avs0730 · 08-19-2008, 08:02 PM

i finshing my s14 sr swap in my 97 s14 and i having some issues. first the car has a miss sound like a wrx. i pin point that the 4th coilpack is not firing right weak signal. i have power to the igntior but weak signal coming out of the 4 th coil. so my friend came by with his s14 with s14sr swap and i check the ignitor and it sound like mine. then i connect his back up and when he started up again he still having the same problem.

i check all his coil and all has power, i check the injectors and it has power. need help. any positive feedback will helpful

wish i could help, good luck.

jbuckley · 08-19-2008, 08:09 PM

100% sure its electrical?

could it be a vacuum leak or something? all plugs are plugged in etc?

aNskY · 08-19-2008, 08:11 PM

check your injector o-rings

avs0730 · 08-19-2008, 08:21 PM

my friends car ran fine before i disconnect the ignitor

i like the sound of the WRX haha.... try replacing the coil pack

lilpiton · 08-19-2008, 08:59 PM

check your compression ... check your injectors

ILoveMyRHS13 · 08-19-2008, 09:01 PM

My KA24E sounded like one but thats a whole different ball game... Oddly enough I just needed to add oil... Sounds REALLY dumb but check your oil.

flip3d · 08-19-2008, 09:04 PM

maybe someone swapped the motor with an EJ

is right.... so when you put his car back together he started having the same problem?

Try checking the gapping on the spark plugs!!

maybe headgasket? or compression is jacked

Sileighty_85 · 08-19-2008, 11:21 PM

Check fuel injector clips and spark

Isolate the dead cylinder by pulling Coil packs one by one

When unplugging the coil if no change occurs then thats your problem cylinder

If you find the problem coil, swap it in to another cylinder if it follows then that coil pack is bad

issac · 08-19-2008, 11:54 PM

the only time mine sounded like that, My turbo to manifold was loose. I replaced the gasket and tightened it up and BAM.

Slammed180 · 08-19-2008, 11:59 PM

My girlfriends R32 had this problem a couple of times. Turned out to be 2 separate coilpacks had bunked out on her.

Lol last time my car sounded like a WRX i blew a ring. Doesnt seen to be the case here but good luck!

i check my and his compression and it is 120 on both cars i check the injectors today

MADE · 08-20-2008, 03:35 AM

Once you checked all that and if you have no progress try swapping the ECU or check the signal to that injector. I assume you already swapped the plugs.

120??!! Normal is 150ish

Your compression is Wayyyy low minimum is like 129psi

did you pull all the plugs and crank the engine WOT until the needle stops rising??

If you did
drop a little bit of oil in the cylinders if compression improves then your Rings are bad

yes i check the plugs and they are burning nice no liquid on the plugs(meaning gas or oil)
i also swapped ecu and disconnect the battery and nothing. same thing

well i loose the plugs but didnt take them out well i say 120 but some are 124-129

avs0730 · 08-20-2008, 02:56 PM

could it be the o2 sensor

Croan · 08-20-2008, 05:38 PM

its a miss fire. most likely a bad spark plug that is fould

zugoi · 08-20-2008, 06:01 PM

so if i understand this correctly. After you swapped out the coilpack for your friends car(which was runing fine) and put it back, his car has the same problem and sounds like a wrx now. So both your cars have the same problem. You should double check the connector for the coilpack. Maybe when you pulled out the connector for your car or your friends, you messed up the connector. I had the same problem when i was working on a limo. The connector got power but it was'nt grounded correctly so everytime i put a new coilpack in, it shorted out and fried the coilpack. So i would double check the connector to make sure its not shorted out. This could be the reason your friends car is not running right either if you fried his coilpack. Im pretty sure once you find the short your problems will be gone. My bet is the connector that plugs into the coilpack,just replace it. Good luck.

Ceepo · 08-20-2008, 06:19 PM

Sounds like it fried the coilpack as stated buy zugoi...

i swapped ignitor not coilpacks. tomorrow i going to change the spark plugs and see if it change anything. the connection are good on all three wire on each coil. thanks to all on the postive feedback any more will be great

avs0730 · 08-21-2008, 05:20 PM

i found the problem the one wire that was extended came loose going into the ignitor. i check the the coil for power and i thought i did but there are 3 black wire on #1 cyl. so i soildered it and it is fix now

. thanks to all for info
