How to remove / replace your spark plugs
I have done everything that was told... My engine is running very rough now, i'm on the NGK 8s and I've gone back to the originals but it's still the same way. Something I may have done incorrectly is connect the ground cable before the positive cable to the battery when I was done.
What may this have caused, it my computer stuffed?

Splendid write-up on changing the plugs. I would add: Whenever you remove or replace the sparkplugs, coat the threads with anti-seize compound...on the threads only. Be clean and precise about it, don't goop it on.
The reason is that the compound will make removal of the plug easier in the future, and keep the corrosion at bay if water somehow gets into the area.
A good preventative measure that will save you big $ if you strip or crack a plug down there.

OK so I changed my plugs today with the BPR7ES gapped at 0.026". Took it for a ride just now and when I put it in neutral, say when coming up to a stop light, the idle drops to around 600 RPM for a few seconds then comes back up to 1100 where it should be and always stayed before today. Also, I had the BR7ES prior to running these BPR7ES but I dont see how that would effect idle. I of course see how plugs themselves can since they make the pistons fire but not sure what to look for here. Any thoughts on this guys???

Nice write up, did mine earlier this week in less than 30 minutes. Next time it'll only take me 15 minutes.
results aren't very noticable. Car does idle better and the throttle response is somewhat improved.
Thanks

good point

Service manual says stock plugs are good to 60,000 miles thats why they are Iridium..I took mine out at around 45,000 they looked fine, no gunk , but still got the BRP7ES which will be changed out every 10,000 Im thinking.
And torque them at 19 +-3 ft lbs
