ok, i replaced my f22a4 with an f22a6 [not for performance reasons or anything... obviously] but for some reason my engine light keeps coming on, any ideas? would the ecu be doing this because its not the same engine i had in there?

 

Go run a search.

 

what exactly should i search for?

 

pull your codes....a small plug under the glove compartment...ground it out with a screwdriver or something and turn your key to the ON position...should blink a certain number of times to tell you why it's on......search for ECU codes or something......just make an effort

 

go pull the code like fizzbob7 said, it should give you 2 number like 41, 50,etc

 

thanx a shitload, will do tomorrow
