2004 Isuzu Rodeo S-3.5L/6VE1;Misfiring@#2-code:P0302

Possible blown headgasket since the entire bank is misfiring. Have a compression test done on it.

Codes p0300 random misfire, p0302-0304 misfire cylinder 2-4. P0133 o2 circuit slow response bank 1 sensor 1. P1176, P1300, P1580, P1543, B0423 r make specific which you didn't say this would cause the problems you are having.

The P0302 code means that the cylinder 2 is misfiring or is randomly misfiring. Start by checking for intake leaks an if no leaks are found the next step is to replace the spark plugs on cylinder 2. If the problem persist more tests needs to be done to diagnose problem, see "Possible Causes"
- Faulty spark plug 2
- Clogged or faulty fuel injector 2
- Faulty ignition coil 2
- Fuel injector 2 harness is open or shorted
- Fuel injector 2 circuit poor electrical connection
- Ignition coil 2 harness is open or shorted
- Ignition coil 2 circuit poor electrical connection
- Insufficient cylinder 2 compression
- Incorrect fuel pressure
- Intake air leak

more than likely your spark plugs they should be changed every 60,000km

you could have a vacuum leak somewhere. check the fuel filter, it may be going bad. and battery. all these will cause a random misfire code. as well as your plug wires. intake air leak, spray carb cleaner around intake manifold while engine is running if the idle changes, then you have a leak. Good-day! but check for vacuum leak first! a vacuum leak will cause engine to hesitate and lose power.

check for 2 things, CTS, and the injector, reason, if the injector is clogged or misfiring, you can still have and issue, i`m a mobile mechanic, if you`re in the long beach area email me back

P0300 - Random multiple cylinder misfire
P0301 , 302 and 304 - Cyliners 1, 2 and 4 misfire
P0351 - Ignition coil A primary/secondary circuit malfunction
P0354 - Ignition coil D primary/secondary circuit malfunction

Cylinder 2 Misfire Detected po302 . Evaporative Emission Control System po440 The last digit on a misfire code indicates the cylinder number. A code P0302, for example, would tell you cylinder #2 is misfiring. Chances are the misfire is due to a weak ignition coil. Did you change the pcv valve? Remember to put the o-ring on the new one or this problem will happen.

most likely the plugs and wires need changed.
