Lexus Mechanic with Techstream Software in South FL
 

Hello, my 99 LS400 has been running horribly lately, misfiring on 3 cylinders and I haven't been able to hunt down the issue.

I've changed just about everything (ignition coils, spark plugs, injectors, o2 sensors, etc) besides my fuel pump and TPS, i even sent the ECU to be rebuilt just for peace of mind, but no luck.

There's no way in hell I have low compression on 3 cylinders all at once, I can't bring myself to believe that.

I'm at the point where I think Toyota Techstream will help me out by narrowing down the issue. My car runs like **** but doesn't blow smoke and seems like it is a lean misfire.

My car has misfire codes on cylinders 2, 5 & 7.

Anyone know a good shop in the Boca Raton area that has toyota techstream software?
