Is it possible for the cap on an opti to be loose? ive never installed one but my LT1 has been randomly dieing, although a big bump makes it stutter and sometimes it dies from the jolt, could that be a loose distributor cap? i know this is getting off topic but could that be fuel system related if sudden jolts cause my engine to cut out and sometimes die? just wonderin, and if this has happened to anyone else please let me know what the problem was
