No you don't have to drain the oil, however if there is oil down where plugs are then that may be the reason for the misfire the oil blocking the spark or may actually be the cause of the coil going bad. You have another problem that needs to be taken care of if not you will have the same problem again soon. You need to change the oil seals in valve cover gasket and valve gasket to stop oil from getting on plugs.Good Luck and thanks for using FIX YA

My number 6 sparkplug is misfiring on my 2010


Have a compression test done on number 6 cylinder to see if compression ring or valve damage is causing misfire. The ECM can also be the cause as it controls the firing of the coils.

What does po302 mean on a 1999 plymouth neon


Check Cylinder pressure. PO302 is a cylinder misfire code. you have 4 cylinders in your car. You need to find out whats causing the misfire, could be something simple as changing sparkplugs... could be something a bit more advanced like changing rocker/lifter arm.. It's not something that you would want to drive around with for a while, it could mess more up than it would cost to fix right now.

Miss fire but no lights on changed the plugs and fuel filter also changed dist cap also checked for a good spark


A lean fuel mixture will not yield poor fuel economy but a misfiring cylinder will.You have already replaced the coils and the plug leads to the cylinders in question so they should not be an issue.Do the codes still indicate a misfire on cyls. 2 & 3? If so have you looked at the plugs? Has the oil leak around the plugs been stopped? Are they oil fouled? Could the pooling oil around the plugs be shorting the spark discharge to ground?or Valve Cover gasket is leaking. That's why you see some motor oil in the sparkplug sleeve (tube). removed the spark plug and My suggestion is to remove the sparkplug in cylinder 2 & 3 or whichever ones that the scanner indicated as "misfiring". Take a look at the sparkplugs and see if there's any oil around it. If you see any traces of oil, that means your gasket is worned out and need to replace.Good Luck in getting your problem fixed. If you need any further help - I'll try to help you the best of my knowledge and skills. You can repost on this

I have a 1999 audi a8 q it is runnen rough had a tune up dun that did not fix it and also had oil changed.had it put on computer and shows the number 4 sparkplug misfiring....now sumtimes it will run...


no heavy oil not going to help misfire. if you have a cylinder misfiring it has to be plug,plug wire,coil ,dist.cap &rotor,vavle,or piston rings ,an sometimes it can be headgasket . what u need to do is a compression check on all cylinders to compare to rest of them & do a leak down test on each cylinder only if the compression test are all the same psi. on all cylinders if u do this you will find the cause of the miss fire .

OIL IN SPARKPLUG TUBE


Sounds like one of two things. One is it has had oil spilled while adding oil and it has ran down into the chamber by gravity. The other is a leaking valve cover gasket.
