Question about 2004 Toyota RAV4
I tried putting methyl hydrate in the fuel tank as thought it might be water in the gas, didn't help it a bit. Took it to my local dealer and they haven't figured it out as yet. They thought it might be the ECM and sent for another one, put it in Friday , nothing changed, and its costing a lot to try this and that ?
The ECM is usually the last thing in the book to try after everything else. It's also pretty much the most reliable electrical component on that car.
Check spark plugs and high tension wires (spark plug leads).
Check condition of air filter.
Check and replace fuel filter.
Check manifold air pressure sensor.
Check MAF sensor.
Check O2 sensor
And then report if none of those turned out to show any faults.
By the way, the MAF and MAP sensors may require an OBD 2 diagnostic computer to read properly.

turn it to the right and it just clicks? Turn it to the left and it won't turn, right? Well put some muscle into it and make it turn too the left, your dad undoubtedly turned it abot 5 clicks past stop and it's just tight. It will turn, Good luck.

My mom just had her 03 Rav4 begin the same problems. We took it to one of the best mechanics that we know. He told us for a brand new ECM would cost $1200. Now if the car is still under warrenty...which I don't think yours is anymore, it could cost only about $550. It also maybe a good idea to look at Rav4's of the same year that may have been in an accident or something, and see if you can have that ECM salvaged. I would also like to mention that the guy above says that they can't be reprogramed...they can be, its just recommended that you don't because then basically it would breach the conditions of the warrrenty. Also, there was a warning sent to Toyota when this problem arose, but it was never put out as a recall therefore no one knew about it until it began to happen...I hope this helps you. It helped my mom out, I wish you the best of luck.
