Default Attempt to fix 4

Well, I follow the instructions to the letter...





I turned CCW first and the RPM did not change at all, then I started the whole procedure again, returned to original position and check RPMs and nothing change, finally I turned it 1/4 but on the CW direction this time and nothing




I'm gonna get ahead here, but I don't have the DLC for Throttle Body Test, another alternative??

My guess after rreading everything on the tag woud be to check the EGR valve but that normally would throw a code, double chek to make sure you didnt switch any vacume lines. Ive had the same problem before and it was a combinaion of IAC and the gaskets were bad. So if u havent already, i would get new gaskets for your throttle body and so forth. My problem in my accord was the IACV was hella dirty and the EGR valve wasnt working right and after i replaced everything it still was having idleing problems which then i did a figured out that my intake manifold was leaking where it bolts up to the block. Like texas said spray around with some brake cleaner to check for leaks and check every possible area and or get a vacume guage buy yourself a repair manual and perform the series of vaucme tests and compression tests just to make sure. Also get a volt meter after you have haynes repair book and double check the ohms on and voltage on your IAC and all other air and emission components. The bokk should have everything in it to guide you and narrow it down. Good luck

Sorry didn't posted the result sooner but I have been traveling the past 3 weeks, right before I left the city on march 30 I check the car again before deciding to take it to a mechanic, I notice the throttle spring wasn't pulled all the way back, so I pushed back manually while the car was on, and "vuala" it got fixed right away, at this point I clean that area (once again) and got the throttle cable loose a bit, it seems dumb after everything I did, I seriously doubt that was the problem, I think that came after, when I was trying to fix it, so I can't say what was it that actually fix the problem.
Bottom line I did not do anything not posted here so, one of those activities fixed the problem.

Thank you all for your support and I hope this helps someone.
