Hard starting and rough idle when engine is cold. Pag uminit na ok n sya. Di naman umiilaw ang CEL(check engine light). Please help!

Tune up, change filters and plugs. If all fails, fuel pump problem na yan.

Hi shibby75! Tnx sa reply. Kakapalit ko lang ng OEM fuel pump & spark plugs. Nagpalit na din ako ng fuel filters pero replacement lang.

Did you try resetting the ecu? Unplugging the battery overnight?

I did remove the negative terminal for only about 20 minutes. Should i do it overnight? Positive and negative terminals?

Ang the best way to do it is have it scanned kahit wala CEL.

Mileage paps? Hindi ba yan nabaha?

Napalinisan mo na ba air filter mo? Baka madumi ang fuel tank mo, pero kung sabi mo nga kapag mainit na engine nag ok na, baka madumi na ang engine oil mo or oil filter.

Check also your MAF sensor and throttle body lalo na kung aftermarket ang gamit mo na airfilter.

Mileage is 115k. Di sya nabaha. I'll have it scanned na din in canpro para sure. Tnx sa help niyo mga paps!

Masyado na mataas paps, clean your MAF and air cleaner.

Unscrew the MAF. Spray with electric contact cleaner. Dry. Install. Just handle it carefully and spray from a good distance (baka matalsikan yung mata mo).
