Code Help
When i check out my codes that my ECM is throwing it comes up with code 33 and 34.
its a 1986 camaro w/ a 2.8
how can ut be giving me these codes
33. High voltage (low vacuum) at mass air flow sensor (or MAP sensor)
34. Low voltage (high vacuum) at mass air flow sensor (or MAP sensor)
just makes no sense
thanks

could be trying to tell u that the actual MAF is bad, that or ur not getting any power to it....did u get a code 12 in conjunction with ur codes? if not, then ur ECM might be screwed and i wouldn't trust any code that it sent u.
