Got 2004 dodge stratus misfiring code says p2305 already changed coil and spark plugs and wires still misfiring


Who is doing the parts replacing?

Have you looked at Scan Tool Data & road tested?

Have you actually done any testing, to find a problem
& used the codes to component test

Till you answer that, I will say you need a repair shop

Lots of things cause misfires

Changing spark plugs & a coil or two ,based on a code,
is not doing the required testing to find a problem or the
need for parts just yet

97 chevy tahoe running rough update....


code P0303 is a misfire code for cylinder # 3, Possible spark plug, wire/coil or injector problem. P0141, bank1 sensor2, is the upstream oxygen sensor, this code may have been set by the misfire of Cyl #3, the lean condition is being cause by the misfire. Fix the misfire and clear the codes and P0141 should not return. If the vehicle is equipped with Coil over plug system try swapping the coil with any one of the others, test drive and if the misfire code changes to another P0300 code ( P0301, P0302, P0304 etc...) the coil has failed and will need to be replaced.

I have a mazda mpv 2000 minivan.problem code p0301 misfire detected cylinder#1


I'd check #1 spark plug.
Usually a misfire code "fix" is a spark plug, spark plug wire, or a coil pack / distributor.
Keeping it simple...I'd go with the spark plug first and then look at the condition of the wires.

Hope this helps...

I changed the belts on my 97 intrepid 3/3 ltr a couple weeks ago and it stated running rough and misfiring. Changed the plugs, wires and coil pack and it is now misfiring and stalling?


changing belts will not cause this problem.when changing the plugs did you check the plug gap or just assume the plugs were gapped properly.this could be one problem.did you change the wires one at a time or did you pull off multiple wires and change them,this could be another problem(wires not in proper location).you could have an intake gasket that is bad causing a vacume leak,which can cause miss fire.it could be a fuel injector problem(either electrical or fuel).is the check engine light on,this is a starting place have the code pulled.these i would check out.

Engine light keeps comeing on mecanic change o2 senser worked for half hour came back on cods keep saying its miss fireing have had this problem for a month know


Start Small work to Big = Saved Money!
The Code(s) should be telling the specific cylinder(s) that are misfiring. Do you know waht the code is?
Target those cylinders 1st before testing the unaffected cylinders.
The following should isolate the problem(s).
1. Spark plugs - take out-reconnect back to wires and test spark plugs for getting sparks. If none: Don't replace them yet. GO TO 2. If the spark plugs are worn, dirty them replace them.
2. Remove spark plugs form end of ignition wires and test for spark from the wire. If none: Don't replace them yet. GO TO 3.
3. Remove the wires from the coil connection and test the coil for spark for each cylinder. If none: Don't replace it yet.
4. Test each spark plug and wires this way.
5. Coil Packs normally provide fire for 2-cylinders at the same time. The two are paired across from one another.
6. Test the coil for fire, amount of fire and if there is both cyclinders firing.
Misfire and the O2 Sensor got replaced??
Good Luck and get back with me if you need additional help or if this solved the problem.
