Maintenance
What could be exactly wrong with my 2003
Mazda 6 2.3 4 cyclinder it's been rough
idling, stalling alot mainly on cold morning . I
already replaced computer, camshaft sensor
and a few people says it's could be IAC or
purge valve I brought one and install it but
no difference to vehicle so I return it and put
old one back on can u give me a suggestion
to try?
