You ever pop a code 26 and 29 on your bonneville?

[@koolkatkustomdiecast801]

Love my 91 bonneville super clean car just had a bunch of stuff done to it.

@koolkatkustomdiecast801 I've had code 26. That popped up after unplugging my TCC to diagnose a shake at highway speeds. Ended up being the ICM failing causing it to misfire at high speeds. A failure in the ECM itself is not uncommon either.
