Have read most of posts my trouble started around middle of November 22 with slight mis cylinder number 2 changed coil pack problem went away two weeks later had all timing gears and chains redone at 85,000 figured it was time because had some tensioner issues been waiting on parts from rock auto for 4 weeks o2 sensors Maf sensor connector to Maf had short and was stalling out car it’s 1-10-23 now have all those parts mentioned on except for 1 o2 sensor (they sent me wrong one) but still get that slight mis like it needs coil pack which I did buy new ones from rock auto (Delfi)brand still a miss don’t know where to go from here car runs hood on howdy but u come to a stop has that mis just can’t figure it out sorry for long thread first time any help would greatly b appreciated

 

First off, punctuation and proof-reading are good things.

That being said, what, if any, DTCs are you seeing?

 

Remove the spark plug from #2. Does it smell like gasoline.

bring your nose close to the tailpipe.

do you smell raw gasoline?

Fuel injectors tend to fail at this age.
they cause problems like this.

people fix everything except for the injector.
Only to eventually replace the injector as a final and successful repair.

 

I find it really difficult to follow your rambling and what actual work has been done. Do you now have six new coilpacks installed? Let's start there.

 

Ok sorry about my rambling it’s a 98 max 3.0 first week of December 22 felt a misfire scanned it turned out #2 cylinder coil shorted out I replaced it problem fixed. So it has 85,000 on I figured they all would fail soon so I bought the other 5 on rock auto and installed with new plugs during this time timing chain I could here it at start up so I had that installed also with cam gears and chains the whole kit when I picked up car was not throwing no codes but had slight misfire not while moving but at stop that’s where I’m at now and no I didn’t change fuel injectors as always any help would b appreciated I’m taking it back to see what mechanic comes up with also thank you

 

In my opinion replacing the timing chain was totally unnecessary. None of us have done this, even in engines of well over 300,000 miles and much more.
They are not known to fail. Some of us replace the tensioner. Occasionally the chain guides fail.
But not in super low miles cars such as yours.

Common causes of misfire could be

1. A leaky valve cover leaking oil into a plug well
2. A leaking fuel injector
3...A misfiring coil.

Pretty much in that order.

The car works best with NGK plugs. Others can misfire.

Which brand of coil did you install. Some don't work as well as others.

Have you checked the spark plug for smell and wetness like I asked you to? Does the exhaust smell like gas?
it's the engine difficult to start after it's been off for several hours ? If so, does it emit a stinking gray cloud when it finally does start. All these things indicate fuel injector issues. Many of us have failing injectors.
Many fail just due to age. A failing injector does not cause a check engine light most of the time.

 

Sorry for not posting since my last rambling but here I go did what was suggested it helped out diagnose problem I put shorting out pig tail on maf sensor changed all new delphi coils(which I can’t return)back to factory ones been running great since last post 1-9-23 I think thx for all ur help and I agree installation of chains was not needed tensioners should have gone that way but already their well mechanic told me same thing thank you all I’ll b reading to try to help if I can

 

Welcome to the forum.

We help our members identify the actual problem.
or at least eliminate other possibilities.

Firing the Parts Cannon at a problem gets expensive.

Sometimes the Parts Cannon is fired while chasing wild geese.

Seems like the shorting pigtail by the MAF was the actual problem.

 

Fuel pressure?
