Question

1999 Pontiac Montana

My montana will be running fine, and then all of sudden it will start to spit and sputter, I have to give it plenty of gas, then it will strighten out and run ok for a while. Is this as simple as replacing the fuel filter?

Hello and welcome.
Is the check engine light, or has it been on?

The check engine light was on, and I had to get a coolant hose replaced a couple of weeks ago, they turned off the check engine light, it has never come back on.

Like I said, it will be running fine, and then start sputtering like it is cutting out....then start running fine again

Answer

OK.
A fuel filter would be a good idea.
Also suggest getting fuel pressure checked. May have a fuel pump
starting to fail.
If you have a sensor problem, you should have a check engine light come on.
