Hesitation while driving?

[Jaymz88]

Hey guys, its been awhile since my last post. Still check the site everydays though !!

I own a 2003 ecotec with ~117 km on it and have no problems in the past 2 years (Minus wheel sensor and broken strut spring). Anyways, since about 2 weeks ago, while driving on the highway, driving at about 1500 RPM and lightly feather the throttle, the car will occasionally buck or hesitate, whatever you wanna call it, while trying to accelerate.

Diagnosis from the aleromod gurus please

Thanks in advance

Is your engine light on?

[Jaymz88]

Yes it came on a little after this started. You think its just a dirty filter, that would be great lol

Ever change the fuel filter?

Get autozone or somewhere to scan the code and check what the light is coming on for... if it's a misfire see how your fuel filter and spark plugs look for starters.

^they only go bad if they throw a code, not worth the money otherwise.
