Hey guys,
I'm ready to pull the trigger on an 07 honda s2000.
Everything is stock I believe, there is a little beep light that dings around 7k to warn me to shift. Not sure if that's stock.

Anyways, I inspected the car thoroughly an the only thing that was odd to me was when I start it it vibrates rather harsh.
Similar to poly bushings on a civic but only on startup. Idle and driving is fine

The car has 37k miles.

I did some googling, and only found this issue for shutting off the car

What do you guys think? Is this normal? Or is a mount bad?
let me know thanks

 

Vibration during start up...its gonna be very hard to help you with that, could you provide a vid? How long does that vibration last? Is it only when the car is cold started? Ask the previous owner/dealer about that shift light and vibration, or test drive another S and compare findings

 

Yea it is very hard to describe.
It's like a torque jolt right after the starter and the engine catches
It only lasts that brief 1-2 seconds when the engine fires
doesn't do it on cold idle
It would be hard to capture on video

 

found this guy, seems to be having my same experiance
http://www.s2ki.com/s2000/topic/7568...engine-starts/

edit, does it regardless if hot or cold start

 

is the car at a dealer? if its not used often the ecu might not be used to the current climate conditions so it dosent give the correct a/f and the motor feels like it stutters for a split second.

my best guess.

 

the car belongs to a used car dealer "owner"
he has 4 cars at his house, this is the one he doesn't drive.
The battery was dead when we got there
it's not a stutter I think, just a real strong rumble
I will go see it again tomorrow and try to get a better understanding

 

I was watching this video, because I would change the fluids as soon as I bought it.
The guys facial expression is exactly like mine when he starts it at 3:50
the start is very similar also

sounds normal to me. is this ur first fr? it could be just that ur not used to the engine torquing side to side instead of front to back

 

ok, 1. i didnt see any facial expression and 2. that guys an idiot for breaking plugs loose with a torque wrench...and i could have swore the last time i changed my diff fluid i used a 22mm wrench for the fill plug...sounded normal to me on start up as well

 

Yea, I never mentioned, this is my first s2000
^^ I think that's what's going on
at 3:50 the guy sorta looks up surprised
I will make sure I inspect t well before I buy

 

The video start up sound normal...

 

when ever you buy a used car, the very first thing to do is a compression test...

do that... regardless or any sounds/rattles/etc

 

The warning sound with light is a shift light. It was installed I guess as a backup to the tach, check this car out thoroughly by a trusted mechanic.

 

did he do a compression test?

and i can tell you anyone who installed a shift light+tech is a big red flag for a street racing tool

 

yea, I'm thinking about not buying it
I thought the shift light was stock but if it's not... I really dislike when electrical components of a car are touched

 

yea, no s2k came with a shift light stock

 

my 00 has a slight shudder in the shifter right when it starts up. not sure if its the same, only last like .5-1 second then its gone. i think its just the engine moving a bit

 

/it does have skunk2 springs

 

Before you buy it, Get a Compression Test done on it. All the cylinders should be within 10-15lbs of each other and have 160min. hopefully 200.
The 2000-2002 Yrs are prone to crack valve retainers, but regardless of the year, do a compression test first.

 

what type of coolant does an s2000 use?
The stuff was blue
Can I mix in 5050 antifreeze?

 

lol, so you bought it, and i take it you didn't do a comp test..
and it has a werid sound..

lol..

welcome to honda, for future stupid decisions, i suggest trusting your family's/cars safety to coilovers from taiwan, make sure you floor it a lot with bald tires..

can never hit enough telephone poles..

ohh and make sure you install the wrong size rims, performance is so 2010

*edit i like your crx, i hope your new investment doesn't crap out on you bro

 

if the owner reset the ECU recently the car may idle rough and have a small but noticeable feedback loop.

 

I have a pretty rough start up. vibiration goes away when the engine fully starts. slightly rough idle, shifter shakes a bit.. I'll take a vid later.
BTW I have an 05.
