tech question: im having trouble at idle, sometimes it idles, sometimes it wont, and sometimes it pulses at idles (idles, the drops to try to die, then back up to idle untill i give it gas). ive messed with the timing at the distributor, and air screw at the intake, cleaned up the MAF, and shot some cleaner through the thropttle body, and ive tried the carb cleaner trick on the vacuum hoses to see if i have a leak, but cant seem to detect one. any ideas? when you hit the throtle, the response is good, but when it comes back down it dips below idle, and tries to die, then half the time it comes back to idle and is fin, sometimes it does the pulse thing and sometimes it dies. its a pregnant dog trying to crawl and feather the throttle, especially on hills going down
