Like the title says my maxima is hesitating to accelerate and j don't know what it could be. There's no misfiring or anything all my coils are cool. The exhaust has no holes or anything. Idk what the damn problem is. Please people help. This issue has my check engine light on and I can't pass inspection!

 

Maf

 

Mass air flow sensor bud, does it pass over 2.5k RPM? need more info what your problem is

 

It will go well over 2.5k but when driving it's like it will hesitate while I'm gassing like its holding back then it will let go and take off. I remember when I got the codes checked one of them was the AITS but my max didn't have one because the previous owner cut it off for whatever reason so I fixed in a used one from the junk yard and that's good now! I'm going to get it checked again tomorrow to see what codes are still there.

 

If the CEL is on then there's a code stored ... what's the code(s)?

 

Is the car up to date on maintenance? Spark plugs, fuel & air filters?

 

Yes just gave the car a nice tune up. Oil change, oil filter, air filter, antifreeze was flushed, spark plugs. I'm going to try and make it to get the code checked again. I wrote it down before but lost the paper

 

I just noticed while driving that the car struggles to go over 2.5k then sometimes it will jump to 3k and make down to 2.5k

 

Sounds like the MAF is on its way out. Try to clean the MAF with MAF cleaner. Check for any vacuum leaks too

 

try maf cleaner. If it does not help, Purchase a used maf at a junkyard and install after cleaning with maf cleaner. Do not replace anything until you see the codes, although this does sound like your maf. You can check the codes yourself. There is a guide in the stickies. READ IT, it is very easy.

 

Ok I used my head and did some reading in the stickies and all that jazz and I just came from getting my light checked.

Now over the weekend when I checked it only should 3 codes but today looking back the scanner he used looked out of date and old.

They used a newer one today.

I now have 5 codes and this is what they are!

P0443
P1441
P0141
P0110
P0306

The last one for sure is cylinder #6 misfiring! So I'm going to jump on that ASAP!
But as for the others were do I start!?

 

If your MAF is on it's way out here's how to check it..
