Breaking up in upper RPMS - 6G Celicas Forums

Topic #46739 9 posts Started by JaxMadine
My buddys got a 94 with a 3rd gen. Just on saturday it started breaking up @ WOT in the upper rpm range. Any ideas of what could be wrong?
how much boost?

15PSI - 30MPG - Megasquirt Tuned
plug gap maybe
i love being able to blame the plugs or torque conv. on auto cars.

if its the same RPM every time its probably the coil
Did he change out his fuel pump when he did the swap? I've seen this happen on a 2nd gen CS motor.
ignition or fuel delivery ...

pump, filter, regulator
or coil , plugs , wires
