Dropped the car off last night at the dealership's service dept., they called today saying that both front seat belt buckles need replacing, I asked how much, dude said $0!

That's awesome! so that just leaves the misfire mystery

I actually had resolved that issue by replacing the spark plug although it probably needs a good tune up all the way around. The noise inside the cab is still very loud. It's either b/c I don't have a resonator or one of the engine mount bushings is worn or something else.

Good deal. Did it get rid of your codes?

Apparently so. I replaced cylinder #2's spark plug before I took it to Honda...he didn't mention any other codes.

No more SRS light! Now, I'll be taking it to our HondaPro shop to have them do a general checkover to see what recommendations they want to give me. There will be many I'm sure since it'll be the first time the shop has seen this car since I bought it. It does seem to run a little rough still, sort of a puddering sound, and the RPMs seem to be higher in each gear than our 3 Accords. Hopefully, they can figure out why it's still so loud inside.

Ignore this, Civic cannot be compared to an Accord.


Replace the other 3 spark plugs to make a matched set?

I wanted to see if changing that particular spark plug would make a difference with the misfire code, which it did, but yes, I will need to change the others, I'm sure that'll help.

Thanks!

Well, after taking it to our honda shop, it was discovered that the loud noise in the cab is a result of the rear engine mount bracket needing replaced. Also, the high RPM's is due to the tires being taller, which makes total sense now. So, now I have to remember to shift sooner and know that the speedometer will be off a bit, meaning that I'll be going faster than what it's reading.

That makes no sense, mechanically.

Engine RPM at any given speedometer number is strictly a mechanical function of the transmission gear ratios. The speedometer itself is just a glorified RPM display for the differential, only it's marked to show you a calculated and more or less sorta accurate road speed instead of the RPM of the differential.

The Civic has a small lower power engine with less torque than the Accords..... engineers makes up for that by gearing it to keep the RPM a little higher. An EX/VTEC trans will produce even higher RPM than the trans in a non-VTEC Civic (at identical road speeds), to give it a more "peppy" feel while driving.


If you stick taller tires on it, road speed will increase more than the speedometer says, but the trans gear ratios can't change.

I stand corrected, thanks for the explanation!

I guess I should have said something like

The RPM will always be (wildass guess, random numbers) 3200 at 70 MPH in top gear-lockup no matter what size tires are on it.
Or whatever RPM/MPH numbers you always get on your car..

Glad to hear! Figured it work out for ya

After having our friendly honda shop replace the rear motor mount, I can actually hear the radio; it's much more bearable to drive now.

I noticed that when I drive my son's 2001 Civic at 70 mph with 205/55R16 tires, the rpm is 3400, but when I'm driving my 1999 Accord at 80 mph, the rpm is 2900...any thoughts?

Yeah. I told you this a month ago:
