Hey guys...had a rough like after taking car out of storage. She will run smooth at idle, and smooth sometime when stopped while in gear. Sometimes idle in gear and park little rough. Give doe gas and seems to smooth it out sometimes?!?!

I have changed plugs and wires, ran the tank of gas out and filled
Any ideas; o2? Fuel filter?

52,000 miles
Well maintained, just not sure where to go from here...any thoughts? Thanks

Any fault codes?
How long has it been in storage? Maybe it just needs a good open road run. O2 sensor and fuel filter are quick and easy and cheap so worth a shot.

Not throwing any codes, no engine light...was stored Dec until early March. I did run it a few times to temp over winter as we had a pretty mild winter for Michigan. Thanks for reply

Possibly carbon build up in throttle body. Varnish from stale gas; can take a few tanks to clear out.
