i've got an automotive project based on a 16f877 that works fine in 99% of applications, but when i
get it in a car with a magneto ignition, my PIC is freaking out .. resets / locks / jumps to random
locations in code.

Anybody have tips on what I should be doing to 'harden' the PIC against this kind of noise ? the only
pins i haven't done anything with are RB6/RB7 which i need open for ICSP.  All other unused pins are
grounded via 4.7k resistor.

just general tips would  be great .. thanks !
