SOURCE: engine check light& error code p0301 on my 2003 rav 4,

Unless your computer in your car is faulty... the check engine light came on because it, or one of your vehicle's many sensors detected something within your vehicle was not operating under preset factory conditions. Fortunately, the error code that was extracted was indeed a cylinder # 1 misfire, which is fairly basic. Could be a bad spark plug, wire, etc. or you may have gotten some condensation inside the plug boot. Your mechanic did indeed clear the code, but drive it for awhile and see if it repeats. Normally with a cylinder misfire, you'll notice a small stutter when you accelerate or idle. If your Check Engine light returns, have the codes extracted once more. If the same cylinder is misfiring, have him replace the spark plug and wires.

SOURCE: Engine has miss-fire

First check spark plugs/wires/distributor cap (tune up). Also would be good idea to use fuel injector cleane and change fuel filter and O2 sensor.
Hope that helps
Good Luck

SOURCE: 02' Ford escape 6 cylinder:

Although you say you have coils misfiring, it sounds like you are not sure.

Trade the coils on cylinder 4 and 5 with coils on 2 and 3. Erase the codes and try to run the engine again. If the misfire code comes up on 2 and 3 this time, the coils are definitely the problem. If the code comes up for 4 and 5 again, there is something else besides the coils that is causing the misfire on those two cylinders.

Things to check: sticking or faulty EGR valve, vacuum leaks on intake manifold gasket near or between the runners for cylinders 4 and 5, clogged fuel injectors, a bad ground for the powertrain control module (PCM or computer), wiring problems to the coils.

2004 Ford Escape engine missfire


that sounds like those cylinders injectors might be the problem . When an injector over fuels or fails to supply fuel it would create a misfire just like if a plug or coil failed

How do I test for a bad coil in the coil pack, 2003 dodge caravan cylinder 4 misfire, done changed plugs wires seems to have made problem worse.


if you had a bad coil , it would affect two cylinders . you have what is referred to as waste spark ignition .if you have a four cylinder engine 1 & 3 - 2 & 4 are companion cylinders they share a coil . one cylinder is on the compression stroke an the other is on exhaust. how many miles on this vehicle ? i would do a compression test on that cylinder ! sounds like you have a engine mechanical problem ! how to perform compression test ericthecarguy

2000 Nissan mis firing,, code reader shows codes: 0430; 0305; and 1320. Assuming its bank 2 cat convertor. Is this where i should start???


Your going to be spending plenty

You have to diagnose & correct your cylinder misfires
& make sure you have proper fuel control -- BEFORE--
you replace the Exhaust Converters & Oxygen Sensors,
ruined from the misfires

Properly diagnosed & everything done correctly,your looking
at about $1,000 & that is normal & those thing happen, on ALL
vehicle,even if you do all your own work

I would suggest you have a pro work on it,the best you can find

Engine misfire on multiple cylinders


Do you have any codes besides P030x? Are you using the stock 1999 5.2 PCM? Do your short-term and long-term fuel trims show anything more than + or - 10? Are your O2 sensors showing normal voltages? You give a long (and impressive) list of modifications, but have you had diagnostics run through the PCM. It is what's controlling timing and fuel delivery. If the problem isn't mechanical it's got to be in the control. If you don't have the gear, invest in the services of an experienced ASE certified mechanic.

Coil issue


code p0301 and 302 refer to cylinder I and cylinder 2 misfire detected.--- causes--engine mechanical fault--wiring---ignition/ fuel system--injector--ECT/MAF sensor ---ECM I would have had a fuel pressure test done as miss fires from injectors not getting enough fuel would have been a better starting point
Run the fault codes again to see what else has happened.

Ford five hundred running on 5 cylinders


the code p 0302 refers to no 2 cylinder misfiring===causes --engine mechanical fault ---wiring--ignition / fuel system---injector--ECT/Maf sensor ---ECM
you state that the engine runs normally for several seconds so I would eliminate a mechanical fault at this stage
most misfires are from faulty injectors so reposition the injector to another cylinder and see if the miss moves along as well
if it doesn't move but stays at no 2 cylinder , then it could be a problem ECM
if you can get a substitute ECM of known good performance , swap it out and see if that fixes the fault

Miss in engine. DB2 codes indicated miss in


you may have a stuck injector (if your engine has an injector for each cylinder) ... if you place a stethoscope (or just a stick) on each injector you can hear them click as the engine runs .. if the one on cylinder 2 is stuck then it will stop clicking .. you can use some injector cleaner in your gas but the injector has to start working a little before it can do much good .. so if it works sometimes and not others then that might be worth a try .. if you cant get it working (wont click) then often you can pulse it into operation by very briefly touching 12volt across its coil .. if you keep the 12 volts on for too long it will damage the injector coil .. if you have only one injector then thats not your trouble ..
the cleaner usualy does the trick if you can get it to operate even for a short time .. you can also replace the injector if you determine that its bad ..

There is an a engine miss in my es 300 99 lexus


If you have coils and spark plugs then you don't have wires. From personal experience these car's misfire because of coils and BAD INJECTORS. If you replaces coils and sparks plugs you need to check injectors. Get a NOID light and check injectors pulse to make sure it good. First you must locate the cylinder that has the misfire/Missing,this can be done by using a computer/code scanner or if can be manually by disconnecting each coil and see when there is NO change in idling or shaking. What you are looking for is when you disconnect the Eugine should shake more and when you reconnect it would smooth en out. If any cylinder when disconnected the engine doesn't change that the one with the problem. Check again for spark and make sure it good. Then check that injector pulse plug off injector connector and connect it to NOID light you should get a constant flickering of NOID LIGHT. If you do then BINGO that injector is BAD. However I must say this test is on valued if you have performed a compression test on all cylinders to make sure there are no BAD/Burnted valves. This can be done with a compression guage remember the reading should NOT be more than 10PSI difference between all cylinders example of a normal reading is cylinder 1 170 psi cylinder 2 168 cylinder 3 172..... abnormal is cylinder 1 170 cylinder 2 85 cylinder 3 172 ...etc. I know this is alot of info but read through and follow these step and you'll be ASE certified by the end of this job. Good luck and thanks for using FIX YA
