Hi, ask lang sana ako ng opinion if it is still worth to keep my 2000 exalta STA?

Nakuha ko kasi ito sa brother ko.

After I got the car 6 weeks ago, pinagawa ko na ung power steering hose. Then I had this idling problem which rapide diagnosed as a problem with the throttle and airflow sensor which should cost me alot of money.

So pinagawa ko nalang ito sa talyer sa may quirino, pinalinis ko nalang yung throttle and nag palit ng air filter.

Question lang sa nissan owners, madami ba talagang problema yung exalta? Im wondering lang kasi kung worth to keep, or will it just give me more headaches?

Thanks.
