Air induction system

[872door]

Has anyone had any problems with their air induction system? This system is designed to reduce hydrocarbons in the exhaust by drawing fresh air directly into the exhaust manifold as per the Haynes manual. On my 87 it has had a total melt down. The filter and surrounding area look as if acid has been poured over it. I just bought this vehicle and when I first saw it I thought I was looking at a battery melt down. It has eaten a hole in the fender well the size of a grapefruit. The Vehicle runs smooth and has no major problems. I was just wondering if I could do away this system? Any ideas or suggestions on what needs to be done? :help:

I have never even heard of such a problem.

You're taking about the charcoal canister, right? The one on my 87 did the same thing, the bottom rotted out and made a big hole in the wheel well right where the coil mounts. I just pulled all the induction stuff off and capped the line fron the manifold and cat, then fiberglassed the hole. It passed emissions in VA when the canister was rotted out, therefore I don't think pulling the system out made a difference as far as smog goes so don't feel guilty if you do it.

Actually the canister looks brand new. So this could have been the problem originally? Maybe it was replaced by the previous owner? The filter on the system, the mounting hardware and fender where the coil are mounted are destroyed by what looks to be rust. Does that sound like what you had go wrong? Ireally dont know where the coil goes originally because I found it just laying in the wiring harness behind the drivers side headlight. Did you remove canister and all?

 

 

P.S. We dont have to worry about emmisions in Al....... Yet

 

Thanks

It looks like mine had the same issue, and I am planning to remove it on mine. My coil was just laying there like yours, looks like the area it had been mounted to was "repaired" (someone threw a piece of sheetmetal over the hole).

Yeah, the canister on mine was completely wasted and left a melon sized hole in the fender well. I removed everything associated with the air induction system and plugged the pipe from the manifold (header on mine) and the cat. Then I remounted the coil to a bracket on the fender well just behind the headlight after I repaired the hole with fiberglass and flat back paint. I still need to get in there and figure out how to remove the rest of the pipe from the header. I can't get a wrench in there to bust the thing loose so it's just capped off for now.

JJ, What did you do about the vac switches. Did you remove them and plug the vac lines.

[jj big shoe]

I honestly don't recall, but when I asked for the same advice you're looking for on the board, the response was to plug all the lines and rip the system out. BTW, I didn't notice a performance difference at all probably because the can was so rotted out it wasn't doing anything at all. It ran just the same.

Th eair injection system and the charcoal canister are 2 diff things I thought. The charcoal absorbs fuel vapors, whereas the air injection systen was an early and expensive attempt at pollution control. My entire air injection system looked like a ball of rust, I ended up getting a couple of pieces from junkyards but most of it came from Nismo (expensive). It had a filter canister, reed valves, filters, diaphragms.. what a mess. I guess from the sounds of things, you can cap them off without major issues?
