I'm hoping someone has had similar and maybe able to offer some advice.
Bit of history first. I bought the car back in September and on the way home the EML came on. I read the code and it showed the O2 sensor to be the issue. Fair enough, I know they are common so to be expected. The light wouldn't always come on, but every second trip or so it would come on. I had Performance Autoworks fit a new one which cured it. It had not been back on since.
Fast forward to last weekend when I picked the car up from TGM after having the gearbox out for the diff etc. It had been road tested and was fine but as soon as I jumped in, EML on! Code read and it was showing O2 sensor again. So I ordered another one from Hendy which TGM fitted today. However the light was straight back on!
There's a bit of loom extension for the circuit about 3 inches long to move the wire away form the manifold, it comes with after market manifolds. Tom removed this and cabled it straight up. Again, light on every time without fail. Tom plugged his diagnostics computer in and it's showing correct voltages. So we put the original one back on without the loom extender and no light. I took the car for a drive and it didn't come back on. Odd. The extender has continuity on all pins.
So the new sensor went back in with the extender and the light behaviour is back to what it was a few months ago.
Tom is a bit stumped! I suspect the new sensor to be faulty and perhaps an intermittent issue with the extension kit. But I'm not sure. Ran out of time in the end so had to leave.
Anyone had similar?
