Any help is appreciated...code said i needed 1) rear o2 sensor. well i had them put both in (had 2 new front ones put in 30 days before. after that, code said front o2 sensor so bought another new front & had the shop install it...now code said mass air flow sensor, so bought used one and again had shop install. still engine check light comes on. code said air flow sensor still. had the shop put new air & fuel filters in...same results. Any suggestion? car runs fine. thanks
 
That used mass air might of had the same problem as the old one -- it was dirty. Did they clean the sensor before installing it?
 
Disconnect your battery for a minute then reconnect, this will have the effect of resetting your computer. If the light comes back on again stop at one of the chain stores and have them print out for you the codes and get back to us with the code # so we can offer some more direct advice. By the way the stores should do it for free also.
