Try swapping the defective coil and see if the fault moves with the coil, if not you have defective circuits to the coil....When the scanner tells you a story, its only half the story....It reads faults in an entire circuit and it will identify that circuit, but maybe not the exact problem....Regards Johngee10

03 Zo6 p0300 Miss on cyl 7 & 8 replaced coils plugs still have misfire on 7 & 8

Code 300 is a random miss rather than a specific cylinder.
If you have a loss of power on one or more cylinders, it could be a fuel injector or mechanical problem in addition to spark.

2000 Nissan mis firing,, code reader shows codes: 0430; 0305; and 1320. Assuming its bank 2 cat convertor. Is this where i should start???

Your going to be spending plenty

You have to diagnose & correct your cylinder misfires
& make sure you have proper fuel control -- BEFORE--
you replace the Exhaust Converters & Oxygen Sensors,
ruined from the misfires

Properly diagnosed & everything done correctly,your looking
at about $1,000 & that is normal & those thing happen, on ALL
vehicle,even if you do all your own work

I would suggest you have a pro work on it,the best you can find

misfires are from coils , plugs , HT leads , and injectors and fuel pressure . If the head got that hot then it is possible that the injectors have an internal problem that shows when they get hot and the electronics breaks down.

Power loss and slight juking

Figure if you are running with 7 cylinders firing instead of all 8 you will have a power loss and jerking from the dead cylinder.

You could have a bad injector which a Noide tester will show or a Voltmeter will show on the power wire to #7 injector. For testing the injector, check if it has continuity so if it does get power, it will work.

Usually the Code will show from the Spark circuit failing. Either the plug, coil on plug or wiring can cause the misfire. On some engines access to the plugs is easier. You could change plug 7 to another cylinder or change coil on top to different cylinder without removing the plug. Clear the computer and see if defect moves from one cylinder to another.

If cylinder 7 is still bad with a different coil, you have eliminated the coil as a problem. Then its either the plug or the wire to it.

Car has bad miss and no power the check engine light is not on so i replaced plugs, wires and coil pack still has slight miss. what do i look for next.

You could have a dirty fuel injector.Just add some fuel injector cleaner into the fuel tank.Try not to get some cheap stuff.You can have the code checked to see what code is making the light come on.It could be a certain cylinder that is causing the problem and the code could help in finding what cylinder it is.Let me know if you need more help.Good luck.

What the miss there before you started replacing parts or did you replace some of them as maintenance items. Like the plugs. Possible that the parts store gave you one with a crack in it??? Also how about a vacuum leak at the intake gasket. You said you have compression. Have you tried checking running compression. A broken valve spring can cause good cranking compression, but cause no compression when it's running.

1987 cressida missing

Start with testing the injectors for pulse. Get a NOID light they sell the at almost any auto parts store remove in get plug from injector and plug the noid light into plug look for constant steady (pulse)lighting of noid light. Check all six injector on your strait 6. If all is good remove parke plug wire on at a time from cap and look for increased shaking and less when it replaced(Make sure to use wire puller with rubber insulation to avoid being zapped by spark from coil) Note cylinder with no difference or change when wire is removed. Those would be the problem cylinders. Then get a compression guage and check all cylinders for compression by removing spark plugs and attaching guage to each cylinders, make a not of each cylinder's reading. NOTE THEY SHOULD NOT BE MORE THAN 10 PSI difference in cylinders. Make note of low compression cylinders if any. If compression is good all around spark plugs are good, good ignition wires and you have good pulse pattern from you noid light. The only other problem is BAD INJECTORS and those would be the ones that didn't change when you took off the wires. I have work on these old cressida alot my self. Good Luck contact me if you need more help and if I solve your problem leave me a FIX-YA comment.
