Hit and miss or change and see proceedures can get verry costly and as you observe not fix the problem. If it's not broke keep fixing it till it is. Sorry. Codes tell you where to go to ffind the problem and fix it only. As you have changed a number of things it would be good to reset codes by disconnect battery for ten min and have a coffee. reconnect and test drive to see if you still have problem and havn't accidently fixed it already. if not then start with codes and go from there

Why did you change anything at all? Makes no sense,
as you found out

Should be studying OBD2 Systems on the internet

Where are the codes you got--- so we can weigh in?

Ignition coils


You didn't put a problem in there,
you never got the bad coil or coils out.

If you went by some coil codes, that's why

You may have to walk a new coil, replacing the
old one & test drive 20 miles & spend a few days
doing so.

The Spark Plugs can't be over 3 years old or
50,000 miles & front O2 Sensors over 100,000 miles

When i start my 2001 kia optima my car putters. i changed my bad o2 sensors. but not sure what the problem is. and when i drive sometimes it jerks. what could the problem be


The spark and fuel system needs to be inspected.--------- The spark plugs are getting fouled or very loose, can cause sputtering problem.Inspect the spark plugs and coil packs.The spark plugs gets power from coil pack.If the spark plugs are very old and dirty, then it needs to be replaced.--------------- The **** problem also relates to faulty worn out spark plugs or clogged fuel filter or low fuel pressure or problem with ignition coil pack.----------- When coil pack stops giving power to spark plug the car will **** while driving.---------- So very first thing you get tested is spark plugs and ignition coil packs.If they are tested good, but looks very dirty/ worn out, that can also be the reason.----------- But if spark plugs and ignition coil tested ok and cleaned properly, but still same problem, then get fuel pressure tested.If fuel pressure is low, the fuel pump and fuel filter are the cause of problem.----------- ------------------ Also one more thing, " IS there check engine light coming ON dash" ? If yes, then get the car scanned at autozone service center.Its absolutely free to get car scanned at autozone.They do it for no charge.------- In scanning you will get error codes, as per error codes, it will point towards faulty part, causing this sputtering and jerking problem.----------------- But if there is no check engine light ion dash, then get the above mentioned possibilities checked.That will help.Thanks.Helpmech.

Car engine start shaking


you may want to try haveing the fuel injectors cleaned they can also cause miss fires also try flushing the fuel rail to flush the rail just hook up fuel gauge and turn the key on and remove the gauge from the hose and let it run into a container also look at fuel and see if the quality is good should be strong smelling one cup should smell up a small garage if it doesnt try a different brand of gas

'02 accent GS misfiring & O2 sensor slow response


HI first off the O2 slow resp code is an exhaust leak and not the O2 sensors itself. Slow resp codes is due to to the O2 reading 2 much oxygen or to little exhaust caused by a leak. Now on to the more important. first thing you should do is go buy a can of starter fluid or 2+2 gum cutter and spray it near the injector number one if the intake gasket is or the injector is leaking the car will sputter than run ok for about a second and then start miss fireing again. Dont buy a coil yet. Try this. get a plastic spray bottle and fill it with alittle luquid soap and the rest water. spray the coil pack and look and listen if you hear a clicking noise or a a blue sparking arking off of the coil, also do tis with a your spark plug wires. One last thing if your spark plugs are not ngk thay are wrong and that also maybe part of your problem.
