When was the last time you had your PM (Preventive maintenance) check? Did they also checked your fuel filters, Fuel pump, Air cleaner, etc?

Check your engine support

fuel filter and pump has not been checked, engine support visually ok naman. does the quality of fuel something to do with it? or spark plug maybe?

What is your base idle speed? Do you have misfires or MIL on?

[step22]

800-900 rpm. no misfires. anyways based on one mechanic he said clutch disk daw its slipping daw. pero kapapalit lang ng clutch nito wala pa nga 3 months. dapat daw kasi orig ang pinalit. replacement kasi pinalit ko. yun nga kaya po ang dahilan?

[jick.cejoco]

If the symptoms only appeared after the clutch replacement, the most likely cause of the jerking upon take off would be poor friction surface preparation prior to clutch reassembly. The new pressure plate was coated with oil based corossion inhibitor and was not cleaned with a non petroleum based cleaner such as brake parts cleaner or carb cleaner. Or the flywheel surface had oil residue, or the "mechanic's" hands were too dirty and he touched the friction surfaces with them. Your frictions may be slipping from contaminants.
