Icon9 Intake manifold question/ cleaning

I live in CALI and smog is strict. Gay !!!
2 weeks ago I went to get my car smogged and my NO2(NOx whatever) level was high. I already cleaned out my egr as suggested by my stepdad.
I called local shop to get a quote on cleaning my intake manifold from 2 different shops.
KBR tuning- $200. I know the workers and owner.
HybridWorks- $495.15. I know the owner but he's strict on his work and pricing.
I don't have deep pockets and I need my car to pass smog and run normal.
It's a 95 prelude SI Vtec. And it's a DD fully stock with absolutely no modification what so ever.

What do you guys suggest I do ? I already tried seafoam and it didn't work.

I also should mention that I bought the car from a guy who had it sitting for almost 4 years but occasionally started the car but didn't drive it.

Any advice will help. Thanks in advance guys/gals.

Re: Intake manifold question/ cleaning

Where all did you use the seafoam? I live in FL so I have no idea how that works over there or else I might be able to help out. I'm willing to bet that that 95 has a bunch of miles so it might have a bunch of carbon build in the head that might have a large effect. Good luck and hopefully someone on here went through the same problem and can give you advice. You might be able to seach for it in here or you can wait and someone will assist you.

Re: Intake manifold question/ cleaning

Did you clean out the EGR and it's ports? May want to replace the cat, get new plugs and stuff basically just give it a nice little tune up, do not pay anywhere near that to have your IM cleaned, I took mine off myself and the guy charged me $30 to sandblast it and some other little parts also.

yeah i cleaned the EGR valve but not the ports. i havent done anything like this so im kinda if-y on it and the ports have jb weld on it and i have no idea how to get them off. i am still thinking about taking the intake manifold off and just cleaning the entire thing out but i dont know how and i dont want to mess up anything

Re: Intake manifold question/ cleaning

cleaning those ports makes a huge difference, you should def look into it. it isnt that hard. taking off the manifold would make it alot easier and you could get everything else cleaned up. it isnt hard to take it off, just put everything back the way you took it off, dumb advice but it works lol
