SOURCE: Misfire in Cylinder 1,2,3,5,6 of my 2000 Acura Tl

you may have a faulty crankshaft position sensor this is what controls the firing of the plugs. you may also have corrosion on the plug for the coil pack causing multiple misfires

SOURCE: 2005 Acura TSX Navigation Unit cant read disk

Alot of cars loose the navigation when the battery goes dead. I see your cars battery could be at the end of its life.

If this is the case you will need the dealer to reprogram the unit.

Misfiring code po1399 cylinder 3 and 4


On most Honda's when you get a misfire happening across the whole engine like that there are a few likely issues. the ignition coil if it's a single coil style or the connector at the distributor. They also have some issues with EGR's and plugged ports which can mess with the fuel trim numbers. It's important to check the fuel pressure and if possible a timing offset spec from the scanner whenever you're dealing with misfires on any vehicles Honda or not and determine correct pressure and flow whenever possible.


Hope this helps.

Terraza P0303 Code. What's most likely cause? Injector, spark plug, wires or any of the above?


Might be dirty injector or burned valve. Check the connector on the injector. If good, run a compression test on all cylinders. If compression is significantly lower on #3, the head will have to come off. If compression is good, pull up the injector rail with injectors and wiring attached. Watch the injectors spray as someone cranks the engine.

Terraza P0303 Code. What's most likely cause? Injector, spark plug, wires or any of the above?


Without testing we would be just guessing . Hook up a spark tester to # 3 cylinder plug wire , is there spark ? Is the fuel injector for that cylinder squirting fuel , they make tools for checking this . Hook up a fuel pressure gauge an fire the injector , does fuel pressure drop. Could be a engine mechanical problem , compression test . Videos on youtube showing how to do these test's .

Kinda putters then engine light came on and its giving me a code p0303


p0303 is a mutible engine misfire on number 3 cylinder. the best fix,

A code P0303 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
  • but first of all check the wires and sparkplugs first!

Cylinder Misfires


It could be your spark plugs or a coil. To see if it's a coil move the coil from #5 to #6 the miss will change to that cylinder with code p0306 and change #1 to #3 and see if it changes to p0303. If it does replace all the coils. You change all coil because if one or two go you know the rest are not far behind
