I currently have a check engine light on
and my RPMs while idling is way below normal. So, here is the story:
About a week ago the check engine light came on. It was way overdue for a tune-up so I took it in and had that done thinking that after it was done it would turn the light off. It didn't. Also, I didn't notice it before the tune-up, the RPMs while idling would be around 500
(normally would be around 1000) and would also drop down to 300 and then back up to 500. Then two days ago, I went to start it and it turned over and then died. I had it taken into a shop and they looked at it and said it was an IAC sensor wire that came loose. They plugged it back in, reset the system, and the light went off. Today as I was coming home from work, the check engine light came back on and the RPMs have dropped a little. Not as drastic as before but down to 700-800. Any ideas on what it could be? Thanks.
