WOW that is a lot of replacing for a 04.Have you ever tryed getting it checked for codes.Most MAF sensors need cleaning every time you replace the air filter.Did it every 3000 miles on my 04 2500HD or it would run bad.Think all you have to replace now is the O2 sensors and the crank position sensor,and may be the ignition moduel.HAHA well auto zone I hear will scan for free.Start there.Well once you get it scanned you can repost.Include engine size and miles.Well good luck.

Sounds like a problem with the fuel,contamination,use Lucas fuel treatment,and two bottles of HEET,these are the best fuel cleaners,and water dryer,it will most likely fix the problem.

I have a 1987 924s porsche..i had an intake leak at the intake manifold gasket but it ran pretty good considering for 20 thousand some odd miles with a little mis. So i replace the intake manifold gasket...


If you have spark and gas it should at least fire unless you don't have any compression. I would make sure that you have spark on all cylinders at the spark plugs.

My 2001 chevy venture van has a misfire as i drive what could be the problem


THESE VAN ARE KNOW FOR INTAKE GASKETS LEAKING INTERNALLY,CAUSING A MIS-FIRE. LOOK UNDER THROTTLE BODY AREA FOR COOLANT LAYING IN THE GULLY IF YOU SEE ANYTHING REPLACE INTAKE GASKETS FIRST. IF NOTHING IS LEAKING SPRAY SOME SOAPY WATER ON THE SPARK PLUG WIRES WHILE THE ENGINE IS RUNNING AND CHECK FOR ARCHING, IF ARCHING IS FOUND REPLACE THE PLUGS AND WIRES.

My chevy van failed smog and fault code p0300 stored for random misfire faults


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 may include:
  • the engine may be harder to start
  • the engine may stumble / stumble, and/or hesitate
  • other symptoms may also be present
CausesA 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
Possible SolutionsIf 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.
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 open.

2006 chevy express 2500 van with 4.8L idles really low, when you floor it it bogs down, after you let off the gas it dies, replaced the fuel pump already


Clean the throttle body with throttle body cleaner and make sure the air filter is not dirty or plugged.Also clean the mas air flow sensor with mass air flow sensor cleaner.Give this a try and let me know if it took care of your problems.Hope this helps.Good luck.

Iam having a miss fire every time i start my car on my 2001 chevy impala how do i set the timing with out taking it to the dealer i changed the plugs and the wiring and the pressure regulator still nothing...


The timing is not settable in a traditional sense of the days of distributors. The spark timing is controlled by the computer. If the computer is getting a bad signal, your spark timing will be off. Generally, a mis-fire isn't caused by bad spark timing. A sticking fuel injector, a bad or improperly seated spark plug wire, or a bad sensor will cause your mis-fires.
