ran the code tester it came back with running to lean in cylinder one and missfire on cylinder one the guy at autozone told me i need a new mass flow sensor what say you guys out there????


thanks for amy help:)
 
Well I would assume the misfire would be a coil or a plug. The lean on bank one might be related to the misfire, or it could be a o2 sensor going bad. I would get that misfire taken care of first. Then unhook the battery for 5 or 10 minutes to clear the codes. Then see if the lean code comes back.

So to sum it up change your spark plug first, if it still misses change the coil out.

You could also try cleaning the mass air sensor and running some seafoam through the air intake or vac line as well.

check engine light back on replaced sparkplug uggggggg
 
If it still feels like it is missing I would check into changing that coil out, and reseting the code again. A intemitent miss could cause the check light to come on after a couple days.
