I don't think its that because my idle has started surging. That leads me to believe it's a bad 02 sensor (or both upstream sensors), or a bad TPS sensor.
I'm leaning more towards the 02 sensors because I did a seafoam treatment through the brake booster vacuum hose last November.
My engine started slightly missing two or three minutes after startup shortly after the seafoam treatment. 1500 miles later, the idle surges up about 300 rpm and back down to normal every two seconds at normal operating temperature.
I think it might have coated my 02's with some build-up because I only ran it about 4 or 5 miles to burn all stuff out. Then I parked it not letting the 02's burn off all the gunk going through them.
My engine didn't have any problems with idling until after I did the seafoam, just a pinging problem that was fixed.
There still is no SES light illuminating?
Quintin? ProjectSHO? What do you guys think?
