Misfires So I have been dealing with some misfire codes on all cylinders recently. The car has always had some minor engine rough idle, although the rpms are steady. A new valve cover gasket was put in, a module for the spark plugs, the only other thing I can think of is the spark plugs. But the ones in there aren’t that bad. Never had a ck engine light come on till today. And sure enough it says misfire in 1,2,3,4. Any ideas?? Sent from my iPhone using Tapatalk |
Vacuum leak? Have a look at intake boots, Sap stuff, then hoses under intake manifold. Spraying brake cleaner in spots and listening for revving may work to find a leak too. |

Thanks man, will ck it out. I thought I did a good once over but will go back. Guess it was enough to throw a ck engine light. Sent from my iPhone using Tapatalk |
It could be a Camshaft Position Sensor. These tell the ECU when to fire the injectors and spark plugs in relation to where the intake camshaft is in the four cycles of engine operation. A bad one will not be able to time the components properly and eventually blow the engine because none of the parts are firing in the correct sequence. |

Did not think to ck that, of course I’m pretty new to these cars. Need to see what that looks like on line. Thx for the tip Sent from my iPhone using Tapatalk |
