Thank you for your very helpful reply, that's what I did exactly right before this happened (Moved the car for few feets in the garage)

I starded the car today and engine was shaking for a 5-6 seconds and smoke was coming from the egzost after turned normal.What can cause this , seems like few spark plugs weren't working. I never had any problem when car was running or when I was driving. Is this related to fuel injections? Do I have to put something in to the fuel tank (If it is what should I use) Thanks guys Best forum ever

Thanks I did put it on 65 and still no cold air, I thought maybe freon is low and when tried that code test pushing recycle and outo buttons same time than start the car this gives you all the codes about the A/C and there when it was testing I heard A/C came on while it was testing.

I checked lexls.com tutorials and my A/C code shows "" Code 21=Open or short in solar sensor circuit."" anyone knows what is this code means and how to fix it.

It was aftermarket from ebay

While changing the compressor we changed the new R134. I checked Lexusguy tutorial and my code shows 21 according to book (21* Open or short in solar sensor circuit.) What is this means? Fuse or something? I like to find out this before going to the mechanic.

I put last year new A/C compressor and everything was good. Two days ago was fine too but Yesterday I put the A/C on and nothing I mean blows hot air hot hot air. Any idea, I can't tell compressor coming on or not but feels like does not come on but again I know that if freon is low it won't come on anyway. I still want a see maybe fuse (If anybody can tell me where the A/C fuse located) but inside the buttons A/C button lights up when I put it on. Thank you guys

Can you explain little more, thank you for your reply

I hear some noise from the back, not all the time sometimes. Sometimes 10-15 seconds. I have to say fuel pump but it is not like a buzzing noise. Other day I turned of the engine and after that I heard like water running noise (Exactly like water running throught the pipes kind of noise) and it took 4-5 seconds and it was gone. What is this? Fuel pump or something else? If this is a fuel pump how much labor we are talking about, I checked on ebay and people selling around $60-90 for fuel pump replacements is it easy to replace? If this is not a fuel pump what else can be.

Mine is the same, I hate it but I guess nothing we can do.

How do you clean MAF

Thanks for the reply and good information, I believe motor vehicles equipment was correct because when guys told me to push on the gas pedal until 2500 RPM I did it and my RPM was showing 1200 when his was 2500 and I believe his was right (Testing 100+ cars a day). Some how my RPM show low numbers because when I'm doing 50 mph still stays around 1000 RPM proves that I think. But still I don't know where to start and what to look for.

I don't have proper equipment but what should I look for or how to fix it if something I can do? I don't want a end up dealers hands, I rather stay and drive the way it is but if anything simple or I can handle why not I'll give it a try.

Thank you for reply, no check engine light or any other code comes on. I feel like you saying some sensor but no codes or check engine light comes on. I also start reading stuff and saw throutle clean up might help idle and power issues with the car but I don't know I can do it or not (I looked at tutorials from lxus guy) but again I'm not sure what the think of. Tell me this when you are doing 40-50 mph on a straight road what is your idle shows? mine is around 1000 even less. If you think this is a sensor issue (but like you said light should come on) how to fix or change the thing do you know? Thanks again

Anyone can help on this
