running lean
 

Hi guy`s, a little help needed, at interpro on sunday they put my car on the rollers and stoped halfway through the run saying the car was running to lean [so gutted] :( ,they said it wasent putting anymore fuel through when it was on boost ?, has anyone got any ideas of what the prob could be. some advice would be great.

Cheers

Matt

what year is car? uk or import?

Mafs on late classic uk cars are renound for causing this. Probably why pslewis can get 38 mpg!

the car is a 92 wrx.not sure how old maf is,how do i check if it is still working ok.
