Hi, so I've been getting some violent misfires sometimes at low revs. Its like that for a couple of minutes at low revs then it runs fine. Pulled the fault code and it's error 21, P1320. Googled it and I read that the most likely cause is to do with coil packs. http://engine-codes.com/p1320_nissan.html


I don't think its the coils themselves because I had them replaced with JJRs just a few months ago when I had another error 21 and a misfiring engine. And its run perfectly since then up until a week ago. I didn't replace the spark plugs then, could it be those this time? The odometer reads 135000 and I don't know if the previous owner replaced the sparks at any time. I also read somewhere that sparks can go bad from being run with bad coil packs, and I was doing that for quite a while last time I got the error code.


Thanks

Over the last few days the misfires have stopped and the engine is running fine once again. The check engine light has also stopped turning on. Could the misfires have been caused by a bad batch of fuel or something?

So I had a huge misfire last night waiting at a red light immediately after exiting the motorway. The car was shaking like an old bus. The misfire continued until I put it in third gear at about 4000rpm, after which it stopped. There were no more misfires when I came to the next red light.


Last time I took the car in to service I was informed that the rocker cover gasket is leaking. It occured to me today after watching this video that leaking oil could be fouling the sparks, causing the misfires.




Has anybody ever had a misfire from oil leaking onto the sparks?

So I just got it back from the mechanics. Replaced the rocker cover gasket and got the sparks and coils cleaned. I didn't get to drive it far yet but so far so good, there was no misfiring at idle and I didn't lose power through the low-mid RPM ranges. The engine light is still on but I haven't yet connected the consult to get the code. I'm hoping the uncleared code is Error 14 Vehicle Speed Sensor since the speedo doesn't work. Hopefully the misfires stay away!


I was told that the PCV valve and hose need replacement. How difficult is it to replace it? I'm a total novice at anything mechanical but I would like to start learning, starting with replacing the PCV valve and hose.

    • LOL, when one "money pit" is never enough Noice, and excellent work mate
    • I have more than enough digging, laying blocks, moving gravel, airrating, feeding and top soiling the grass, and setting up the veggie gardens growing some seedlings,  and then removing all the unused rock to keep me busy for the next few months at least,  hopefully the rain stops soon so I can get a few hours in this arvo, but, before that Sunday is washing day, is every body happy, you bet your life we are Nice country road day drives are a day off whenever I'm muscle sore from all the landscaping at the moment, but, more epic multiple day drives will start once the majority of the big jobs outside are completed
    • I hear that would involve some nice country road drives into the hills for Mark...
    • I thought I'd come back and add something I JUST learned. A Toyota LandCruiser with a 1HZ, mates perfectly with a bottle of Nulon brake fluid. As in, it perfectly screws in. Great make shift funnel when you cut the bottom of it off. This may work for your Corolla.   Unfortunately, tipping a 10L drum is much harder than a 4 to 6L bottle, and they no longer include the easy pour tap which was just perfection to use previously.  
    • Guys since i bought r33 gts25t coupe 1994 automatic a/t(manual swap 350z gearbox)  all i got is problems, always problems. Lets start with that when i turn key into ignition(ON) fuel pump doesnt always works. Sometimes i have to turn key twice Off/on/off/on until it primes. Its new, dw300 - 340lph. My gearbox broke so i did gearbox swap, install different intake manifold, injectors and i take pipes. Car was sitting in garage for more than half a year. I did assembly all not that long ago and when i turn ignition cant hear prime. All of sudden it stopped working. Theres many videos on YouTube how to make relay mod on r33 straight from battery so i did and it doesnt work! 😰 30 - battery positive  87 - positive from fuel pump to relay 85, 86 - one of two wires from original fuel pump wires(light blue, grey) and it didn’t work. so I check on ignition and took original BLUE relays wires from trunk, next to fuses. (I believe it’s IGN+ and ECU pin 18. it didn’t work…  tried connecting (IGN+ from og relay) and (ECU 104 from 1of4 FPCM wires) to my new relay 85/86 and it didn’t work.  I unplug FPCM. Didn’t work. im thinking what’s wrong   fuel pump is working, if I leave IGN+ on 85 and 86 straight to ground it works but it’s just nonstop. Since it getting constant 12v after key in ON. light blue wire gives me 6-8v.  so how this should be connected? What causing ECU not giving — on pin? Or I did sth wrong and that’s why it doesn’t work? I need negative signal on ECU that control fuel pump. What this should be?
