sory about saying dodgey but it gets peoples attention.

right, a member on here called The Witt has got a problem with his engine managent. its a Punto Mk2.

this is what he knows-

Thought it was a faulty lambda to start with so replaced both of them but Im still getting error codes.

Its the 1st sensor that is throwing up the codes so that rules out an expensive replacement cat.
Doesn't sound like its blowing anywhere so think I can rule out a leak in the exhaust, after that I'm stumped! Could really do with putting up a thread on here see if anyone has any idea what the problem is!
All I know is that Im running 102bhp () on GSR induction & Supersprint manifold () on the limp home mode map!
And that its running rich!



im thinking towards possible airflow sensor faults.

anybody wanna lend a hand firguring it out.
 
Why can't the fault code be read?
