Hi Im David, if you unplug the maf, do you get throttle response?

Customer: replied 8 months ago.
I do
Expert:  david craig replied 8 months ago.

ok. then you need to check the wiring to the maf before condemning it. look for any obvious signs of wiring damage. check the connector and make sure the pins are in tact and not corroded. i will provide you with a print if you'd like
