OP: If you search, you will find a lot more useful information than the replies that you will get to this thread. Your question has been well answered many times, and I think that there is a sticky thread here someplace. Try the Tech section.

RR - Get over it. It isn't that big of a deal.

So, let me be sure I have this straight. Apparently, it's not permissible to dispense free and accurate information along with a little humor and (deserved) sarcasm injected, without posts being deleted/edited or people calling for the thread to go back "on topic". Yet, concurrently it seems perfectly acceptable to discuss a member's profile pics in that same thread.

Gotcha. Gotta love a double standard!

Maniac - Thanks! I have not seen that one before.

RR - Normally, I wouldn't but this thread died an ugly death a while ago.

I also never objected to you making a little fun. I just don't want a big flame fest between you two because I am selfish and don't want to read it, and I generally like reading what both you and Maniac write. Have fun!

People be "e" thuggin LOL.

I understand sarcasm being used from time to time as long as it doesnt cross into the "rude" section. I have found a lot of good information on this site and the people for the most part seem really cool and helpful. I can also tell most people on here are pretty knowledgable and willing to help. I like that.

As far as your engine issues, my 8 has about 105K on it. It takes it about 2 seconds to start when cold but on a warm start it sometimes take about the same as well. I had a leak down and compression test done and all tested good...so dont be too worried or let compression be quick to come to mind because of that one issue, even though I agree with you keeping compression issues as a thought of why it could be doing this. The best way like they said is to have a compression test done. Also another thing to check would be when its cranking to start...does it sound like a strong crank or kinda like its struggling? The reason I ask is it could be your battery as well.

Guess some people are so sensitive they can't take a joke, or have never seen "ethug.txt" in their travels on the internet.

Yeah, my car was cranking slow so the dealer mechanic insisted on installing new battery, although I didn't think it was bad [had it in there for a compression test which it passed at 95K miles]. Anyway, I talked to the mechanic for a couple of minutes after he installed the new battery and insisted that it wasn't the motor either from the symptoms and must be in between. He checked it and found corrosion on the terminal post of the started motor. That WAS the problem, and I think that it is something everyone should check because of where the starter is and how much gunk gets on it.

All of that long winded stuff is just to agree that yes, there are other things that can cause a long start than a bad engine.

In drive you could be at 2k rpms doing fifty.....if you want more power drop it down one or two gears and you are all set....it's good to rev it to redline.... after it's warmed up good of course. All the fun in a rotary are in the high RPMS!

I think that you need to express this a little better. Are you saying that when you turn the car on cold, then move the selector to drive, hit the accelerator, nothing happens, as in the car won't move? Will it rev up, does it stall? Does the car move at all when placed into drive?

Hearing your issue the way that I heard it, it sounds less like an engine problem and more like a transmission problem, but it could be a low engine power problem. Need a better explanation of the problem.

I'm thinking of buying an 04 Rx8. The test drive was great... there is some vibration from the rear left tailpipe while idling in drive, is that a sign of low compression?

I don't think is a sign of low compression. Is your engine vibrating when in idle? Check your tailpipe, it might be loose.

A number displayed on a gauge connected to the engine, which is less than the number stated in the service manual, is a sign of low compression.

(Can you figure out what I am trying to tell you?)

No the engine doesn't vibrate any more than an engine does while running, the vibrations aren't coming from the front nor does the engine visibly vibrate. While the car was parked in idle I walked to the back and listened at the tailpipe. Thanks for the input, but the more I go over it in my head the more it seems like the tailpipe was just rattling around in the fender housing.

Search FTW, although I almost feel like a wiki system might be useful for the "one great post" idea. Anyway, ya pays your money, ya takes your chances!

I just got my RX8 and when it's on and running it's great. Power seems to be there, idle is just fine. i hear nothing strange from the engine, but the start up is slow as hell. I'm going to check this starter gunk build up issue tomorrow and see if that is it. it does take about 2 seconds for it to start on a cold. about 3 maybe 4 on warm.

Low Compression

I have the same problem for me necessary doesn't take very looong to start like he said but it takes like 3 or 4 seconds to start. My 8 idles perfect just changed plug/wires and coils starter as well. I don't know if this is normal or not?
