If it is refering to a multiple engine misfire, it has to be something that all cylinders have in common. If the spark plugs have been changed and an inferior brand used(or improper for that vehicle) it could in fact cause this. Double check for oil leaks near the plugs and wires. Oil leaks can cuase arcing and misfires. It can also be attributed to contaminated fuel. Take a fuel sample and see if you have water in the fuel. Let me know.

    hi thank you, tomorrow I will see the spark plugs and replace all of them,some one said that it can be the cramshaft sensor or the camshaft sensor too. giving me the misfire. (I changed the Computer too)



    regarding the oil, last year the oil presure sensor was replaced,it had a driping but it was fixed, the mechanic changed the oil sensor because the radiator broke and the antifrez got into the cables and the oil sensor cables broke a part. the problem with the oil light is something strange in (P) flikers when I drive stop blinking but when I stop at a red light the RPM go low and the light goes On is only when I drive (D) it goes away. aaa the level of oil is correct and no oil on the floor , I did check by puting a board under the car for 1 hour and having the car running.



    aaaa and yes I increse the RPM a bit to see if that make the oil light go away it works for a minute or two but it comes back again. dont know what to do I am a disable person and My car are my legs.

    should I look into buying another car?



    Thanks

    I personally do not have a high opinion of Daewoo but if it's bought and paid for, the repairs might be less of an expense. I do hold a very high regard for Mercedes and Nissan. I would also change the oil filter with a genuine manufacturer oil filter. There is a difference in how they are built and the pressure that can be maintained.

These codes are making me lean towards the ignition coil pack.My stepson's 2001 Sable 3.0 v6 had one cylinder misfiring(5-code P0305),which shares a coil with cylinder 1(code P0301).I diagnosed it by trading wire 1 and 5 at the coil,and the code changed to P0301.You have codes for the two cylinders on the same coil,so this is most likely it.(these codes would also trigger P0300(Multiple Misfires Detected) and P0316(Misfire Detected First 1000 Revs)).

My 2002 envoy has a miss that just started==was driving on the freeway for about 40 miles @70 pulled n a station to get a drink ==started it back up and it started missing like a dead plug or coil i...


2002 Envoy sle 4.2 L straight 6. Random misfire(PO300). After erasing codes for several days, I finally took my car on the highway and ran it at high speed(70+) for about 4 to 5 miles. Check engine light came on as before but this time it gave me(PO305). Random misfire cylinder 5. So I switched coil 5 with coil 2. Went back out on the highway and repeated as before. This time it gave me(PO302). This was telling me I had a bad coil. Replacing one coil pack solved the problem. The professionals told me low fuel pressure would not give me random misfire, but rather a O2 code because the engine is running lean. Thank you------------------------------------ thank you very much.

Surging/loss of power up steep hills in Daewoo Lanos 2001


This sounds like you may correct in saying a misfire. this sounds like a bad coil that looses power under a load. Is check engine light on?
If the light is on or not go to an auto parts store like auto zone.At auto zone they will scan the computer free of charge and give you a print out of any codes. the computer will store code or codes when it detects a problem. A bad coil will make it store a code or should.
see if there are any misfire codes, this code will help pin point the bad coil. if there are codes write me back and give me the code. I think this car has coil over plug ignition system. this just means instead of sparkplug wires the coil sits right on the top of the plug.
Also replace spark plugs if it has been a while since they have been replaced. check air filter too. a matter of fact if you have over 70,000 miles on car tune it up. plugs,furl filter if it has one, air filter and pvc valve and clean throtle body.
Okay, just checked it out, this car if a 1.6 engine then does have a coil but not on spark plug, rather coil with sparkplug wires going to plugs. try replacing spark plug wires and plugs first and if problem remains then replace the coil. let me know the results. good day

Engine light comes on - Code shows P0300 and then


OBD II 300 Random/Multiple Cylinder Misfire Detected

When the misfire monitor detects a misfire, it will trigger the check engine light with the specific cylinder number as the last digit in the P030X code. For instance cylinder 1 misfire is P0301, cylinder 2 is P0302 etc. In this case we have either multiple cylinders misfiring, or the computer simply can't determine the specific cylinder, and as such we are left with the P0300 in computer memory.

Possible Causes:

Fuel injectors, related wiring, sensors and computer issues
Running out of gas, or poor fuel quality
Evaporative emissions system (EVAP) concerns: fuel vapors leaking into engine
Incorrect Fuel Pressure
EGR system concerns: leaking EGR valve or restricted ports
Base engine concerns: low compression, valve train problems and timing issues
Ignition system concerns including, but not limited to:
Faulty spark plugs
Faulty coil or related wiring
Ignition module or related wiring issues
Ignition related sensor faults or wiring issues

STARTS HARD. CODE 300 MULTIPLE MISFIRES. 141K MILES


My first thought without viewing the codes is a camshaft sensor, But I will get back with code description. But thinking further, if your alternator has a bad diode or regulator and you battery goes dead, and you are certain your battery is ok, then it would have to be something like that, and the code is because your loosing power as your battery drains.


(1) have battery checked
(2) Alternator checked!
(3) an easy way to check is disconnect battery and see if it goes down. If it doesn't, then check alternator next.
(4) bad coil packs or crank sensor, vacumn leak, bad hose or disconnecter.
(5) bad wires.

Hope one of these helps. It is hard to diagnose this problem online.
