Last week i bought an 84 tbird turbo off a friend of mine. Back in sept he was driving it and it jumped time on him pulling into his neighborhood. He didnt drive it maybe 200 yards after it jumped time but he changed the timing belt and reset the timing and it was popping them too, after 3 tries at resetting the timing he gave up. I think the timing is still off. Above 45-50mph the car runs smooth and doesnt miss or hesitate but at lower gears it does miss and hesitate some. The popping sound only occurs around idle. He told me he changed the plugs and wires too. Any ideas what it could be??
here is a couple videos....the audio quality isint that great but you should be able to hear the popping sound
just idling

Have you verified that cam timing is correct or not? I'd start with that. What plug wires are those? The best thing I did for my 2.3T was pick up a set of genuine Motorcraft wires.
Don't neglect the basics. Check fuel pressure, ignition timing, compression, and I would also thinking about a leakdown test to pinpoint any problems in a particular cylinder.
Make sure you dist is pointed the right way and going to the correct cylinders as. Well.
never had this problem, but what about a tipped rocker?
