It only seems to happen when I'm idling.

Had a CEL 41, replaced O2 sensor and it went away.

Replaced IACV, didn't help.

Replaced spark plugs (they were all black) and plug wires, still not fixed.

I'm going to replace the Cap and rotor next, any other suggestions? This is really getting on my nerves.

Another thing I forgot to mention was the RPMs seem to be steady (albeit a bit low) they drop when turning on lights, but it goes right back up to where it was.

Replace cap and rotor and have the battery and alternator tested.

Mario245

Replaced my battery a few days ago since it died cause I haven't been using or starting the car.

Mario245

Does it matter which car I get the cap/rotor from? Since I have a GSR head would I need to get it for a GSR?

Mario245

I'm pretty sure I'm running rich as well, my old plugs had a bunch of black carbon built up and they were fairly new (400-500ish miles)

injector could be stuck open!

Mario245

I've noticed a bit of build up around the outside of the injector for cylinder one, anyway to tell if its stuck open?

jake 92eg d16z6

my buddy has a crx and he had 3 stuck open only runnin on one cyl. then took it to get fixed and only one was stuck open and the car was runnin way rich and miss firing ill get a hold of him tomorrow and find out how you tell i never had the problem so i dunno

Mario245

Alright thanks, ordered a cap and rotor as well and they should be here sometime this week.

jake 92eg d16z6

my car is runnin rich also but not bad bad its not thinning out the oil just not the greatest tune but i really dont care

Mario245

Well it's not affecting performance in any way AFAIK, it's just a slight sputtering noise at idle (haven't driven it as much) and it stops for a bit when I turn the A/C on too.

Mario245

Here are what the old plugs looked like after 400-500 or so miles

Three out of the four plugs look in bad shape. I'd replace all because NGKs are pretty cheap.

Mario245

I've already replaced them with more NGKs

Mario245

Ok, quick question: Are B series dizzy caps and rotors interchangeable? I got a OBD2 Cap and Rotor and it won't fit on my OBD1 Dizzy. I'm returning it, I wanna get the right one this time lol.

Just thought I'd throw this in here as well, here are what the new plugs look like and all I've been doing is idling in my garage.

Is there any place I can get the spring thats on the ignition coil without having to buy a new one? I lost it when I accidentally hit it.

Mario245

Well I replaced the cap and rotor and ignition coil (since I lost the spring) and the sputtering noise is still there. I also did a compression test: Cyl1:230, Cyl2:220, Cyl3:220, Cyl4:220 (JDM B16A with GSR head) and this sputtering noise only happens when I'm sitting, the car drives fine.

I'm lost and have no idea what to check next.

Sounds like you may have a cylinder that is not firing when you are idling.

to identify this look at the engine mount on the side for any vibration. When all 4 cylinder are working there should be slim to none.

If it is vibrating start pulling out spark plugs to identify which one it is.

Your roote cause may be something else but this may help to identify the full symtoms.

Mario245

I believe I mentioned this before but it seems to stop for awhile if I turn the a/c on.

Mario245

Another thing, I noticed my temperature gauge doesn't seem to move even though the car is warmed up.

My oil also smells like gas too.


I'm about to just give up on this car, it's really getting on my last nerve. I haven't driven it since may.

EDIT: Tried raising the idle for the hell of it, idle didn't change at all.
