So I changed my plugs (all by myself without any help, it was awesome) and the car drives much better but I'm still convinced that I didn't plug them In right or something. If one of them wasn't plugged in and working I'd notice a huge power loss or other adverse symptoms right?

When I first started up the car it drove fine but at idle the RPM's kinda went up and down ~200 rpms. Could this just be a break in thing because it doesn't seem to be doing it anymore.


Also, I was do excited to drive my car after I installed the new plugs that I took it around the block with out the air filter on (I was "recharging" the K&N filter when I was doing the plugs and It was still drying). Surly a short drive in the town wouldn't of hurt it right?

Thanks a lot guys.

Highly unlikely you did any damage without the air filter on a round the block trip, unless you drove through a massive volcanic dust cloud, but the electronic engine control expects it to be there to properly set mixture and timing, so is definitely a bad idea longterm :yup:

A spark plug/wire problem (bad plug, bad wire) will show up as a rough running engine, not a varying idle... If you cross wired the plugs, you will likely get very rough running and backfire.

A varying idle is more likely a vacuum hose not properly sealed or a disturbed electrical connection... take a look around where you were working and see if there is any vacuum tubing or wiring that was loosened and slide it back onto the connector...

Another trick to isolate a leaking vacuum connection is to run the engine and spray WD40 on the vacuum connections. When the culprit connection is sprayed, the engine will smooth out.

You would know if one wasn't installed right or if the wires were crossed, it would run really rough and you would hear it misfire. A short drive around town should't hurt anything, but as jimbo said running without the filter will change the way it drives due to PCM expecting it to be there

I had a similiar problem when i put in new plugs a couple weeks ago, i believe it was some type of grease or cleaner transfered from my hands to the plug which afected the timing of the plugs slightly.. i Just let her run easy to burn off the grease and it runs crisp now...
