hi bud that's pluged in may have to put more petrol in as I don't know how much is in there and its still up in the air got to be something simple

Where to start? It starts then dies.. It wont run even if you try adjust the engine rpm with the pedal? Have you changed injectors?

have you got the fuel regulator mixed up with the fuel damper ..both on plenum and can be confusing

eerm going to say don't know is the regulator bigger than the damper just trying to think all I can do is change them over

is the maf you're old one or a new one? can you get a spare to try... in case it's the connector or the loom...

 

and have you cleaned the connectors?

hi yea its the old one iv cleaned the plug when I replug the maf it just cut out took the plug off started high revs but ran on her own steam iv just seen how much thay are but I think needs must

Nope your Maf is doing its job ... unpluging it only indicates the Problem is in another place and on your engine being a NA

not meny places so i would start checking all the Pipes

 

Idle Control valve all 4 pipes

Air Intake Both sides

PVC pipes

 

and just for testing Block off the 2 vac lines on Throttle bodys

and the side and balance pipes
