my afr is reading lean at top end of 4th and 5th is my fuel pump on its way out or somthing any ideas?? cheers grant ps it only started after i fitted my decat down pipe it might be a coincedence or is it

 

DP'll lean it out a tad.
MY? And when you say 'lean', where's the 'lean' info coming from?

 

errrrrrrrrrrrrrrrrr, afr dint he say

 

AFR info comes from various angles with wildly interesting info... AFR reading lean from a BRD calibrated LambdaLink is quite a trustworthy bit of kit (assuming the best available is from a narrowband), but other kit could get a bit wierd...
Also, with narrowband, if it's after a hard 'session' the meter reads lean anyway, so can be ignored to a point.
