rpm drop when revving

[Caliaccord02]

I seafoamed my car last week and when I started to rev it, the rpms started to drop so much, the car almost stalled. Just changed the oil and decided to rev it again and the same happened. What could the problem be?

No check engine light?

It has run fine since seafoaming?

I wonder if it could be the IAC. When this is bad, when Idling, the rpm's will drop and bring the car close to stalling. I had this problem a little while ago. Not sure if this similar to your case, since you say rpm's drop when you rev?
Also had something miscommunicating in the a/c.

No check engine light, and it has been running like normal since seafoaming.
The car does idle under the norm but that happens only once in a while but it is nowhere near as low as when revving.

So you're saying that when returning to idle from a rev, it bogs down a bit?

Does the low oil pressure light flick on when the rpms are low?

 

[Caliaccord02]

Yes, exactly james.
And no Varnell, no light flickers.

Definitely check into cleaning the IACV.

 

[Caliaccord02]

Ill definitely look into cleaning it today or tomorrow and update if it works. Thanks for your help guys.
