Maybe reduce the speed sensor distance, making it closer and see if it stops. Easy, no cost , troubleshooting step.

This is common when the speed sensor isn¡¯t working.
If you buy obd 2 scanner like an Ultragauge you can monitor vehicle speed. It won¡¯t be accurate but it is important.
If the sensor isn¡¯t working it will read 0mph.

Subject says it all. Have 2.5 installed with Precis ECU the harness conversion done by Busaru. Stock '91 auto tranny and stock 14 inch wheels. At 65 mph and above the engine starts bucking. The only way to stop it is to reduce speed below 65 mph. On a few occasions I have managed?to hit 70 before bucking sets in. At 70 mph the tach reads 4000 rpm. Has anyone got any ideas about the problem and how to fix it? I should be able to turn 6500 rpm easily with this engine but I have no particular need to do faster than 70 in most cases. The VSS is Busaru and is set 4 mm clearance from stub axle flange?bolts.?
All comments and and suggestions would be appreciated,
