check emissions light's come on....

[litchy]

Had ecu flashed but light (& spanner) came back on after short period. Think it said it was the air inlet valve thingy (think its the bit that the pipe from the TB goes to)

check emmissions, will be down to the lambor sensors, have you got a de cat at all?

my check emissions came on other week and it was just due to a bad batch of fuel cause put some new in and its been fine since. ive had mine decatted for 2 years and this was the first time the light came on.

You mean the mass air flow sensor (MAF)?

That could cause the air fuel ratio to be out if it's letting too much/not enough air in which would then cause the lambda sensor to give a strange reading, throwing up the error
