rough idle

[Brian Kirton]

My ST seems to have a rough idle when outdoor temp is cooler. I didn't have any problems on the warmer days but now that it's cooling down some I'm starting to notice it again. I took it in last fall b/4 warranty ran out and was told that it was normal b/c it was a SOHC.

I asked on this site and was recommended Sea Foam treatment. Ran the treatment through twice since last fall and still rough idle. Any suggestions or is this normal?

You might try cleaning the Idle Air Controller.

1st go with what paul said... then inspect how clean your Throttle body, spark plugs + wires are... and your air filter...

After doing the above clean your Mass Air Flow Sensor by spraying some CRC MAFS cleaner on the two little wires in the MAFS. Remember Not to touch the MAFS wires as you could break them, and that will be costly.
