Hi

hope someone can help or give a little advice, I'm having some running problems with my VG30E i'll try and discribe them

it won't really idle and wont rev with out stalling, you can however if your carefull get the rev up slowly to a point then it pulses the rpm (kind of like what a rev limiter would do)

I ran the diag on the ecu and came up with these details

red green

1 2 airflow meter

1 3 Cylinder head temperature sensor

2 1 Ignition Signal

2 3 Idle Switch

3 1 Air conditioner

4 1 Check fuel temperature circuit

 

Any idea's advice is greatfull

 

thanks

kin ell not to many error codes then :eek:

I think it may be better to reset the ECU and make sure. Some of those codes could be old.

the battery has been off for days, thought that would have cleared the codes?

Yes it would have done :(

Oh :headvswal

Any idea's then? where i should start, i can't see them all being worng (i hope)

Quite a few sensors are showing error codes there.

Does it have a chip?

it's still factory mate nothing changed

fogot to put in last post,

just found a fsm for it so i can test the sensors and wiring now :)

I'd look into the AFM error code first, as that would introduce a rev lmit at around 2.5k rpm if there's problems.

 

Check the Coneection is secure to the MAF, and check the voltage.

cool i have another afm but it's of a 300C still vg30e) might try that on it and see if it makes a difference i know it may run a little lean with it but i hope it will be ok just to test

the maf don't look to great tbh

thanks for the point's somewhere to start now :)
