The 2.0 liter turbo charged engine is great overall (great gas mileage, and great power), but my engine light came on and I now have mis-firing from the engine when first started, and sometimes when idling. I have changed the spark plugs with NGK platinum plugs. Any ideas?

hey what's up ,as per your mis-fire issue ,u will need to read codes from system ,but anyways u may have a direct ignition cassette fault ,that is the part that sit on top of the spark plugs ,so if the codes u read r p1334,p1312 or p0340,then that is related to your DI CASSETTE ,if non of those code present then u will need to get injector flushed or clean ,those r the only 2 issues for mis-firing with that car
