Not even a month since I sorted the coil problem when another problem has come up was driving today put my foot down and a restricted performance came up for about one minute once it went the car drove ok stopped at traffic lights put my foot down to move off message again ran a scan which came up with system too lean bank 1 checked fuel trims this is what I got
at idle bank1 short term 25% long term 19.5 bank 2 short term 25% longterm 19.5 with the throttle held at 2k rpm readings were bank1 short term21.9% longterm 47% bank2 short term 18.8% long term 0% any ideas

 

A vacuum leak perhaps?

 

well yesterday I went to have a look at my air flow meter and noticed the pvc hose was completly disconnected from the intake pipe I think it might have been loose and my arm may have brushed against it completly disconnecting it as before the restricted performance message was intermittent but then the message was there all the time I reconnected it and cleared the codes the message has not come back and no mil light only time will tell as my mileage is pretty low as I have a company vehicle

 

Good job I think you found the problem.

Sometimes it is just a small thing and in your case nothing was actually wrong with the car. Just needed a hose reconnected.

yes but I am still wondering it only showed bank 1 as running lean and not bank 2 aswell

 

After a few decent runs see what the trims are in case you've another problem.

 

yes I have heard that it can take up to 10 miles for the long term fuel trims show acurate readings I will take it for a good run after christmas and check the fuel trims after the run

 

After a fuelling-related repair you can force a relearn by a hard reset.

 

ok will give that a go before I drive it again
