A few months back, I put my car into park from reverse while it was moving. The idle then bounced on me. I fixed it doing the idle relearn. Here's my original post.

Engine surging after quickly shifting from Reverse to...

Hello! I was reversing out of my garage in Reverse gear when I engaged the Park before coming to a complete stop. Stupid yes. I know! The engine made a bad noise briefly. Now I have a problem where the engine is surging in any gear I am in. I believe this may be related to a sensor. I do not...

Well folks it's back, and this time the Idle relearn does not fix it. Problem started after seeing the mechanic to change a LHS motor mount and he had to disconnect the battery. I decided to try to fix it myself, here's what I've done.

1. I removed the Throttle body.
2. Cleaned it, was not dirty.
3. Removed IACV, cleaned it, but couldn't twist the thing due to the Torx 5 point security screws bolted on the side.
4. Removed TPS, inspected it, didn't open it up. Seemed OK. I had to tension the internal spring to put it back on, twisting it a little, is this normal? Also a small part of the green cardboard gasket tore off, so I just held it in place while bolting it. Unsure where to bolt it, had about 10mm of rotation.

Some coolant did leak while removing the throttle body, I accidentally removed a large rubber hose from the engine block. As u can tell I'm not super experienced with this!

Can anyone help?

Follow all the hoses on the air intake side of the engine. Look for splits, breaks, holes etc.

Moving to Gen 2 Section for better response.

Remove IACV, but actually remove the motor and twist the valve around. You will need to remove the throttle body (you can keep the throttle cable on there though). The iacv is on the underside of the throttle.

You will need a 5 point Torx TR bit TR20 i think to remove the motor on the iacv.

Put some clean fluid like solvent, soak it, toothbrush. Get it spinning as nice as possible,then drop a bit of oil in the valve and re-install. I used 3 in 1.

My idle has never been better, its great, much more responsive accelerator pedal.

You wouldn’t believe it unless you saw it...I removed the IAC motor to have a look at the housing and found a stinkbug jammed in the rotor...

Unbelievable...
