AndyR Posted February 24, 2021 Share Posted February 24, 2021 Well it has been blowing from the flexi for quite a while. Bought new part, and after it turned up, we got a deluge of snow. Now the sun was out today, so up on ramps and swapped out old for new. Sounds a lot quieter now. Quote Link to comment Share on other sites More sharing options...
Vauxhall Owners Club Posted February 25, 2021 Share Posted February 25, 2021 Great news Andy, probably get more performance and better economy as this would have affected the Lambda sensor to result in overfuelling the engine Quote Link to comment Share on other sites More sharing options...
AndyR Posted February 25, 2021 Author Share Posted February 25, 2021 I am hoping that it will be what the cause of the engine light staying on. Just need to talk to the brother in law to get his obd and clear out the fault codes. Quote Link to comment Share on other sites More sharing options...
AndyR Posted February 25, 2021 Author Share Posted February 25, 2021 Also there are 2 lambda sensors on the astra. One is inthe top of the catalytic converter, and the other is just after the flexi bit. So hoping they'll talk to each other and the ECU, and start playing nicely for me.

Vauxhall Owners Club Posted February 26, 2021 Share Posted February 26, 2021 That should definitely improve things all round now. Be nice to know if you see an increase in the mpg Andy Quote Link to comment Share on other sites More sharing options...
AndyR Posted March 21, 2021 Author Share Posted March 21, 2021 Well I finally get to give the car a good run tomorrow, as daughter is back at college. I did get the engine light turned off, but it came back again after a short trip. Turns out that I need to have a chat with the EGR valve. This is going to get a clean out tomorrow after the college trip, and then I can see how it goes on the afternoon pick up. A good 50 mile round trip should hopefully sort it. I can also check if the mpg has improved. Quote Link to comment Share on other sites More sharing options...
AndyR Posted March 28, 2021 Author Share Posted March 28, 2021 Well after travelling some 192 miles, and using about £20 worth of petrol. Checked the fuel economy with the online calculator. It has worked it out that I got 54.5mpg, and used 16 litres of fuel at a cost of £5.68 a gallon. It also worked out that it was costing me about 10.4p per mile. Now I can live with that sort of economy. I was so impressed, that the car got a birthday, cleaned and polished inside and out. Quote Link to comment Share on other sites More sharing options...
