LQ1 High Idle

[Padgett]

Magic: got the recorder to work.

 

All at idle: TPS 0% and IAC 0 OAT 93 but car in sun. Foot off gas.

 

Started at 101F coolant and went to 2300 then came down to 1200

0:25 coolant was 115F and 1400 rpm

1:40 125F 1500 rpm

2:20 went closed loop, 1750 rpm code 35 came on. 140F, desired idle 900 rpm.

2:40 1300 rpm and SES went out. 145F

3:00 153F idle 1275 rpm dropping slowly

5:00 175F idle at 950 rpm

MAP did not change much 5-6 psi whole time

 

Idle just high now, not insistent like before: doesn't try to pull away in 3rd at 20 mph like it did.

 

Does that sound like an intake manifold vacuum leak ?
