I haven't seen this with PF's, but Civics have a bad problem with a bolt on the throttle cable catching on a protruding part from the engine. Try following the cable back. If there is a cable tensioner (haven't looked but I'm assuming...), it could be hitting somewhere.

I've gotten that one too. Pulled over for a headlight out. I have that glitch where there is a half-way between off and on where only 1 light comes on. It got stuck and I did not notice and he pulled me over. Guy wanted to search my truck! Told him no (no reason for him not to except privacy), turned on the light and he went ahead and wrote me up after looking through all the windows. Like was previously said, nothing like a bored cop...

Mine lasted 10 years (87-97) and just over 100k miles, maybe 105k. I'm a pretty careful driver and try not to ride the clutch. That was with minor off-road travel, mostly forestry access roads, etc.

For wrecking yards there is also Sunrise Nissan. Based in CA, they have plenty of Pathys to choose from in decent condition. They helped me out a few times as well as my dad ('77 280Z).

I have had the same (or at least a similar) problem. If there is a little positive pressure on the exhaust, you get a sort of vapor lock and the engine will stall out. You will not be able to restart until the pressures equalize again. This pressure differential usually occurs when you accelerate hard and then let off the gas quickly. The exhaust backs up into the engine and kills it. Check out your catalytic converter and/or muffler. There may be some kind of blockage or something.

I live in Tennessee and don't have emissions testing or anything. Although I do love anything that hinders the performance of my Pathy, I may just leave the AIV out completely. I just have all the tubes capped off now, though I have a new (to me) AIV sitting right here waiting to go in (maybe). I am, however, still wondering why my entire exhaust system rusted out. My mechanic said he had never seen a complete system rust from the inside out like that.

Does the AIV hurt performance through emissions? When the engine is running, I definitely have exhaust gas going to the valve. That is, I am sure, where the hole in my engine bay came from. Did you just stop up the tubes running to and from the AIV? That is what I have done for now.

I was wondering if anybody knows why that AIV box is so important and so hard to find replacements for? I have an '87 XE-V6 and a couple of years ago, I noticed a little rust on that round box under the air intake (which I finally found a 2 paragraph section in the Chilton manual is an AIV Valve). Within 3 months, it was completely gone as was the metal underneath. There was suddenly a large hole from the engine compartment into the driver's side wheel well where I could see the tire. The engine started getting really sluggish and began stalling. I took a good look at everything and realized that my ENTIRE exhaust system was destroyed. I have been replacing parts as I can (have a different daily driver) and have seriously had to purchase every part from headers to the tail pipe. I do not know if it was the catalytic converter or the AIV that went first, but apparently one affects the other in a chicken or the egg situation. I have finally tracked down that little AIV thing at a Nissan dismantling yard in California, but it wasn't easy. There is absolutely NO MENTION of this part anywhere on the internet, nor can you find a replacement for it. I had a hard time finding anybody who even knew what the heck I was talking about. My dad has a friend who rebuilds and races and he told me that this part is a feedback loop, and that not having it will make the exhaust system die a quick and painful death (again). Does anybody know what exactly might have failed in this situation so I can avoid it in the future? Or exactly what the AIV is and why it can kill your Pathy? Thanks!
