QX runs beautifully, like never before, cleaning sensors took me 10 minutes. I wish I could do solenoids too. Cost nothing, I didnt even use any cleaners, just cleaned with microbiber cloth. Its just 2nd day of driving 50/50 highway/city. Will give update in few weeks.
It runs good, recently used fuel system cleaning "techron" and injectors cleaning liqui molly... runs better...I still have problem with CATS, I have feeling that on this car engine oil should be changed every 3k miles. It has 181k miles, so pobably need new cats, new injectors...Im not sure if ever going to spend that much...but it runs well
