EE90 engine tuning

[ckl7480]

Hi All Sifu & Masters,

Recently i just overhaul my ride due to engine oil always leak,i expect after overhaul the problem is solve. Now the leak is solve but engine performances is worse worse than before.

Initially, my ride 1.3EE90 performances is quite ok, underpower is no so much. Now underpower is very bad. I dunno how to fix it. I already send to workshop (Fxxk) to repair but also can't be done.

Even i go another workshop to adjust the firing timing, clean the cabourtar, adjust the idle speed. But the performances still very bad. Very underpower before that is ok also can racing even 1.3only.

Any sifu or masters got this kind experinces , please help me!!!

i think when they do grinding valve they do not do it properly so compression loose. the engine will lost power.

you also can check the distributor timing. adjust to high timing but not too high because can cause knocking.

other thing is vacum "manual sensor". check any vacum hose properly because sometime mechanic not fix it properly.

You are make sense to me, they actual grinding my valve. Due to initial they claim the engine vibrate is there. so they grinding the valve. Now my fuel consumption also high. They are really Sxxk!!!!

I think just let it like this. Cause my spend a lot money to overhaul my ride. Now no money liao.
also they are old liao. i will buy another car after i got money. and no more toyota liao. Maybe go to mitsubishi lancer 2.0GT. Quite fun car
