Best Spark Plugs?

Hmm I also have an 07 with 181k miles, I'm debating about getting new ones for mine.

How does your 07 run?

Car runs strong with 245k miles on it. Was a fleet car. Mostly freeway miles. Retired it a few months ago and driving it randomly CEL came on with the cylinder 1 misfire. First time ever. Also at idle it'll cut a little every few seconds but nothing like a surge. I did the sea foam, cleaned the MAF, the intake, and the TB. Nada. I also put in a new OE fuel pump about 30k miles ago. No major problems. It's been a hassle free cat except the regular maintenance. And I need to add a a qt of oil every 3k miles. But that's expected. It's build like a tank I tell you. Lol. I'm just trying to sell it and want everything taken care of for the next owner I guess.

NGK Iridiums. Strong!

At 245k I would say yes - but to test it

Run it and open the hood at night. Look for the spark jumping to the block that would indicate a bad wire

Switch the wire to another cylinder and reset the codes. See if the code jumps to the different cylinder

That's a great tip. I'll do that. Thanks
I did change the wires and the plugs together last time at 200k miles.

Just curious. So it does not matter which wire goes into which plug? I guess it's not like the old wires with the distributor.

oh I meant the whole wire, from the coil pack to the plug. Completely off and switch to another coil and plug. Just take the wire from 1 off and 2 off, and switch them. You should get a code, if it's still cyl 1 it's probably the coil pack itself. I seriously doubt it's the wires at 45K

Update: I changed the spark plugs with oem iridium and no more rough idle. Runs very smooth. Thanks for the help.

I still have my rough idle

I think my local Valero has water in its gas tanks. A neighbor says they definitely do in their deiesel - to the tune of $12k in damage to his truck. He has never filled. Anywhere else...

I'm with you Erik
I changed my plugs a while back and it cleaned up my idle a little but not much.
I'll be doing it again soon along with new wires and I may even get all new coil packs to.
