DIY MAF Sensor Cleaning for GA16DE/ DNE

Taken from scph forum hope this would help:

I know a lot of people have had problems with

1. Rough/bad unstable Idle
2. setting timing
3. Setting ECU into timing mode
4. Cleaning and identifying : IACV, MAF, TPS, throttle
5. Setting Base idle and timing
6. Lack of power
7. rough power delivery
8. Hesitation and rough accelaration
9. Fluctuating Idle
10. Engine Dies when A/C is turned off
11. idle drops when turning or doing 3 point turns or when decelerating (slowing down and when in gear putting gear into Nuetral)
12. Engine Dies at any point due added load

This Write-up Most likely will Solve your idle / timing issues as long as everything else in your car is in good working order and their are no other issues like Electrical and Mechanical gremlins

Tools/cleaners you will Need:
1. Carb Cleaner

10, 12 mm sockets and combination wreches, including extensions and ratchets

flathead and philips screwdrivers

large adjustable wrench

pliers and longnose type as well

rags or toilet paper, shop towels or any cloth/papertowel

1st off remove the C-clip securing the MAF pigtail to the MAF assembly

remove the clips that hold the top part of the factory airbox to access the air filter and loosen the 10mm bolt securing the MAF to the airtube, dont forget there are also 2 more 10mm bolts securing the top half to the resonator box connected to the airtube


Here is the MAF assembly connected to the top half of the airbox


look through the hole of within the MAF assembly



you will notice within the small hole, will be the Hotwire Sensors for the MAF - these get dirty overtime - from a distance of about 6 inches away spray some carb cleaner, be careful not to be too close as not to damage the hotwire sensors - keep the carb cleaner tube at a distance when spraying but close enough just to remove dirt and grime on the hotwire sensors


WARNING: use some electrical tape and wrap around the straw of the CARB Cleaner to prevent the straw/tube from flying inside the intake manifold

Next Step - loosen the 10mm bolt that holds the clamp of the Airtube connecting it to the throttle body, open the throttle plate and spray some carb cleaner in there, let it soak
