After a failed attempt to get a Supra to run good,hold water and idle.I am going to cut my losses. But before I move on, I have a couple of burning questions.I have blow off valve that goes to atmosphere,My guess thats not good for A/F ratio .The EGR was removed. Not sure about the advantage of that.It's true that most problems are the owners not the supra. I did learn alot from this community. I just ran out of money and patience.
