Hi, sorry if this is long winded but here we go. 2002 Honda Jazz SE Sport. My Catalytic converter was stolen a little over 12 months ago, Had a new one fitted at significant expense, but soon after, the engine light came on. The diagnostic code showed a problem with Bank 1 Lambna sensor (the one after the cat). The dealer cleaned it to see what happened. After a short while, the engine light came on again with same error code. A replacement sensor was ordered under warranty but supply problems took many months before replacement arrived. Less than 20 miles, the engine light was on again, same code. Now past 12 months warranty, I did some googling and a faulty EGR valve was suggested. I replaced this but the engine light remains. Also, I get some hesitation and loss of power soon after setting off (warm or cold). Dipping the clutch and a quick rev clears it. The MOT is due soon so I'd like to sort this reasonably soon. Any ideas or suggestions....Thanks in advance.
