You either have a bad plug wire or have cracked one of the new plugs while installing them. Try watching under the hood while someone else accelerates the engine to locate the noise.
Good luck dont forget to rate.

SOURCE: temperature gauge rises when idling

First check that your fans are operating and coolant level is full. If they are, check that there are no leaves etc stuck betweren the radiator and the AC condenser.Last option is a bit more expensive...radiator may be partially obstructed internally (would need flush or replacement)
Egg smell brings me to another potential problem if converter is partially plugged it will raise engine temp as well...the rubber smell is oil residue on block getting hotter than normal and evaporating.
If you work on this yourself ask any techinical questions you have along the way and I'll try to help. Otherwise get the car to a shop asap...overheating in any form can severely damage your engine.
Good luck!!

SOURCE: 1997 Tahoe wont start, has spark, and fuel pump works

Your Tahoe does have a vacuum line connection to the regulator. It's also possible the regulator itself is bad,

White smoke cylinder misfire and smell of gas on my Volvo 2002 v70xc


4 cylinder? Blown head gasket. 6 cylinder, look to the throttle body. It has coolant lines on it, it can and will corrode though the throttle throwing coolant in the intake. 1 And 2 are the first to misfire. But usually have multiple misfires.

How to fix misfire cylinder # 6


DTC P0306 - Cylinder #6 Misfire Detected
A P0306 code means that the the car's computer has detected that one of the engine's cylinders is not firing properly. In this case it's cylinder #6.

Symptoms may include:

the engine may be harder to start
the engine may stumble / stumble, and/or hesitate
other symptoms may also be present


A code P0306 may mean that one or more of the following has happened:
Faulty spark plug or wire
Faulty coil (pack)
Faulty oxygen sensor(s)
Faulty fuel injector
Burned exhaust valve
Faulty catalytic converter(s)
Running out of fuel
Poor compression
Defective computer


About possible solutions, if there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.

If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs). Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.


Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Random misfire on 2004 chevy tahoe z71


Use some electrical spray cleaner or tuner cleaner and give mass air flow sensor a good cleaning. then try it. If that doesn't help, a fuel system pressure test may be smart to confirm proper pressure required is there. Low fuel pressure will cause multiple random misfire as well.

Egr valve for 1997 cheve Blazer code is 0300 misfireing what could be the trouble


usually this code is followed by another number 1-4 or 1-6 or 1-8 depending on how many cylinders your vehicle has ,, what the code you got is a basic P0300 Random/Multiple Cylinder Misfire Detected A code P0300 may mean that one or more of the following has happened:
  • Faulty spark plugs or wires
  • Faulty coil (pack)
  • Faulty oxygen sensor(s)
  • Faulty fuel injector(s)
  • Burned exhaust valve
  • Faulty catalytic converter(s)
  • Stuck/blocked EGR valve / passages
  • Faulty camshaft position sensor
  • Defective computer

If you smell rotten eggs in the exhaust, your cat converter needs to be replaced. I've also heard in other cases the problems were faulty fuel injectors.
    Random misfires that jump around from one cylinder to another (read: P030x codes) also will set a P0300 code. The underlying cause is often a lean fuel condition, which may be due to a vacuum leak in the intake manifold or unmetered air getting past the airflow sensor, or an EGR valve that is stuck ope

I have a 2005 chevy impala 3.4l v6. I am getting the code P0300 (multiple misfire).i recently changed the spark plugs/wires/coils and have checked all vacuum lines, but my car is still idling...


Basically this means that the the car's computer has detected that not all of the engine's cylinders are firing properly.
A P0300 diagnostic code indicates a random or multiple misfire. If the last digit is a number other than zero, it corresponds to the cylinder number that is misfiring. A P0302 code, for example, would tell you cylinder number two is misfiring. Unfortunately, a P0300 doesn't tell you specifically which cylinder(s) is/are mis-firing, nor why.
Symptoms Symptoms may include:
  • the engine may be harder to start
  • the engine may stumble / stumble, and/or hesitate
  • other symptoms may also be present
Causes A code P0300 may mean that one or more of the following has happened:
  • Faulty spark plugs or wires
  • Faulty coil (pack)
  • Faulty oxygen sensor(s)
  • Faulty fuel injector(s)
  • Burned exhaust valve
  • Faulty catalytic converter(s)
  • Stuck/blocked EGR valve / passages
  • Faulty camshaft position sensor (more than likely your culprit)
  • Defective computer

Getting gas smells and misfiring on a 2000 chevy venture. what might be the problem? was told not running on 2 of the 6 cylinders could that be the only problem? i am being told its something else


first off you have to fix the misfire problem before you can do anything else,as a misfire will cause a fuel smell because you have 2 cylinders acting like a raw fuel pump ,by the fuel entering the cylinder not burning a being pumped out unburned.so you have to find out why it is your six cylinder car is only running on 4 cylinders and repair the problem.then you can go from there if you have to,also you will have to change the oil as it will have fuel in the oil which thins out the oil to a point it does not do it`s job and could ignite in the oil pan causing other problems

96 lexus es 300 blinking check engine light


Hi there;

#4 Miss-fire. All the things you are saying make a lot of sense. When the light is blinking the cylinder is actualy misfiring, & the smell you are smelling is the fuel that is not burning in the engine burning in the exahst. This can cause a lot of damage to the exausht if it is not repaired..
There is still a couple of things that need to be checked, first he needs to check to see if it is possibly a fuel injector that is sticking. He can do this easily by moving the #4 injector to another cylinder & run the car. When it starts missfiring he will need to see if it is still #4 or if it is the cylinder that he moved the injector to. if it is the new cylinder it is obviously the injector, if it is still #4 he will need to look into the possibility of the EGR valve sticking open or some other issue to do with valve timing or low compression.
I hope this helps
Farrout!
