hey guys i need a little help.

my wife drives a 02 civic si w/ 124k miles.

the idle has been acting a little weird, when you come to a stop or leave it out of gear while off the gas the idles would drop and the engine would vibrate pretty bad then go back up after a few seconds.

today while headed out of town in the civic the car stalled after pushing the clutch in after coming off the highway. when i rolled into a gas station and tried to restart it thats when it got bad.. the idle was crazy jumping from 0-1000 and would only stay running if i held the gas down.. i did not hear and ticking or knocking so i drove it home ( having to stay on the gas when i came to a stop) on the way home i pulled into advanced and used their scan tool. i got these codes..

1) camshaft positioning sensor A
2) 02 sensor bank 1 sensor 2
3) somthing about timing being too advanced
4) cyl 1-4 missfires
5) random missfires

( i wrote the codes down but lost them)

while coming home i noticed it smelled like a lot of unburned gas was coming out the exhaust..i purchased some new NGK's and replaced them when i got home.. the old ones where VERY black.. It did stay running at idle after the new plugs where installed but still bounced all over and vibrated real bad. I then pulled the new plugs back out.. and they where very black after only having it running for about 5 min. also the car has lost power going through the gears.. you have to keep on the gas pretty hard to keep up with traffic..

the car is all stock no aftermarket adjustments or parts..
does anyone know what i might try to get it fixed?

 

sounded like IACV valve till i saw codes. I would definitely start with cam sensors maybe even crank. I know it doesn't list crank sensor but also a major factor in timing.

 

i wouldnt do anything till i have PID Data then i can run diag PID data shows what sensor is working correctly. You get this data when the car is on using the scan tool that will allow u to of course. hope u get this fix. this is how most technician start there diag in this case

 

PIDs are only useful for technicians and even then most techs dont know what they're looking at. OP your troubles seem to be a little too much for the DIY'er. i would take it too a shop and stop driving it until then. These are interference engines and you may damage it.

 

i bet the chain is really close to jumping i love k owners who think hey ill never have to replace it well truth is they all stretch and id just do it somewhere in the 100 to 150 k range depending on how well you paid attention to your oil change timing and how you drive it

 

And how many K series chains have you seen stretched. How often should the oil be changed??

 

just did one today on a car with 85k on it and i still believe in every three thousand and if you track the car change it before you go along with the tranny fluid

 

So 1 out of how many K series that you have encountered that were stretched?? What basis do you have for changing your oil every 3 thousand miles??

 

simmer down now.

 

Also, not strictly by the mileage only, other factors need to be considered as well...

 

if you keep up with your routine maintenence and dont you run your oil level low, your timing chain should last the life of your engine. its not just going to strech out and be a problem because you have a ton of miles.. the tensioner allows for some difference so you really have to be doing something wrong to strech it to a point where it becomes a problem. if your timing chain was strreched at 85k or even 185k you have other issuses.

 

exactly. Some sense exists in the world still...

 

wow spoken like a true fool what would you consider the life of the engine when the chain or tensioner brakes you ever see a chain out of the car and how small it is i doubt it because its good for the life of the car. considering when doing valve adjustments for people i find that the tensioner cant hold the cam timing spot on like a new chain can but im sure you know way more then me im just certified by honda to do the job

 

its a easy job to do can do it in your drive way all you need is a seven dollar honda tool to hold the cams in place so why would you risk having a slide brake when it gets old and brittle or tensioner fail but if you want to be cheep put new valves in it along with the chain sounds like a cheaper fix then maintaining your car

 

OP, a quick removal of the valve cover and the chain guide on the cam cap (two 12mm bolt/studs) and rotation of the crank to TDC will let you know if the chain is in terrible shape or not. You can check the amount of play in the chain between the gears and see where the cam triggers on the opposite end of the camshafts are lined up at. If it does happen to be mechanical timing related, expect to replace the chain and tensioner just to be sure.

Or, you can use a friend and two wrenches that you already have and save the $7.

Regardless, get off your high horse, while I agree that chains def need replaced (not as often as belts obviously), I've probably done more timing chains on K-series than you and I'm not even a tech. So chill.

 

well its not a pissing match im well over 30, wasnt talking to you and i said to remove valve cover thing just like you did so what did you add to this again oh nothing thats right

 

oh and when do them do you replace the vtc or not bet you don't hack run along shade tree dont you have a car to go dump on some ebay specails

 

Youre a tool, go away. Im an ASE certified L1 technican as well as a graduate of the PACT program. Ive been working on Hondas/ Acuras among other makes of cars for over 15 years. Youre a parts swapper. Thats why you believe in 3 k oil changes because the innovations in the industry have passed you by. Nothing but a grease monkey. You do one K series timing chain and you think you know it all. Chain stretch is very minimal .Cars have had timing chains for years and years. Its new to Honda so its new to you. You dont know **** about Timing chains. Chain strectch is very mininmal and rarely happens. Run along now son grown folk are talking in this thread.

 

wow thats i went to uti 3rd im my class been when honda for 8 year thats honda only not even at the dealership did that for 5 now its a honda only private shop with all the dealer equipment i have 4 bays all to myself in a 12 bay shop how many do you have oh wow one keep talking idiot ase dosent mean **** anymore talk about outdated im sure you can fix a astro van better then me good with that oh and timing chains have been around forever one bmw had a slide brake and took out the valves but i know nothing run along

 

"Well over 30" and you bicker online and can't type in proper grammatical English. Good job, man. Keep up the great work. Regardless, I know you weren't talking to me (I wasn't even in the thread until now), but you were being an *** to people that you didn't need to be an *** to. So I intervened. It's as simple as that.

asnboi512, any updates?

 

sorry, but you lost me after "wow"..., I'd love to hear your side of story.

 

Engrish?? UTI is the laughingstock of the industry. I wouldnt bother telling people I went there if I were you. ASE's mean nothing?? So then you must have them all,huh?? Pretty easy for a stud like you right?? I have a hard time believing an individual is capable of properly repairing a vehicle when he can barely read and write. Back yard sheneigans will only get you so far.

 

im so glad you spent your nights at your local middle school getting your ase certification congrats on that im sure that patches running up and down both sleeves of your jacket make you think you know what your doing enjoy finding a place to put all the ase study guides that you had to use to figure out what tech A and tech B are trying to do

 

im a honda tech ask me what i think...

 

I enjoy the money these ASE patches bring me. While youre slaving away in 4 bays i only need 2 to make twice the money you do. All because of my ASE patches. Work smarter, not harder son. The K series engine has been out for 8 years now. 1000's of k series engines are approaching the 150k mile mark. And very few if any of them need the chain R and R'ed.
