Mass air flow sensor

system is MAP see diagram what was code? do not replace until we cofer

I don't get a code. History - vehicle runs rough at idle once up to normal operating temps. I have replace spark plugs and cleaned fuel injectors. Parts man at GM shop said his problem was MAF Sensor and cleaning it fixed his problem; I thought I'd try to clean mine but the Hanes Manual doesn't show the location. Is the MAF a part of the MAP?

Thats why he is in Parts NO MAF and no cleaning of MAP. Many things will cause problem have a diagnostic scan done see what results are. post and will advise

Finally got the Bravda into the shop. Nothing showed on diagnostic scan. The only thing left to cause the vibration was motor mounts so I had them changed. They were not broken but worn enough to cause the noticeable vibration at an idle. All is well with the vehicle now.

Great news
