Locetti problem
Hi all was looking for some advice please,,,, 2006 chervolet loccetti 1.4 petrol,,,,, well looked after car serviced etc,,,,, last week had a engine light pop up,,,, camshaft position sensor faulty,,,,, so I replaced it and job done great job,,,,
2 weeks later another engine light o2 oxygen sensor Bank 1 sensor 1,,,,so before I went and wasted money on a new sensor I swapped the bottom sensor with top,, same wires same plug etc,,,, so I was hoping if light came back it would now say o2 sensor Bank 1 sensor 2 but it didn't it still said bank 1 sensor 1,,,,so makes me think dirty fuel or cat blocked or part blocked,,,,,
I've done all the usual checks,,, unplugged each sensor and got new code o2 heater not working,,, and other sensor the same o2 heater not working,, so reconnected and erased,,, and then checked supply,, all supply's are there,, 12v heater to o2 sensors and signals are also there,,,,,
But here's the thing I shook the exhaust pipe really hard to listen for broken bits inside and nothing,,, but after the shaking I drove it again and no light,,,,
Please advise cheers John
Just to mention,,,, when I was driving down the road at 80km a nice speed for no reason the car pulled back to 60 for 3 seconds I got a fright it was like something grabbed the back of my car then let it go,,, strange,,,, no lights at that time only next day,,,, so it looks like that was the start of it and prepare myself so to speak,, hope that helps....

Cheers,,,,,, update,,, I removed air filter hose and cleaned out breeder pipe with some brake cleaner then reassembled,,,, then I ran a bottle of redex through the fuel tank took it for a hard spin and no more lights,,,,, fingers crossed,,,,, I suspect after I gave the exhaust a massive shake I disturbed some dirt and gave the redex a chance to clean it out,,,
Well here's hoping,,,,, 👍
