Jerking Problem With My 1996 Satria 1.6gli

[paultantk]

I'm driving a 1996 satria 1.6gli. running standard 4g92p engine. only mods are the usual extractor and mufflers mods and a K&N drop in filter with CAI.

today i've been experiencing jerking problems during acceleration. this happens during light and medium acceleration. never try hard acceleration. the car like stalls a while, jerks one time and then everything goes back to normal. the engine check light also turns on a while during stand stills at traffic lights but it usually goes off when i tap the accelerator.

anyone know what the problem is?

i've felt this kinda jerking before on my nissan sunny but that was a carburettor problem, and felt it another time in a taxi that was running out of fuel.

check your throttle body, might need cleaning since you make CAI dust getting in faster...very common problem if your CAI airflow design not good...

Just changed one of the gears in the throttle body assembly 2 months ago, one of the gigi patah liao causing unstable idling. That time clean already, so fast dirty again? I'll check tomorrow.

Possible...update me after you check.

I don think throttle body has got anything to with jerking during accleration.

Check on ignition and fueling.

check also your knock sensor. the sensor that detects knocking. the way to check is to do a MUT check. since check engine light appeared, it would have logged the error code in the ECU. it will show in the MUT.

check the spark plug cables, if it comes loose there will be jerking.

Fixed my problem this morning. Mech checked the error codes, 3 appeared. Air Flow Sensor, Barometric Pressure Sensor (something liadat) and somethign to do with the throttle body. Just replaced the Air Flow Sensor (which the barometric thing is actually a chip inside) and all 3 error codes disappeared. Engine check light stopped showing and no more jerking.
