I like how the haynes manual doesn't tell you about stuff like hard vacuum lines bolted to the surge tank. I nearly ripped them right off in a fit of fury.



Anyway, what does the BAC do? advantages/disadvantages to removing it? *nevermind, found answer in pinned topic*



Where is that blasted ECU ground that people suggested I need to reground in order to [maybe] fix the 3800 rpm stutter? I'm pretty sure someone had a pic.



How do I know if my car is a California model? There was one part the manual said to remove (except on Cal. model), and it wasn't there. I think it was the cold start assist thing bolted to the passenger side of the surge tank. Any tips?



How do I clean the intake for the secondary ports? It's looking pretty nasty in there. Anything that goes in there ends up playing with the rotors, right? not as important, but how do those areas (6-port intake) get so much dirtier?



I'm proud of myself for not stripping any bolts. yay.

 

Here's a thread with some pics of that engine ground that Mike pointed out: engine ground under intake



For the auxillary ports (I take it your talking about the lower intake manifold, not the actual engine ports, right?), I think they get dirtier due to the oil metering lines spraying oil in... then again, there are two also on the upper intake that make the runners dirty as hell too. To clean them, I started by spraying it good with carb or brake cleaner, then used a flapper bit on my rotary tool which you can use also for mild port/polishing.

 

cool...I know where that is



If I get to cleaning there, is it ok if the stuff falls into the LIM? should I stuff a rag down in there ahead of time?



where can I find a block off plate for the bac? and if I remove it, does that include the electrical thing that plugs into it, and is supported by a metal bracket? also, can I remove that air pipe that runs along the top backside of the TB and dynamic chamber?

 

www.k2rd.com sells nice and cheap block off plates...they come with hardware too

 

I meant with the LIM off the car. I'm not sure about the BAC now, I think I'm going to leave mine on after reading pengaru's post in the TB mod thread.

I'm thinking the same about that other thread.



Is the LIM the same as the "surge tank?" Or is the LIM what the surge tank connects to? (what the manual refers to as the surge tank is that curved, 4-chambered part, right?)

 

lim = lower intake manifold; its the part the actually bolts to the engine

what's the best way to clean out the intake to, and the secondary ports?



and by best I mean most efficient (effective but not too difficult)

 

Baldy, when I mentioned above about the carb cleaner and rotary tool, I was talking about the lower intake manifold off the car. Are you asking about the secondary ports on the block itself?? If you are I have no clue, I haven't touched them.

 

i like to pull it off and clean it with carb cleaner, or the solvent of your choice
