Need your expert help please. I have an Isuzu Bighorn (converted) 2001. Nag mimiss ung gas ko. pag tapak ko sa gas nag rerev lng sya, tapos tatapakan ko ulit gagana pero medyo humaharurot. Uma andar pa naman sya kaso nag woworry ako na bka lalong lumala. as of now nka check engine sya (throttle problem) not sure kung connected sya dito. Pinacheck ko sya sa Rapide dati tapos related daw sa throttle position sensor ung error code so nilinis nya ung TPS pero after 4 months bumalik ulit ung ilaw sa check engine. previous to that incident (check engine light on) pinapaltan ko sya dati ng diesel injection (not sure din kung connected) kc parang humina ung makina and nanginginig sya. Sana po maka pag refer kayo ng mechaniko na magaling and expert dito at price efficient din and if you can give an advise it will be greatly appreciated. If you ca recommend a shop sana po sana around rizal or metro manila area. thank you in advance.
