Problem with engine

[S.Top 20V]

Hello frenz,

I have problem with my car engine.
It will jerk/turn off while the car still moving/running when I press the clutch to shift from high gear to low gear and when slow down at trafic light. It happen quite frequent unless if I keep on accelerating the engine. This only happen when I turn on the aircond.
Fyi, I'm using engine Silvertop 20V that fix into toyota AE111.
Appreciate your help/idea on how to solve this problem.

Thank you.

sounds like a problem with the aircond solinoid then, u may just need to adjust the bypass valve of the solinoid to increase the revv to acommodate the airconditioner load. check dat and report back asap sir

bro xtremeleo
for ur info. instead of adjusting the solenoid valve, I make an effort to clean up the ISCV using a carburettor cleaner. Now the engine back to normal condition and have a better idling.

nice to hear dat, ive a 4e dat is also using the iscv, currently my idle flux between 450~750rpm, its been confirmed by ur post dat the problem is created by a dirty iscv, thank you sir. my idle when the aircond unit is switched on is stable, i adjusted the said valve.
