Thumbs up Engine Problems, if you know engines.. read

alright, well starting in january ive been getting CEL's and i go into honda and they say "misfiring" and then they say "we'll just reset it, maybe its bad gas... lemme know if it comes back on"


i go back 6 more times, same thing.

finally im pissed i go in today and they say "misfiring on all cylinders" then they say thats going tobe 60$ since we checked the OBD2, i tell them no thanx on the 60$ if ida known that ida just told you what it was.

so then they say "it seems like your valves might be too tight and causing he misfires", thats going to be a couple hours at least of work.

i then go off on them about how the ONE thing warranty doesnt cover is obv the problem and they agree to comp the valve adjustment.

the car is waiting there overnight now because valve adjust has to be done when engine is cold..

i know they are going to throw more BS at me so im wondering what do you guys think it is so i can go in and have some ideas of my own when they try and lie to me and tell me its not covered.

my close friend is now telling me that when i thought it was clicking, was valve adjustment needed, i didnt get so then after a while it started to create a misfire which could very well be the problem and hopefully they solve. but other than valve adjustment what could cure a misfire. or whats causing it


one friend says bad coil packs,
another says bad plugs.

whats your take on the situation because i surely cant leave it up to honda guys to tell me the truth

i figure worst case tomorrow when they try and deny this/that under warranty ill just call the newspaper and have a great article about how warranty's mean nothing anymore (brand new dealer, hasnt even had grand opening yet, they might stop bullshtting me then)

has the car ever had a valve adjustment?
...and they make you wait overnight for the adjustment?! ...that's odd.
How many miles on the car? You may need new plugs.

see what happens after the adjustment

Out of approximately 350 S2000s, I have NEVER found a single tight valve.

Unless the valves were tampered with before and done improperly, that is not the problem.

44k miles,

they said valve adjust has to be done cold because heated up they expand or something.

what would you think the problem would be if after they adjust the valves everything is the same?

I think you'll get your answer tomorrow, if the car is till throwing the code after they "fix" what they think is a valve problem, they'll figure it out.

every mechanic has their own little "lingo" it's possible the guy said your valves are "tight" and meant they need to be adjusted... and your problem may very well be fixed.

I'm curious, definately give an update tomorrow.

I know "E-Brake" had a problem with aftermarket plugs that caused misfire and later ended up blowing his motor. He ended up having it replaced by Honda ...it could be a plug problem


I'm betting it's the valve adjustment.
If not, clean your injectors and replace your plugs.
From there, probably coil packs (but I doubt it will get that far)

i decided about 5 mins ago.regardless of what the guys say im trading in for G35coupe tomorrow... as long as they still have it by thursday when i have time to gut the s2k and bring it by to trade in.

found a blue/black int. 04 manual/navi/brembo coupe. 24k

i figure theyll owball me on the s2k and ill lowball them on the G35 so the difference regardless will stay at around 6k.

we'll see..

valve adjustment done, didnt fix anything...... now they wanna change the spark plugs out (obviously not covered under warranty)



so im thinking....... if the motor blows.. thats covered under warranty... but the plugs arent so i might as well let it blow.


i was going to trade it in for a G35 today but they sold the one i wanted... just not my week

Well if you don't properly maintain your car they CAN void your warranty.

So if your engine blows and the new spark plugs would have prevented that (as unlikely or likely as that may be), they will not do any warranty work on your car because it did not have proper maintenance done.
