Check your fuel pressure, and or injectors. You may have too much fuel getting into the engine causing it to burn rich and overheat the converters.

SOURCE: Truck not firing properly front coil pack not firing at all.

if this truck has an o2 sensor i would replace that and also make sure the cat-converter is not plugged,this would give you your powerloss and egr code,next is your coil,this may be caused by the computer or your crank sensor,look at the tone ring that the crank sensor uses and make sure its not missing teeth or broken,also check all your fuses.

My 2007 Chevy Cobalt engine light blinks and the motor starts to miss. But the OBD code reader says there is a link error. I changed the spark plugs but it's still missing from time to time. What can I do?


Could be a bad coil but usually blinking is emission related, catalytic converter? Recommend you take that to a certified Chevy mechanic for a diagnostic, it's not that expensive.

It will take a while to get rid of all the oil that leaked into the spark plug hole. Take it apart again and recheck.

My 2002 dodge stratus is acting like it is missing out or spuddering. I have changed the spark plugs and after doing so it ran really well for awhile then started doing the same thing again?


You may have a bad coil pack. They are located on top of the spark plugs. If a coil pack is bad then if will miss as well as you could loose gas milage and performance.

Car is missing and cutting out. Also It has no power.


You may have bumped a wire or vacuum hose causing your problem. Look in the areas where the plugs and wires are and check all connections and hoses. Look for missing or damaged wires and hoses. Be sure your routing of plug wires is correct.

1996 Chevy Cavalier not firing on 1 & 4


The engine computer can tell the ignition module to change the timing but it doesn't control the spark , the module does. So if you are loosing spark on 1 and 4 it is not the engine computer or the wiring going to it. The problem has to be a plug, plug wire , coil, or ignition module. The reason you loose 1 and 4 is because they are both on the same coil. If the plugs and wires have lots of miles on them, I would change them first. DIS system have to fire what is called a waste spark, if you have a plug or wire with high resistance it will cause a miss on the cylinder it shares a coil with. If that doesn't help then I would switch the coils and see if the miss moves to 2 and 3.
