Hi guys,
My car is having performance issues. I always fill 98 octane fuel. I have to press the peddle down hard to get upto 60 k/hr . Looks like engine is taking too much power to move the car. I have checked air pressure.
Tyre are brand new
Recently topped engine oil
Coolant is full
No error codes shown at all.

I suspect will it be spark plugs ? . Is there a way to find out ?

Any suggestion would be appreciated. Thanks in advance.

coil packs? .... depends if it's missing on acceleration................ OR if your just driving on really hot day, it's probably just knocking like crazy (engine wise). If it's heat try a Mace Manifold Spacer..... they help a tad

You never said it was missing.... does it miss while in neutral(No load...)?

Coil packs(As mentioned..), Injectors, Plugs, Slipping torque convertor, Gearbox oil low(auto)... pcv/vacum leak, Knock sensor, TPS... would be the tings I would look at first.

Good luck.
