1998 Safari Convertion Van with 4.3 engine

I been reading on the net and found a few data saying something about an intake leaking problem. That worried me but anyway, I have a smooth engine when its cold with it in drive sitting still and when it gets warmer it goes to missing, Its not a bad miss , it never stalls or anything, I have water and oil and it dont over heat and starts to a quick touch of the key , but it does miss , a scan says I have a misfire on the number one cylinder.
I have to ad that its very smooth when you get on the gas in drive, its always smooth when the throttle is open,
I wonder if it could be as simple as a plug or wire on the number one cylinder?
I had a few people say that would fix it . I have a smell of radiator water when the passenger window is up , no wet floor inside and no sign of the heater core leaking but that smell makes me wonder if it could be a intake leaking, then the last things the van dont hit a single time when I try to start it on a rainy day.
The miles by the way are 135k,
another tip i get the feel from ohio I could get in this van and drive to florida without any problem.
Oh yea one last thing , can an intake leak only effect that one cylinder and be a small miss and no miss at all when you pull off?
Thanks in advance Terry H

    i pulled that plug it looked fine , i have since changed the rotor button and distributor cap it still shivers like it use to .i have a feeling when i change the plugs and wires its going to do the same thing. I put a new plug in the number one anyway but no change.

    but anyway thanks for your input , oh yea the cap and rotor button fixed the rainy none start problem i had.

My 1997 safari was doing the same. After being shut off for a short period of time it started as if it was flooded. If I put the accelerator to the floor it would fire up. As well, I had no engine codes to report. I replaced the fuel pressure regulator and everything is great. It was leaking fuel into the engine causing it to act flooded when starting. Once started, the computer system made adjustments for the leaking fuel so the engine ran fine. If you turn the van off and immediately try to start it, it should fire up. (don't give it time to leak extra fuel into the engine)
