Hard to start when hot

I have a `92 Swift 1.3 SOHC with 160K that has a hard time starting when up to operating temp. Cold start is perfect and if you only run it a few minutes and shut it down it will start perfect. It runs fine out on the road, but with a slight hesitation pulling away from a stop light when warmed up. There is a clicking sound coming from around the throttle body if you breath the gas lightly when idling. It don't overheat even in traffic. The cooling fan works fine. It has all new gas lines and filter. When it's up to operating temp it cranks fast and if you give it a couple light flushes of gas it almost starts, but not quite. If you hold the pedal to the floor it almost starts. If you give it a couple full pumps of the gas pedal it will crank fast and then barely grunt over a couple times and then return to cranking fast ... almost as if it retards the timing too much. I am going to throw a set of plugs, wires cap and rotor button on it, but it just don't seem to me like that's the problem. Any ideas would be appreciated. It's not a daily driver, but we use it a couple times a week and I may sell it. I'd like it to be running properly. Would the throttle position sensor cause that? Is there a way to pull codes off this thing w/o a code reader? Thanks in advance for any suggestions.

Repaired. I cleaned some grounds on the engine and firewall, dried out the distributor cap, cleaned corrosion off distributor cap inner terminals and it worked fine. Starts great hot, cold warm and no hesitation at all. New tune-up parts are going on it soon. It also needs the distributor cap base gasket.
I do have a question though ... there is a line running off the lower side of the charcoal cannister that isn't attached to anything ... I thought it should be attached, but can't find anyplace for it to go. I thought it may have been "my vacuum leak". Anyway it's working fine and it isn't attached. I moved the box when I put all the gas and brake lines on new early in the spring, but I can't recall taking that line off. Does it just hang like a drain? If someone could check yours and let me know. There is no VECI label under the hood of this car.
