sorry, this is a bit long but please bear with me cause i need to take care of this and i could really use you guys' expert advice. so i get a letter in the mail notifying me
that someone reported my car as having excessive smoke coming out my exhaust on I-80 in emeryville CA. aside from having no idea that there was even a problem, i found this news kinda disheartening. besides not wanting to be one of those guys with a smoking car, i know its an indication of some sort of problem.
at idle there is no smoke, but, in park, when i rev the engine high, i do get a bit of smoke. so i'm thinking i have a rich fuel condition... but i don't really have enough to go on at this point.
now, here's something that i feel may be somewhat related. soon after i bought the car a couple of months ago (71 SS 350, holley intake, edelbrock performer 600cfm) i began noticing a little misfiring, or stumble or an off rythm lope. plugs are good, wires are good, timing is good, air cleaner is clean. i'm worried that they may be something wrong internally.
more recently, i started noticing that when i'm driving on the freeway, once in a while, i'll hear a little bursting sound coming from the engine compartment, like as if its backfiring through the carb.
i haven't checked the vacuum yet - what kind of psi should i be looking for?
can anyone give me any leads as to what this problem could be?
again, sorry for the length of this post, and i appreciate anything you guys can suggest.
