Im fairly new to lambda sensors, just replaced the cat with a low mileage 2nd hand cat, had to use a fair bit of brute force to get the sensors out the engine is a z22se vauxhall 2.2 (fitted to my vx220) after replacing the cat (still using the old sensors) the MIL light comes on after about 10 miles of driving after a ecu reset. I reckon the brute force and a combination of 90k+ miles has put the sensors past their best, question is....
dealer is too expensive theres a site online that does the sensors with proper cables for 60 quid each. or i can get universal ones which require soldering which are 20 quid each. (i dont mind soldering at all)
which is the better option (i would say the cheapest one - seems to me im paying 40 quid for connectors - are these sensors basically all the same thing ?)
anyone had experience of using the universal ones ?
thanks
