Replaced IAC, High idle. Please help.

Cleaned throttle body, hesitated and rough idle at start, but running smooth now. 1300rpm.

 

Check engine light is on now, wasn’t before.

I just replaced the IAC. Weird.
Should I just drive it around for 2 to 3 days?

Thanks!

 

Did you happen to clean the MAF while you had the intake apart?

 

no sir I did not. I just unplugged the connection.

 

And I plugged and unplugged it again to double check.

 

Clean the MAF (with MAF safe cleaner), pop off the electrical harness and clean that with electric contact cleaner. Pull the EFI fuse while you do that to reset the ECU, and then go drive it around.

 

The first thing I'd try is some MAF cleaner, and check to make sure you don't have any loose or broken wires on the connector.

 

Id try disconnecting battery for a few minutes then connect back up

 

not too many things to investigate.......

 

tht IAT sensor, doesnt it just plug into airbox....into a rubber grommet?

 

Yes.

 

no that is the MAF pigtail^^^
there is a small little plastic pointy thing/sensor
gimme a min

 

Here:

 

I did not have that. I just went and checked.

 

Before I forget, thanks guys. I appreciate all of your responses. I’m gonna do everything that was written here.

thanks again for replying.

 

Just looking at those codes- I would also suspect a vacuum leak. I assume you would have had to remove the TB and any associated vacuum lines. Judging by the corrosion in your picture, if you haven't replaced before any vacuum lines, they are probably due for replacement. I would also double check that the IAC and specifically the gasket were installed correctly and air isn't getting through there.

I will replace those 5 rubber hoses connecting to Throttle body that I took off to clean it.
thank you.

 

@Andy01DblCabTacoma

since you mentioned the IAC gasket

when I first started it, some smoke was coming out of thar area, about as much as a big drag on a cigarette, then it went away. Could that be throttlebody cleaner, and the coolant that I let drip from the line?
