Runs bad in the rain

I hope I am posting this in the right area,if not I apologize I am new to the computer. I am having problems with my 1997 camaro it is a V6. The car is running rough in the rain. I had a coilpack replaced last time this happened. I see water dripping onto the coilpack from the hood. I don't know what to do or if it it the coilpack again,the check engine light is also on. I put a blanket over the hood and let it dry out for awhile then went to start the car and it sounded alot better. Any advice about this or what it could be? Thanks

Fix the water leak into the engine compartment.

Re: Runs bad in the rain

Thanks. Seems it only does this in the rain. Any advice on what to use to seal it up?

Re: Runs bad in the rain

It depends on where it is leaking. Can you take a picture of where it's leaking and post it on the site? See my signature on how to post pics.

Re: Runs bad in the rain

Is the bolt missing or is the water dripping from the bolt? Can you use some Silicone sealer to seal the leak around the bolt? Sorry, it's hard to make a recommendation without more info.

Re: Runs bad in the rain

The bolt is there but its letting the water leak down on the coil pack. Once I get it all dried out the car runs fine. I will check into the silicone sealer. Thanx

Re: Runs bad in the rain

I suspect poor sealing of electics, HT leads or faulty leads.
A engine should be able to be heavly hosed down, and started /run without any problems. If the is it means 1 of 2 things
1/poor electrics (above)
2/Sprayed the dizzy to hard and got water inside (normal) blow off the inside with an air gun.

Lets say u have a faulty/abused HT lead with a higher resistance than normal.
Even a good boot will 'leak' as the current will then flow the easest path. Or u may get cross fire between leads.

At night time when the car is playing up, open the hood, u will see where the arcing is....do not confuse the slight glow with arcing.

The wrong size HT leads installed could be a problem also...a std HEI will blow visible holes in std points leads under normal conditions.

Re: Runs bad in the rain

Spray it down with WD40 when you expect rain, not a fix but may help ?

Re: Runs bad in the rain

OI have bever been a fan of D40 type ptoducts unless in a emergency.
The reason is that it colects dust and other stuff, which then cause a further problem down the line.
As System in good condition doesnt need these products

Re: Runs bad in the rain

As suggested by Steptoe, plug wires do age and become leaky conductors and arc to the outside. Especially if the spark plugs are worn or the wrong type of plug for the engine, ie, straight conductor vs. resistive type.

You might observe the engine running at night to look for arcs and the source of the problem will be found.

The fix for the leak, without pics its hard to tell as said by Camaro Dave, is to stop the leak. The vent, is it for the heater-A/C? Is it the vent in the hood?
One easy temporary fix is to run strips of duct tape over the affected coil pak to guide water away from the coilpak.

Or, strap an umbrella to the hood, or as you did, give the car a cape with a big yellow "S"..........Supercar! Able to accelerate faster than a speeding bullet, more power than a Hemi, and so mild mannered, gets 25 mpg.

Re: Runs bad in the rain

Its the vent on the hood. Someone advised me to replace the weather stripping. Hmm duct tape,didn't think about that.

No...a good set of HT leads and boots will last 15 to 20 yrs...."abuse" by pulling off by the wire is what kills them.
Soln is not to redirect water but to have good electrics...
Consider this
Rods with open engines on runs in bad weather dont have problems
Off roaders that go thru deep steams, dont have problems.
Engines that are hosed down dont have problems.
If your seals are not good also replace them, but it doesnt fix the source of the problem if electics are in not top condition.
