Code po305 is # 5 cylinder misfire. Check the spark plug wire and spark plug. use an inline spark tester to check the wire from coil to spark plug. If you have spark,then remove plug to see if it is fouled out. the best time to check for brake or cracked spark plug wiring is at night with engine running and doing a walk around to see if the insulation on wireing is broken or cracked. you will see the wires sparking at night. then replace the wires that are causing the problem.

2002 Buick Century Limited 3.1L rough idle and P305 code shows up


You have an interference motor. If you had to replace the heads due to the valves possibly touching the motor, you have to consider rechecking the compression after you replaced the heads. I had the same motor that had an intake leak. I found frozen rings on the number 1 piston as well as a bent pushrod. Ultimately, the camshaft had broken due to coolant getting to the bearings. If the spark is good, the fuel is good, then the only other problem you'd have would be compression.

My jeep keeps stalling on me and the check engine light never comes on, people tell me it may be the fuel pump. i have been told it cant be hooked to compuetr because of the check engine light not com


A stalling problem doesn't have to turn on the check engine light . Try some basic thing's like cleaning the throttle plate (body) air passages for the IAC - idle air control valve . There are videos on youtube , also check for a vacuum leak !

Have a p301, p305 codes (misfires) and p401, Engine runs really rough. 120000 and never changed spark plugs. Could a simple tune up fix this. Also replaced the egr back pressure sensor. What else could...


It is most likely an ignition system problem so starting by replacing the spark plugs and wires ia advisable.

If the problem persists then have the ignition module, and coil packs tested.

91 integra ok driving at mid rpm range no hills or coasting check engine light comes on car runs rough and dies. restarts and runs ok but dies 5-10 minutes later


Car runs rough and dies.The issue indicates fuel pressure problem.But as you mentioned check engine light comes ON.The check engine light comes ON when the cars computer (the ECU) notices any kind of electrical problem in car. Once the problem gets confirmed the engine light will remain permanently ON till the problem gets solved. In this case I suggest you to get your car scanned at autozone service center. It's absolutely free. In case in car scanning, if any error code is retrieved then you can check which part is faulty as per the error code. At autozone they also deal in parts.So if any part checked out faulty then you can get that part replaced as per the code.-------------thanks.Helpmech.

I have a 2000 Honda accord with the 3.0 V-6. The engine light has been on so long that it burned out. Now it shows emission code and is dieing sometimes when I stop. I cleaned out the carboned up front...


Have the ODB II codes (computer error codes) pulled and reset. Some auto parts stores will do it for free. Make sure you write them down. You could need new spark plugs and/or wires.
