Just got an 89 supra and it runs pretty good. It has an oil leak and a bhg, the owner said it had a rod knock but it deffinately doesn't, it is a slight tick noise, I'm thinking lifter tick or valves. That is not the problem I'm worried about. It runs good and idles good, but when driving, and you give it gas (around 3 or 4000rpms) and then let off gass it dies. I have a few ideas that it could be like the injectors shooting in too much gas or a bad o2 sensor. I'm not a mechanic so I don't know for sure so let me know what you guys think. Maybe its happened to some of you?
