You may have a broken con rod, remove the spak plug, insert a screwdriver in the plug hole, turn the engine over by hand and see if the screwdriver moves up or down with the piston or use a compression gauge to see if there is any compression on that cylinder, if there is no compression or the screwdriver doesnt move up and down then you need to remove the head to investigate the cause, drain the engine oil to see if there is any metal fragments in the oil and on the sump plug magnet, if there is you will have to replace the engine or have your engine reconditioned.

P0308 code intermintently pops up can i pass smog


  • Check Engine Lightflashing
  • Rough running, hesitation, and/or jerking when accelerating
  • In most cases, there are no adverse conditions noticed by the driver
  • In some cases, there may be performance problems, such as dying at stop signs or rough idling, hesitation, misfires or lack of power (especially during acceleration), and a decrease in fuel economy

I have a 2003 dodge durango 4.7 and it is overheating which i already r&r the thermostat. fixed the problem a lil but not 100%. also check engine light turned on for second time both same code P0308...


yes... overheating can cause issues in your piston/cylinder head. if your cylinder head is made from aluminum and not metal, overheating can cause cracks and bends in your cylinder head. if this cracks occur inside the combustion chamber, then proper compression cannot be attained. you need to rebore then resleeve your combustion chamber and change the pistons to fix this issue. this will also require resurfacing of cylinder head to ensure that it does not create leaks against crankcase.

Missing,viborating


Misfire could be a number of things:
a) spark plugs - change them if used over 15K miles - inspect/regap.
b) spark plug wires - change them if over 15K miles - inspect
c) ECM (electronic control module) - test with HEI (high energy ignition) tester.

The vibrating tells me that the engine is running on less than its normal compliment of cylinders - the shaking is produced by the imbalance caused in the engine by one (or more) cylinder(s)
not firing at all.

The "Check Engine" light probably is coming on due the the misfire condition. Go to Pep Boys or
Advance Auto Pats, where they'll tell you (free) your codes causing the "Check Engine' light to be
lit - the code coming from your truck's computer will probably be one or more of:
P0300 - Random/Multiple Cylinder misfire detected
P0301 - Cylinder 1 misfire detected
P0302 - Cylinder 2 misfire detected
P0303 - Cylinder 3 misfire detected
P0304 - Cylinder 4 misfire detected
P0305 - Cylinder 5 misfire detected
P0306 - Cylinder 6 misfire detected
P0307 - Cylinder 7 misfire detected
P0308 - Cylinder 8 misfire detected
P0313 - Misfire detected with low fuel

P0308 cylinder 8 misfire detected? How to repair?


Fuel injector cleaner commonly has a low success rate, and will not help if it's more than one cylinder that is missfiring. The fact that you have a "rattle" noise, leads me to beleive the engine is not receiving fuel on one or more cylidners. If it is all the cylinders, than the fuel pump may be the culprit, or the fuel pump circuit. But if only one cylidner is missfiring than it is a possibly an injector. A code P0300 refers to all cylinder missfires, and any code between P0301-P0308 distinugiushes a particular cylinder.

Misfiring
1- a general electrical tune-up (spark plugs, wire set, cap & rotor) is a basic start to cure this issue. Wiggle the dist shaft while you are in there, if you have one.
2- Then a good carbon cleaning / throttle-body cleaning.
3- Vacuum leaks at any of the hoses that connect to the Intake manifold; especially the MAP sensor connection.
4- If that does not help then the O2 sensor could be bad or drifting.
5- Funky coil/coil-packs
6- Theoretically a microsecond glitch in either the cam or crank shaft sensors would cause this, but I am not aware of this as a typical cause.
7- Lastly a funky PCM but again it is not common for this to cause miss-firing.

Note for the V8 then also:
a) bad erg valve (this dilutes the combustion gases and hence raises the combustion temp
b) a leaky plenum/Intake manifold gasket. Leaking Intake gasket symptoms

Also can check the TSB 18-48-98 Ignition System Cross Fire/Secondary Ignition Wire Induction (Complete Version )

Hope help with this (remember rated this). Good luck and have a nice day.
