Check your bank 2 plugs for colour (do they look hot like they running hot ). Check you EGR Exhaust Gas Recirculation valve (looks like a 80mm diameter spaceship with a vacuum line to the top of it) If this remains closed the engine runs very hot and causes misfire. Possible causes are EGR not opening are 1) perforated diaphragm 2) encrusted valve stem 3) clogged exhaust gas feed pipe. A quick check for function: run the engine and remove the vacuum tube. The engine note should change as the tube is connected and then disconnected. Also pushing on the underside of the EGR with your fingers to lift the diaphragm to open the valve should also result in change in engine note. If its not working just disassemble the EGR and clean with carb cleaning spray, also clean the exhaust gas feed pipe likewise.

P0300 code silverado 1500 4.8v8 engine multi mist fire


more than one cylinder is without spark

check coil or coil packs... contacts .. corrosoion
leads
plug itself

Code P0300 is a code that is generated when your engine has a misfire that is not related to only one cylinder. Sometimes this code will be set in addition to other codes such as P0301 which means that there is a misfire on cylinder 1 (cylinder 1 is the number one cylinder when looking at the firing order.

2004 Chevy Trailblazer misfire with codes P0300 and P0410


DO NOT go back to this ripoff artist, he either doesn't know what he doing or is taking you for a ride.
Misfires are usually caused by bad spark plugs or coil packs. Find another mechanic.

Have code p0300 active just replaced fuel pump, all spark plugs, wires, cap, and rotor, engine back fires, and has explosion in the air filter area


Code p0300 is multi- misfires [ any number of the cyinders ]. Sometimes when a fuel pump is replaced, the system will have air inside and will mis & backfire untill the air is cleared back thru the return line, or blead out the test port. This will set the p0300 code. It's rare to have a backfire bad enough to have an explosion, bleed the lines thru the test port untill you see no more bubbles comming out.

PO300 code. 3.4L 98 Chevy blazer. (random misfire). this happens at high speeds 16000 rpms and higher. after the engine is warm it is more noticeable and misses at idling speeds. if i take it higher than...


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. it could be any of the following 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
  • also
  • 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.

I keep getting a P0300 diagnostic code on my 1996 chevy corsica what could be the cause for this


its a random misfire if it had a number at end instead of 0 e.i. 1 that would indicate number 1 cylinder misfired/ but 300 with no other codes can be multi reasons check spark plugs and wires--coils--clogged injectors--fuel filter--fuel pump--bag gas(water) partial clog cat converter these are a few but best to start with plugs &wires
