Hey question on what my next step should be with my 09 Elantra with the 2.0L. Background:
I had a very slight misfire for about 1200 miles on this oc of m1 ep 5w20, that would only feel noticeable on cold starts shortly or under 1500 Rpms when warm with very light throttle input. I replaced spark plugs (NGK), air filter(fram ultra) and cleaned maf and even changed the transmission fluid… 3 times with no change and just “assumed” this motor was not a smooth motor. I still got over 32 mpg on highway, and never a check engine light. But fast forward 1200 miles and a month later I wanted to change the spark plug wires because that was one component I did not change as I again “assumed” the wires have been changed out with Hyundai oem wires at some point. I was wrong! They must of been the original wires from 2009 with 115k on them because the new premium wires I installed made the engine silky smooth, better throttle response, and no more slight shudder at 1500 rpms and under. It even starts a lot easier now when cold… the throttle response feels great and it pulls alot better lower in the rpm range without need for down shifts! It even redlines faster so the old wires were shot and long over due.
The question is should I change out the oil? It does smell of gas but never raised on the dip stick. Would the gas in the oil evaporate and I’ll be okay or am I doing engine damage and should change out ASAP? This again was not a “hard” misfire with a check engine light but it felt like more so like a incomplete spark or half strength spark misfire if that makes sense. Now that it’s running correctly I noticed it’s again a lot smoother almost Honda smooth haha.
Let me know what you think, thanks in advanced
