98 Stratus trouble starting and stalling when damp wet weather
Has happened several times in past few years. Have replaced wires and plugs more than once and distributer cap that appeared burnt. Always seems to be in foggy or really wet weather. Recently started in fog but then died a minute later when entering on ramp to freeway. Avoided another tow when held pedal to the metal and cranked several times. Then slight press of pedal to give it some gas and it fired up. Rough and sluggish for a minute but then cleared up. Always in damp weather. Distributor cap again? Are fuel injectors effected by weather?

Re: 98 Stratus trouble starting and stalling when damp...
Cap is a possibility...try getting a regular spray bottle that you can fill with water....start vehicle up and lightly spray the wires and cap. as you spray watch and listen for an arcing sound. this may help you determine what and where the problem is

ignition wires and coils are very common replacement items on these vehicles, damp and wet weather are sure signs of misfires, stalls and no start conditions, have your local technician test for coil/wire arcing when wet.
if it only does this in damp weather, its more likely its in the ignition system. if it has a distributor check the cap for moisture and cracks. if it does have a cap. spray wd-40 inside cap to displace the moisture. WD stands for water displacement. when its dry outside and engine running. get a spray bottle and fill it with water, spray the dist. cap and wires. if there is a problem the car will chug and almost stall out. if this happens, thats the problem. have a good day !!
If this only happens when it's damp out, chances are your spark plug wires are arcing. When was the last time they were replaced? If they're factory wires, they'll be marked with the year they were made on the wires. Usually these won't last more than 10 years or 100,000 miles.
If they're in question, change the plug wires, spark plugs, distributor cap and rotor.
If it is happening more frequently in cold or damp weather it could be a spark issue. Wet or damp weather can effect spark plug wires if there is even minor damage to them (usually occurs durring rain). The other things that come to mind are the fuel pump and lastly the fuel line check ball that is in the fuel tank. If it is leaking then all the fuel in the line will drain back into the tank over night (pressure lost in the fuel line) and this will cause repeated, extended cranking when you first start the car in the morning or after the car has sat for several hours.
I'd have a free scan at parts store for any trouble codes first , just in case, if no codes come up then I'd consider a new cap & wire set. One of , or the most common problem with hard start in wet/damp weather is plug wires & cap, especially if they haven't been changed that you know of since new.
i think you have a cracked distributor cap that is alowing the moisture to get inside of it. i would replace the cap. you can test this but beware if it is the cap the car will not start until all the moisture is dryed out of it. start the vehicle and spray just a fine spray of water on the cap if the vehicle acts up it is your cap or possible a plug wire
Take a look at the ignition system, most likely there are coils and ignition wires on this car, but don't quote me on it. However, this is very likely on a seventeen year old car.
Anyway, if the wires are more than four or five years old, it might be a good idea to replace them as moisture tends to get into the insulation and cause a misfire or stall. (I had this problem with my '89 Tracer and it drove me nuts). Another issue is check the ignition coils and make sure there are no cracks as these will less moisture in and cause a misfire.
