16V Engine sputtering after rain

I had that exact problem... Tried everything and looked for wet connectors
but no luck... On cold humid mornings it would run like crap sputtering and
spitting until it finally warmed up. I Finally gave up and took it in and
the recommendation was to replace the hall sensor. Problem solved! Even
after giving the motor a steam cleaning I have no problems no.
If your hall sensor is already broken (zip tied on like a lot of 16V's are)
then it's a good time to fix. it. I ended up replacing the distributor
complete but I think there are sources for the sensor in a rebuild kit.

<dd> <font size=2>my car sputters like that everytime I start it for
about 1 min, then the idle goes to about 2k, falls down to 4-5
hundred. It repeats that a few times then levels out at 950.
I haven't been able to figure out what the hell is causing it yet.
Sometimes if I manage to give it some gas and keep the r's up around 1500
for about 40 seconds she will level out just fine after that. When
I first got the car I had similar problems when it rained, I found that
the PO had put on the el-cheap-O autozone ditributor cap so I replaced it
with a Bosh and haven't had rain problems since. Let me know what
ya find out cause it's pretty embarrasing when the car sputters like that
when I fire it up while ppl are checking it out.</font>
