I replaced Engine cover gasket 4-5 months ago, Replaced Danco brand spark plugs as well as Spark plug wires at the same time when this car had same misfiring problem at that time. Problem was solved but 2 weeks ago this misfiring or jerking problem started again. What did I do wrong? My has 124000 miles.One driver.Engine check light scanner showing "Random misfiring code".3 weeks ago, I used Sam's club cheap gas. That causing Fuel inj.problem somewhere? I just added Fuel inj. Cleaner today in gas tank.Still I don't see any change.Please answer me. Thank you.
I don't see any engine oil level going down on dipstick. If it can not be cleaned, do I have to replace it? I would appreciate your help in this matter.
