Q: Mass Air flow sensor

asked by on

i changed the mass air flow sensor in my van and when i plug it in the engine bogs down and dies when i unplug it it idles fine
My car has an automatic transmission.

If the engine runs poorly with the mass air flow sensor plugged in, this suggests it may be dirty or not working properly. I would recommend cleaning it first and plugging it back in. If this does not solve the problem, you may need to replace it.
