you guys mentioned. Between, what to check for the air flow sensor? I'm sorry lar bro, still new to this turbo cars thingy.

I found that it only happen when I switch on the air cond. Does it mean that there's something to do with the air cond timing? Before switch on the air cond, the RPM is around 1000 and after switch on the air cond, it drops to 900++ (is that normal?).

regards.

ohh, the air cond timing problem is very common for 4g63, there is supposed to be a wire connected to re-adjust the timing for the aircond, perhaps that wire wasn't connected properly.

This is what I suspected. Thanks Danny for the info.

to check the air flow sensor,the simplest thing to do is to find another proven good airflow sensor(From your friend car or else) and swap it with yours.then try driving with it. if still problem check your ISC.

correct me if i'm wrong :)
