Ka24de-t Severe 2 cyl MisfirePLEASE HELP LOL

whats up guys my 96 s14 is misfiring cyl 1 and 2 and I can not for the life of me figure it out. I was on my way to work when the car sputtered and died when I was going about 60 mph. It felt like I just shut the ignition off in gear and I just rolled in gear to a stop. I then tried to start the car and I wouldn't start at all. Crank but no fire. I went back to the car a few hours later to get it off the side of the road and when I tried to start it, it started right up and was only running on 2 cylinders. I realized when I got home my fender harness was torn. I fixed all wires very carefully and it still didn't fix the misfire. I have spark. I have compression. I have fuel running to the injector. my distributer is good. my maf is good. my coolant temp sensor is good. my 02 is good I switched the injectors around from a good cylinder to a dead one and nothing changed the same cylinders were still missing. I disconnected the battery and computer. I checked all grounds.. im stumped please help me

Try changing around the spark plugs. Or just change them out.
Is there any burning or carbon tracks on the plugs or boots?
Spraying water onto the spark plug wires with a spritz bottle should help reveal any shorts in them.

If you check the plugs in the dead cylinders do they show evidence of fuel? If you listen to the injectors using a stethoscope or screwdriver can you hear them tick? If the injectors are not firing but you are sure the wiring is good the next place to look would be the ECU. You could try switching the wiring from a good injector to a dead one and see if that brings the cylinder back (injection timing will be way off while doing this so just test it for a short time at idle). Good luck.

I haven't actually pulled the plugs out yet haha. but I know there is spark there bc I took the wire for that plug and put it to the valve cover and saw it. but im going to change the plugs out tm, thanks bro

thanks you for the reply bro, I don't know how I could switch the injector clip from a good cylinder to another one bc of how little of play there is. but ill try to do that tm. and do you know off hand if there are any fuel system fuses that could be bad. or are there injector solenoids that could be bad or is the wiring for the injector harness straight from the computer? ive never had an issue figuring out a problem like this its so frustrating dude. thanks for your help again bro. I really appreciate it.

but im leaning towards more of a wiring and injection issue because it was so sudden the car cutting off.if it was a prob with the plugs fouling it would be gradual no? let alone 2 cyl at once lol

Something you can do that will definitely nail down that it's a fuel issue is pull out the fuel pump fuse and spray carb cleaner into the throttle body while someone else cranks the engine over for you. You'll have to spray quite a bit, but if it runs smooth you'll know where to look.
That said, it does indeed sound like a fuel issue.
Alternately, if you can get your hands on some noid lights, you could check to see if you have injector pulse at the cylinders that don't seem to be firing.
One more thought:
If it is a fuel issue like you suspect, do what jakemkz said, or you can follow the fsm in the electrical section, page 296 (or at least on the pdf version it is) called trouble diagnosis for non-dectable items.

thanks for the reply bro! that carb cleaner idea sounds really smart but I kept trying different things and gave up and dropped it off at my local shop. ill let you guys know what the final verdict is. thanks again for the help!!

As far as I am aware there is no fuse or relay that could fail and affect injectors 1 and 2 exclusively. However, the failure of components within the ECU could cause this behavior. The plugs usually have a story to tell regardless of the issue. Personally the first thing I would do is take a close look at all the plugs, inspecting the color, condition and checking for the presence of fuel or oil. The shop will be able to track down your issue, curious to hear what the results are.

What two cylinders are mis firing?

It can be a bad headgasket if they are right next to each other.

That's if you have checked your injectors and wires.

What was your compression on all cylinders?

I'm going to go ahead and tell you this right now.


Go to your local auto parts store, ready? Buy an MSD blaster 2 coil for $40-$45

Enjoy your working car again.


No need to thank me, It's only happened to me before.


Intermittent failure of the ignition coil is in direct relation to what you're experiencing. So If you're reading this I would highly suggest you get your ass to that shop and stop wasting your money!

I'm sorry, did I have to mention that you need to make 2 eyelets out of your stock ignition coil wiring?

It's not like it's a master technician level job.

So the shop gave up on the car so I got it home and I changed the Ecu. Car started right up and ran perfect....down the block. Then it started sputtering and died again. I tried to start it and it just cranked. Then after 15 mins it started again and ran perfect again. And then started sputtering under wot in neutral. Idk what's happening now lol

compression ran perfect all across the board. Now whats happening is I hear a buzzing sound from the ecu, and the rpm gauge is hopping around. the car will intermittently run flawless then itll start sputtering and the car will eventually cut out and not start back up..i wait a few mins.. car starts back up and runs mint. will run mint for a like 10 mins then start being hesitant and cut out again. is it possible I bought an effed up ecu? because the old ecu had 2 dead cylinders but the 2 that were running worked every time and the car drove compeletly normal except for the misfire? stumped again
