H Im David, thanks for visiting the site unplug the maf and try starting it if you think thats it

Customer: replied 1 month ago.
the sensor or the entire maf? I also saw white smoke coming from the hose that connects
Expert:  david craig replied 1 month ago.

unplug the sensor

Customer: replied 1 month ago.
okay so if that does work, what do you think the next step would be?
Expert:  david craig replied 1 month ago.

it probably wont work, you dont have a maf code. clean the sensor anyway. plus you need a vent control shutoff valve. also with the engine running, remove the oil filler cap and put your hand over the hole. tell me if you feel suction

Customer: replied 1 month ago.
No, I do not feel anything
Expert:  david craig replied 1 month ago.

ok. clean the maf, clean the throttle plate and do a backpressure test to check forr clogged cats
