how about plug cable?

 

[faruck]

cable plug for sure..

 

[nasrulyusof]

My engine is standard stock, i use original evo 4 plug cable, i also think my cable plug maybe rosak, and i try to use my friend evo 4 plug cable, but still got same problem...

 

[faruck]

ECU confirm ok bro?

 

[MiNiFans]

Wondering if what brand of coil system do you guys usually change? MSD? Supetech?

everything i try to change into my engine with my friend engine parts. his car is running condition. the parts i borrow from my friend and try to install into my engine is : airflow sensor, fuel ray, fuel regulator, injector, throttle body, plug cable, coil plug, fuel pump, crank sensor and ECU. For info, i can ram my engine from 1000rpm to 9000rpm without semput if not bergerak, if tarik pickup, my engine will semput-semput. I dont think my fuel filter got problem. but one thing i see at my car is, my rpm kadang-kandang stay at 1000rpm and kadang kadang at 1500rpm (idling time) after tarik pickup. not like throttle body rosak (rpm like high cam)

check any vaccum/boost leak at all rubber hose and piping....

manatau if some vaccum hose loose/crack around the throttle body

 

[nasrulyusof]

normal boost for my engione is 0.6 bar. IF got leakage at some hose, piping or etc the boost reading will go higher. But for this problem my boost reading is normal.

u sure the 2jz fuel pump is sufficient enough?
