Hesitation when taking off

Finally fixed the Range sensor and now I'm trying to figure out this other problem.

I have no issues giving gas or acceleration on the highway. Only when I come to a stop and then I have to give it gas to take off it hesitates/sputters.

We're getting no code. It feels like it wants to die when I go to take off. But once I'm past the take off, it's fine...It's stopping and taking off is the issue.

Unplug the MAF sensor and see if it runs better. If it does try cleaning it with MAF cleaner.

We can drive it ok with that unplugged? Obviously it will be a trip around the block to see if it does it, but it will be ok?

That would put it in default fuel mode and wouldn't hurt to run it like that, It fine tunes the mixture and timing for good mileage and power.

Re: Hesitation when taking off

Have not gotten around to do this yet but just received the check engine code P0302...Now it makes sense that something is not right...

How can I check for a faulty Fuel Injector or Catalytic Converter? We will be replacing the spark plugs this weekend and hope that's the cause.

That may help. Check the wires too. Cyl #2 is the code.

How can I check the cat converter or fuel injector to see if they are faulty?

Re: Hesitation when taking off

If the cat was plugged, it would have running issues on the road too. If an injector is bad, you'd have a fairly steady missfire in most cases.

Re: Hesitation when taking off

OK, it's fine once up to speed. So it could be the injector? The getting up to speed is constant. Is there something I can do to test the injector?

Re: Hesitation when taking off

The injestors are rarely a problem. They would have to be checked at a shop to see for sure what's up with them. Deal with the plugs and wires before worrying about them.
