First let me say I do not have testing in my state. I do however plan on running a cat and full exhaust.
All of the following applies to a Sidekick 1.6 8V with TBI.
Is it possible to delete/remove the rats nest (vaccum lines and associated parts), egr, cold idle etc? I want to eliminate all the extras I can. I beleive I would need an EGR block off plate (mabye some others). This is on a 1.6 8V Sidekick. The motor has 150K+ miles on it and I want to eliminate as many possilbe bits and pieces that can and might already not be working right. Is there a write up somewhere with directions on what vaccum sources to cap and which remain? I'm guessing with most of the items removed only one or two vaccum lines would remain. Is this possible on TBI (I only have experience with EFI cars in the past).
I have done such a thing on another vechile and was happy with the results. As it is now the idle is high when the engine is cold or warm (cold idle might be stuck). It also sometimes backfires and chugs/shakes violently. I am going to do plugs, wires, cap and rotor button. Seamfoamed it yesterday and the lifter nosie has died down. I figure all of these little bits and pieces are fairly dirty or worn (and with cost in mind not feasible to replace; I got the truck free).
TIA

I don't think you can do what you want to do with the TBI system. All the sensors (vacuum and electrical) work together to make the engine run as efficiently as possible--with the least amount of emission problems. Start unplugging stuff and it'll just get worse.
Your best plan of action is to replace all the vaccuum hoses, change out the PCV valve and replace the EGR valve. Replacing the EGR valve may also involve cleaning the passage that crosses the rear of the head from the #4 cylinder exhaust port on the exhaust manifold. That task is a bit labor-intensive, but if it's your labor, no problem!
You might be able to get a rebuilt EGR valve from sarge at morepowr|removethispart|@theramp.net.
You mentioned that sometimes it chugs and backfires... Take a look at the crank pulley - does it wiggle any? If so, you may have a damaged keyway/woodruff key on the end of the crankshaft. The symtoms of this problem is increasingly erratic timing.
It is also possible that the timing was not set correctly. There is a 4-connector socket with a cap near the battery. Two of the conectors must be jumpered together in order to bypass the ECM when setting the timing. The ECM constantly monitors timing and adjusts accodingly. When you are changing the timing, the ECM interferes with the process! Most aftermarket service manuals describe the tuneup process including how to use that connector to disable the ECM. You can find the Chilton and Haynes manuals at most public libraries. The Haynes manual may be listed as a Samurai service manual but also has Sidekick/Tracker sections.
Hope this helps!

Thanks. I am going to tune it up and check the timing. I will also check the crank pulley. I have seen that on Samurais (also a common problem on early Miatas). I ran some Seamfoam through it and hope that got some of the junk out of everything. I have pulled an egr before and cleaned it as well as the block as you mentioned. Guess I just need to get on it.

Good luck and welcom to ZukiWorld!

i was trying to diagnose a problem with my truck and i had the egr disconnected so it would not open. i would not recommend removing it because after i cleaned the egr and got it free it seemed to run a bit better. as ack says all those sensors work together to make the vehicle run right. disconnecting stuff can cause it to run rich or lean and thats just no good as one is hard on your wallet and the other is hard on the engine.

Question
Does the 16V MPFI engine have less emission control items when comparing it with the 8V? I meen when it comes to the censors and things.
Thanks

16V has more sensors than the 8V model, specifially the OBDII engine
