2000 Chevy Blazer 6 cyl Four Wheel Drive Automatic 190000 miles
my check engine light is on I had my computer checked for codes and it said that my mass air flow sensor, cam shaft sensor and intake manifold pressure sensors were all coding i've changed all of these to no avail. My blazer still idles rough for approximatley the first 20 seconds then the idle is fine. What else be setting these codes off is there a vacum line that would affect these i've visualy checked these and can't find any thing wrong with them also about this time my tach. Quit working.
have the same problem?
