Occasionally sputters around 3k Rpms like it's struggling to accelerate. After a few seconds stops and drives like normal. Only happens like once a day. Suggestions?
 
My guess is that ONE of the spark plug wire connectors is loose. Like were the spark plug wire attaches to the spark plug. Try taking each spark plug wire off and on again to feel if any of them have less resistance to coming off the plug than the other ones do... If one of them comes off easy compared to the other ones then that could be the problem right there..Loose connection.. Had it happen to me before with cheap spark plug wires..

After that I would replace the spark plugs with (NGK), with the proper gap.
 
I had a similar problem and my throttle position sensor and fuel pressure solenoid had a poor electrical connection. I used some fine sandpaper to get rid of the corrosion and the problem was gone.
 
Thanks guys I didn't suspect that but it's problably right on. I have messed with them a bunch lately between testing. So that's probably it. I'll test the connections and get new plugs and wires
 
Had a similar issue a few weeks ago. Replaced plugs and wires and cleaned my air filter, and the issue was gone. Wouldn't hurt to poke around for intake and vac leaks.
