    Were the plugs done at same time as wires?

    Please confirm which engine. If it is one with plug wires & they haven't been changed in quite a while, that's a good place to start.

I'd clean out the mass air sensor , and I'd buy a tube of dielectric grease, and a can of electrical spray cleaner, or contact cleaner. Then I'd disconnect battery & remove as many sensor connections as I can find & spray them all & apply a little of that grease to all the connections. Go to autozone or Pep Boys & get them to run a free trouble code scan while your there, it may just point you in the right direction. Get back to us with codes, if any.

Did you put plug wire grease on the ends of the wires? especially at the distrib. end. If it has a distributor, check the cap for cracks. One good test is to use a spray bottle, and spray the plug wires, the distributor, and see if the rpm changes. It shouldn't. If it does, you should be able to see a spark jumping someplace, and probably hear it as well

The engine kills when it's wet outside (raining or just rained)


It is likely that your front oxygen sensor is getting wet.

Distributor cap is cracked or the gasket between distributor and cap is bad.

Wet weather


Clean the throttle body thoroughly with carb cleaner - and unbolt the air flow unit and do same to that (gauze gets clogged -unit is bolted to front of throttle body with two bolts & a couple of small water hoses to it as well as wires). Just possible that air flow sensor is getting damp & is the final push to it thinking that engine is still cold, which enriches the petrol mixture (chokes), hence stalling attitude. Lights could be the Oxygen sensor (or others) reading appalling exhaust mixtures, due to over-rich mixture.

Car stalls in wet weather


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.
