Title: bit of an overfuelling issue....
Post by: vwmk3jon on February 17, 2015, 05:46:25 PM
seriously on a mission to sort my issues out...

anyhoo, car seems to run ok (well it did before we fubared the turbo!) but it has been overfuelling. plugs were sooty as hell and lambdas been swapped although i dont 100% trust it. its got a PPP map in. exhaust tip always seems to get slightly black too after a week or so.

Lambda makes no difference on full-throttle, unplug it if you're not sure and see if that alters things.

Check your boost switch isn't activating all the time and run through the G40 Digifant diagnostic guide on here.

not really full throttle andy. its more when im pottering along and i take my foot off the throttle and put it back on again.

im being blonde... how would i check that? ill check the wiring to make sure its not shorting etc.
