thanks for the offer though!

 

Did you not read my post?

Get the code.

The lambda can do that to the throttle response. It governs the cars fuelling, and when they fail they screw up both the idle control and the closed loop fuelling.

I changed the MAP again but it didn't work and in doing so I reset the ECU and as soon as I started her back up she chucked a CEL. Took it to a dealer and the TPS sensor was to blame. The car still driveable - but erratic - so I declined the

 

True...
