Hi
This was PITA to resolve... but, I got it sorted in the end!
The car came in limp mode, not revving above 3k and very sluggish...
It ended up by being among other issues, a faulty IC in the actually ECU, engine control module, which luckily I kinda had the parts to get it repaired.
Follow me on this video to see how I got the the bottom of the problem, and how to resolve it.
The car came with other issues though, in case you want to those repairs the links are below...

Like always, thank you for watching!
I am a Toyota tech myself,but since I've started watching your videos I find ways to improve myself!keep the good stuff coming,thanks alot!!!
I have seen it all. It was a very good diagnosis and a superb repair, not just replacing ECUs but fixing them.
Watched the whole show. Great! One thing I really wanted to see though, was soldering the new/used chip back on. Thanks
Another great video for all auto technicians ... where electric meets with electronic ... don't you have any cases not with happy ending ... you should have some , but its natural that you release the ones that are succesfully repaired , thanks for sharing ,
My DIY skills are nowhere near this level. But I watched it to the end. I think I will never do anything similar when repairing cars :-)
Great work you've done there. I would recommend you were an antistatic wrist strap while working with sensitive electronics. Also please remove the plastic protective sheet from your beautiful UNI-T multimeter, so it will be easier to be read by the camera. Again, thanks and great work!
Awesome diagnose and excellent execution.
Enjoy the long vids, I will certainly use that fantastic tip about using the aluminum tape as a heat screen. Big Thumbs Up.
for chips like this you can use chip quick or higher leaded solder to dilute the solder,
Nice job Luis.. you are very patient.
OGM you are the best mate nothing can stop you .Congratulations 👍
i think this is one of your best video so far thanks for sharing
Good diagnosis and repair awesome sma rework pat your self on the back your one of the best in the industry Big thumbs up 👍
Another great video. I have in the past used part of a split pin to replace a broken pin in a plug as the correct item was not available to me at the time. Keep up the good work.
I watched all the video and loved every second. Wish I had half the skills you have lol. 👍
I watched all your video and i like what you did ... Thank for all the tips and your information. Keep up the good work. !
Great video, I actually picked up some tips watching you.
the best. I have enjoyed every second of this video so far.
Repairing a surface mount PCB by hand-amazing! As you say, replacing them is not cost effective.
Hard work I really enjoyed video I have similar problem for m. Benz Vito 646 p2526 which giving me headaches. Turbo is not kicking in. Its in limp mode
