I had my mechanic (Monaco Motors in Canoga Park) look at the car and check the fault codes, etc.

Suggestion
Unless he remove and inspect each coil, he won't be able to tell if they are bad or not.
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

So my 996 C2 has decided to freak out in the rain storm we're having here in L.A.:
CHECK ENGINE light comes on.
ABS light comes on.
PSM light comes on.
Engine sputters and dies on acceleration.
Engine surges wildly on idle.
I can't believe this isn't somehow related to the rain (it happened twice during heavy downpour on Monday and Wednesday, but was fine on drier Tuesday).
Anybody ever had a similar issue? Should I just wait for the car to dry out and try again? Or just bite the bullet and have it towed in for repair? Any advice appreciated. Thanks.
All I can think of is check and see if you have water getting past the seals under the hood in front and in the engine compartment. With that amont of errors I'd think it's a connector. Have you added anything electrical lately? Verify connections on sockets and look for water near the fuse box. Do not clean any white stuff off of plugs and sockets, its to keep water out and preserves metal contacts. Actually not sure where the ECU is but I think its in front so make sure it isn't getting flooded.
Yeah this rain has been crazy all week, mine is tucked away in the garage.
Coil packs are often slightly cracked, which is not a problem until water gets up in there.
Do you have it parked somewhere?
It's supposed to dry out tomorrow (Sat), maybe the problem will solve itself, wouldn't that be nice.
Good luck.
Thanks for the advice.
I left it parked (at my office) all day today. Will try it again tomorrow, which is supposed to be relatively dry also.
I'll have the coil packs looked at. Just hope I can drive to the shop and not have to have it towed.
I had my mechanic (Monaco Motors in Canoga Park) look at the car and check the fault codes, etc. They said there was no problem with the coil packs. Their diagnosis was that the clamps were loose on the K&N air intake and that was causing a compression loss ....
HOWEVER, it rained a couple of days ago and the car did the same damn thing again ....
So I'm going to take it back in. Stay tuned. Maybe I should just replace the coil packs whether they look faulty or not?
Uuum, what? Compression loss? Because of a loose connection from the K&N to the throttle body?? Hmmm. Do they sell snake oil out of a covered wagon too?
I mean maybe if there is a BIG "leak" at the throttle body upstream of the MAF, that could make the MAF signal not jive with the amount of air that's actually getting into the engine. But still, I that would have to be a pretty big leak.
I say go back to the coil packs; lots of wet-weather problems can be attributed to them.
if it rains and the car misfire, sputters; the coils are bad. Unless he remove and inspect each coil, he won't be able to tell if they are bad or not. We are talking about hairline cracks.
Hapefully if he is a ghost writer and inherently good at reading persons he didn't evaluate the shops mechanic talking to him about whats wrong with his car and procede to write him out of the script. Wouldn't blame him though
You guys are getting so predictable. How come nobody went for sunroof seals?? Mechanic told him sunroof seals were worn causing vacuum loss and it only happens when it rains because well... nevermind
Who was it that blew the engine because of water getting into the intake through the brake booster due to clogged drains. I think that was a MKI. Is that more of a MKI problem or equal with MKII? What year is the OPs car?
#10 for cracked coil packs
