    what motor is in . lets do a test on the injectors.. take out any injector and swap it with number injectorand put number 3 where you took the other out. please be careful of the o rings.. start is and check leaks and drive it,and if the light come back on ,and if it is now the cylinder that you put the number 3 in..then you have a bad injector. but if it is still coming up with cylinder 3 then you have a stuck valve.iI am self employed,and I do a lot of head gaskets and motor rebuilds. if you want add me on facebook send you my link, when you are on my page just comment on it and I will add you.maybe easy to go through your problem thank you ted

SOURCE: #5 cylinder misfire

I have a corolla and had #4 cylinder misfire also diagnosed at autozone. After changing the spark plugs, problem persisted, along with the same error code, so they recommended changing the spark plug wires, and that is what fixed it. I would have changed the rotor cap too, but was low on dough. Glad that was not the problem.

97 acura 2.2 cl engine light p0302 code

A P0302 is indicating that cylinder # 2 is misfiring...Cylinder # 2 is the second plug counting from the front to rear of engine...Main causes for misfire are: defective spark plug, spark plug wire...When was last time plugs were changed? if it has been awhile I would suggest changing them...Also the spark plug wires should be replaced...Changing one plug and/or one wire isn't a good idea; change them all...Plugs cost two or three dollars apiece and a set of wires around $15...Standard motor products wire set # 4717...Spark plugs; Bosch platinum gaped at .044

Hooked up computer to dodge ram 1500 4.7 liter magnum code came up p300 p301 what does this mean

P0300 is the random misfire code. P0301 is the misfire code for Cylinder #1. When was your last tune up? non platinum spark plugs should be replaced around 30-60k along with the wires. With platinum plugs that extends out to 100k. I would try a tune up first plugs and wires. Reasonably cheap fix that is a prevenitive maintenace item anyways. If you have just recently had a tune up or it does not solve your problem you most likely have a bad coil pack on cylinder#1.

Hope This Helps.

I have a 2002 TrailBlazer with the straight 6,diognostic check said #3 cylinder was dead or misfiring, also map sensor showed up. #3 cylinder was misfiring, so to test the coil pack I swapped #3 coil pack...

did you replace only one spark plug? that can cause issues because of differences in resistances between cylinders. also, did the map code stay off after replacing

P301 Code on 2001 Ford Taurus SOHC (not FFL) with 253K miles. Replaced plugs and wires with Bosch Platinum +4 plugs and Motorcraft wire set. P301 returned almost immediately. Engine performance extremely...

Coil pack should in the front top of motor, with engine running remove one spark plug wire at a time from coil pack ( careful not to get shock ) they should all have spark, if one don't replace coil pack.

ODB code P0303, cylinder 3 misfire

Replace Plugs / Wire (or Coil #3 if it's coil on plug). DO NOT USE Auto Lite Platinum plugs, use factory VW NGK plugs. Otherwise it'll run like ****.

96 grand am pop under accelation

Which engine 2.4 Twin Cam or 3.4 V6? The 4 cylinder engine is based on the old Quad4 and I would guess it's either running lean (weak fuel pump) or it's misfiring and you need to replace the spark plugs. Use only AC Delco platinum plugs or it will misfire ( other brands of platinum plugs can cause misfire, especially Bosch). If you have a 3.1 or 3.4 ltr V6 check for leaking intake manifold gaskets.

Replace spark plugs with plat core plug

Platinum plugs are NOT recommended for the Echo. The heat ranges are different. Put the right plugs in it (buy them from a Toyota dealer) and see if your problem vanishes. I get this quite a bit, customers put in new plugs, and it runs worse than it did before they changed the plugs. Note that ALL Toyota engines have a specific plug engineered for each engine. Platinums do not work unless the engine was designed for it. Same with iridium and NO Toyota runs well on the "split fire" plugs. If the problem persidts, change the coils around, see if the misfire "moves" to a new location, and you get a DTC P-0300, P-0301 and P-0302. If so, your coil pack may have failed, BUT, do the plugs first.

Cylinder 3 misfire

Make sure you're using the recommended spark plugs. When my car did that, I had put Bosch Platinum Plus-4 plugs in and got that same problem. Turns out the plugs are too hot and cause it to fire prematurely and kick the misfire code.
