Supercharged 2 Posted June 20, 2013 Something's wrong as they should run really clean being supercharged... Does the oil smell of fuel? - if so change it and get the lambda checked out. How quick does it feel?? could just need setting up Clive Attowe in Norwich is a good place to go for diags / tuning etc Quote Share this post Link to post Share on other sites
bradv8 10 Posted June 20, 2013 It's pretty damn flat at the min n stinks of fuel! It's been a project that I've been doing for a while n got all the parts from various people of here n eBay lol will probably get another lamba sensor n give that ago, what's the screw on the back if the throttle body for ? I should really take it to some one like Clive atthowe in Norwich but need it moted to be able to drive it! Quote Share this post Link to post Share on other sites
owen g60 10 Posted June 20, 2013 Does your idle switch engage? This caused mine to clog up the emissions tester on my last mot. They tried setting it up but was pointless with idle switch not engaging. Quote Share this post Link to post Share on other sites
Graphite 0 Posted June 20, 2013 Ensure the lambda probe is connected to an earth and make sure it is a good one. It should be earthed to the engine mount. Quote Share this post Link to post Share on other sites
