i think i may have narrowed down my problem but i want to know the symptoms first.
can u guys tell me the the list of symptoms of a bad pickup coil and also a going bad pickup

my problems havent changed yet. the takes a few seconds longer to crank before it starts, once it does it runs but the idle very choppy as if it has a miss, and then the main problem is when i cruise at any speed below 2k r.p.m. it bucks and surges.
iv replaced EVERY sensor except for the TFI but i had that checked about a month ago and it was good

also if this helps: whenever the car is turned off or dies i hear ONE SINGLE ping coming from the distributor
