I'm a newbie with this 2LTE prado and honestly a have no idea on what to repair now. It started when smoke came out of exhaust everytime I start it during morning and even in traffic. Pag medyo paakyat pa and daan mahina ang batak. so nagdecided na ako magchange oil and at the same time replaced the air filter. A bit of improvement with the smoke but still it was heavy. Pinacalibrate at palit ng 4 nozzles brand new ones as it was already have to be replaced. After having it changed I gave it a few spins and what I noticed is that theres not enough power or acceleration, humina pa lalo. Tinakbo ko sa highway hanggang 60km/hr lang ang kaya itakbo. BTW smoke is still there. CAn someone please help me with this? Thank you.
