Hello and welcome to the LOC.

1st question, is the servicing up to date?

2nd question, are there any warning lights on?

A possible cause could be the throttle body needs cleaning,cheap and fairly easy to do but there are lots of other causes.

well it was recently acquired the servicing is is not up to date #1,the vehicle have no warning lights #2 but you could be correct about the throttle body because i took of the air box and looked in the throttle body and it was really black!!!

I'm about to change the spark plugs air filter and clean the throttle body but i had already change the oil 2days ago with some 10w/30 fully synthetic oil, what type of plugs would you guys recommend for the 1gfe?

[lexusis200x2000]

Fuel filter.

Fuel filter.

the fuel filter is in the engine bay or in tank?

[ColinBarber]

auto or manual transmission?

The fuel filter is in the tank.

I would first change the air filter, clean the throttle body, check the plugs are correct and maybe correctly adjust the TPS (throttle position sensor)
