01 firebird v6 idle and hesitation discovery I noticed something new, which after hours of reading, did not see mentioned.
I did the normal wires, plugs, fuel filter, which didn't clear the problem. There was no SES or error codes and the coils ohmed out within tolerance. This morning it rained and I went out to look the situation over, and noticed water dripping down on top of the coil pack. There is a black plug holding down the drip tray, directly above the center coil. I repaired the leak, cleaned up the pack, applied new heat sink compound and replaced the coils, ending the battle. The idle returned to the normal 800 rpm from the 500 rpm experienced during the problem.
Was this coincidence or did dripping water cause the coils to fail?
I thought others with this body style might find this of use.

Warshrike, did you do that during your build while the motor was out or not? I'm thinking about doing it, but it looks like a PITA do do with the motor in, but then again, i could always move somethings around and attempt.

Beendue2, yes I'm in Lubbock.
Birdoprey, I did mine with the motor in. I used self tapping sheet metal screws and just a bit of luck. I had to make sure the coils would fit in a good spot without interference from the taller valve covers and the brake booster/vacuum hose.
I see a lot of cars now have splash guards over the coils straight from the factory. No water dripping down into the ICM anymore.

I'm having kid of a similar issue with my 02 V6 Bird. But m problem is that if I pus the gas pedal hard, it stutters and hesitates really bad. If I feather the gas it'll increase RPM ok but it limits my speed to about 50mph since if I gave more gas it would hesitate so bad I lose speed. Think a coil pack is the problem here too? I also just did a Plugs/Wires tune up.

^ There aren't many of those near by me. I'd probably spend more in gas trying to get TO a junkyard than the thing would cost! Haha I'm trying to work out a deal with a guy at TNFbody.com. Earlier today I pulled each plug. I'm running Bosch Platinum. All looked good but the #2 didn't have asmuch arc-burn on the ceramic piece in the middle as the others did. I put in one if the old Delco plugs to no change. I tried one if the old Delco wires to no change. And I left that plug unplugged to no change. Seems like it has to be the coil. Is it common for just half of one if those to fail, killing one cylinder but not the other?

If so, move the coil packs around. See if the misfire follows it. That'll narrow it down to one coil, meaning you'll only need to replace that one, instead of all three. At least until you can afford to swap out the other 2.

Saves me the trip, and gives me the convenience of reading/deleting any codes at any time, anywhere. Plus, it helps when working on your friend's cars too.
I know money is tight, but I think I spent maybe... $45 (with a discount) and free shipping.
