Pants 0 Posted September 9, 2006 Report Share Posted September 9, 2006 is the lambda reading through 2nd gear, does this seem way to rich for a non turbod variety.Would a "chip" cause this over fueling. Where can I locate the ECU to see if a pervious owner has messed with it?Cheers. Link to post Share on other sites

The_0ne 0 Posted September 9, 2006 Report Share Posted September 9, 2006 Looks like your cars running really rich, could be a dodgy temp sensor, only about £15 to replace mate.If your temp sensor is fooked it runs in safe mode and will drink the juice! Link to post Share on other sites

Pants 0 Posted September 10, 2006 Author Report Share Posted September 10, 2006 Has a play with temp sensor as suggested. It's runs the same under load as before, the only difference is the ilde smoothed out a bit and was a bit richer. Idle was really nice with the temp sensor pulled out.It's worth noting tho that when the lambda is trimming the fuel it runs at 1 lambda spot on, but if you floor it too much or the revs pick up too much it just chucks fuel in. To the extent you see black smoke sometimes. I always thought it was the rings wearing, because it's on 170K miles, but it seems it's just over fueling.I tried cruising today at a steady 60 / 70 / 80... etc.. and it uses a stead 0.90 lambda or 13.23 afr. Ouch. But if it's around 200bhp running like this, imagine if I get the thing property advanced and fueled. :eek: Should see a nice increase! Going to try to locate the ECU and take a look in there.
