okay engine light came back on again 2 days later.. haha my next step is to change the coil pack which cost alot.. should i replace only on the cylinder thats misfirin or should i just replace all four ignition coil packs.. and DUMB question but which one is cylinder 1? the one close to the firewall or on the radiator side? 1234 or 4321 ??

White Smoke

Don't go buying them just yet...
Try swapping them first from front to back, reset ECU and try again.
#1 is closest to the radiator, #4 closest to the firewall.

so after i swap em and if the CEL comes back on what should i do?get the code ?but i dont have the scanner thingy.. is it possible that it can be the gas cap also?the light is gettin annoyin kinda., hah

kaiba

You gotta change your oil every 1000miles.

White Smoke

What are you talking about?

It would be better if you could get the code, that way we know if cyl 1 was still misfiring. Autozone and other auto stores like it will pull the codes for you free of charge in case you didn't know.

If the problem follows the coil, then that is your problem. If not, I personally would do a compression test and if that was in check a valve adjustment would be in order.

ok finally got the ignition coil replaced 1 and 2.. check engine light comes back on every two days after its been reset.. can it be the gas cap? hammered!! map sensor? wth just barely got this car and its ****in up on me already. hahahahaa

Hey,

If you do that test where you wire up your obd2 port and read the code again you should get a different number according to the other cylinders misifiring you have to make sure that you swap a non misfiring cylinder coil pack or otherwise the test is useless... if so then the coil packs could be knackered...

Tuxedo Mask

If you did swap the coil packs you need to run the code to make sure that it is not the same cylinder misfiring. If it is the same cylinder misfiring then you could have a fuel injector problem.

If the misfire is in the other cylinder then you are golden because you just found out that it is obviously the coil pack.

You should also try cleaning the MAF Sensor as it can cause that problem.

Pull it out, spray it down. Plug it in. Done deal.

White Smoke

As I said before, run your new codes and see if the reported misfire followed the coil packs. If you bought new ones, well that was probably a waste of money.

I am getting to the point where I feel you need to do a valve adjustment, but before that go ahead and do the compression test.

White Smoke

And no it can't be the gas cap. I am pretty sure I have already told you everything you need to know in order to diagnose this problem here in the thread.

k 100/180psi across except on cylinder number 2 .. 50/140psi.. valve adjustment is the next step.. hopefully this time it'll fix the problem.. haha thanks white smoke ur a good helper.haha

White Smoke

Ouch!!! Yeah lets just pray your valves are way out of spec causing low compression in #2.

dc2_916

what else can it be if its not the valves not in spec? would it cost alot to fix or time to let my s2k go.

gooberwolf

White Smoke. You are good. Hope you keep the S2K.

ok the cel light just disappear by itself this mornin .. i just hop'd in the car start it up and the light didnt come on.. haha

I'm with White Smoke, hope it's a valve adjust issue. 40 psi difference is huge.

I would suggest putting a couple of drops of oil into cylinder 2 through the spark plug hole and redoing the compression test on that cylinder to see if your compression still comes out at 140 psi, or if it improves any. If it does, then the issues sits on the block side, if it's the same, then most likely the problem is the head side.

Good luck with your Gremlins.

did a valve adjustment new oil packs . cel is still on .. this time it blinks like 13 times then stays on. before it just stays on i start the car up.. need help plz

Try to find one of these for the S (unless it's the same)...

i did a diagnose before and they told me cylinder number 2 was low compression 50/140 .. all the other ones were 100/180 .. so i did a valve adjustment on it and it still pop'd up.. can it be one of the sensor just tweakin on me ? what should i replace first map sensor? o2 sensor?

i'm not a certified mechanic but you have bigger problems on your hands than a simple fix. you will need a rebuild...

sorry....

White Smoke

So after the valve adjustment your compression #'s were the same? If so the next step would be a leakdown test to find out where your losing your compression. This is probably getting to the point where it's over your head.

dc2_916

when i did the valve adjustment i adjusted cylinder number 2 only.. am i suppose to adjust all or just the one that need to be adjusted.. imma try replacin the fuel injectors also next..oh and is it possible to do a trade in with a CEL on from the dealers? like a cheaper car?

White Smoke

Don't waste your time replacing the injectors... You have low compression dude, that's your problem. You should have adjusted all the valves since you were in there. But since the #2 is the lowest then I guess just adjusting that one to see if it made a difference would be fine.

Next step is a leakdown test to find out where the compression loss is.

dc2_916

whats a leakdown test? and where can i get it done at?haha i need a dam new car now.. gsr bar'd ek?
