    Rotten egg smell

    That or the fuel itself. The smell is the sulfur oxidizing in the cat. Changing the cat temporarily alleviates the symptom, but is not the cause.

    Engine overheats on highway with AC on

    Actually, air is a pretty good insulator. And an air pocket on the ECT sensor might not show up on the temp gauge.

    Oil level?

    Well, I will be sure to get rid of it after 15 years.

    So drivelines that work?

    The MA70 wheel base is longer than the JZA80. I don't know the model on the Lex.

    Oil level?

    If you can't find the chain wrench at Harbor Freight, you will have to get it from the tool peddler in the Frito Lay truck like I did all those years ago. I haven't seen that big of a wrench at Sears or other places.

    7mget runs good til 5psi at wot then feels like itsvjust all motor im running 9 psi

    Rich doesn't usually bog unless it is retarded rich without a load. I wonder if we are not getting all the info, like a giant black cloud of smoke at the same time.

    7mget runs good til 5psi at wot then feels like itsvjust all motor im running 9 psi

    Just an FYI, that is called the short block. If you had a head on it, it would be a long block. I am not sure what you mean. The car's acceleration doesn't increase as the PSI goes up? Strange that it pulls harder at 3/4 throttle. That can happen with low airflow velocity. Fly by wire cars...

    Auto tranny limit?

    The clutch pack can get up to 650 degrees. The torque converter is no slouch either when it comes to BUT production. Get a cooler.

    How hot is considered overheating?

    This is why there are eletric fans that cycle by temperature and high side pressure. The temp switch closes at 220ish. To give you some idea when the coolant is getting warm and needs to drop.

    Bouncy Speedometer Needle?

    On some models (Cressidas and Supras rarely came in the shop) I would spray white silicon grease, and the cable would move smoother. If it bounces early and smoothes out, you don't need a whole cluster. A speedo shop (if you have one in your area) can rebuild it. You will have a sticker inside...

    Bouncy Speedometer Needle?

    Rule of thumb: Bounces to start and smoothes out is the speedo head. The wound up spring has lost some tension. As the drum spins faster the spring is wound tighter and it stops bouncing. If it bounces consistent all the time at all speeds, that is the cable.

    Upgrading Factory Alarm

    I wouldn't think it was either.

    How hot is considered overheating?

    And "alittle" isn't a word any more than "alot". Ok, enough of the grammar patrol.

    How hot is considered overheating?

    Standards are older than the MA70. They (standards) go through updates. He does. And the BTU content that the condensor pushes into the radiator is very high.

    Engine overheats on highway with AC on

    It has been around 100 in StL. A lack of adequate airflow over the radiator when the AC is on will cause your problem. Of course, you have to verify lack of airflow. When the AC is on, the condensor takes all the heat from the cabin absorbs it into the evaporator, then dumps it to atmosphere in...

    Engine overheats on highway with AC on

    No, the problem as already mentioned is that the coolant wouldn't absorb as much heat. To give a little more technical explanation, the lower cover creates low pressure behind the radiator, forcing the air through. Otherwise, it would spill over as IJ said. If I was home I would stop by and...
