Engine not idling at steady rpm
My Nissan is a 1999 SE with manual transmission. No ABS.
The problem is that when it idles, it jumps a little around 600 rpm. It never did this before, and I am getting worried that something major may be going wrong with the engine. What's really dangerous about it is that sometimes while I am driving, the engine will go to such a low rpm that it will actually shut off. Turning it on is not a problem. Either re-engage the clutch or keep it in neutral and re-crank the engine. But if it does shut off, say, in a turn, I loose power steering and get very close to the side of the road. It's unexpected, so I could get into an accident one day.
In my attempt to fix it, I put a fuel injector cleaner into my gas tank once, and I changed the oil and oil filter, and I changed the spark plugs. I don't know what else to do. Any tips would be very helpful. Thanks in advance.
One more thing, when it first started happening, it wasn't low rev's. It was high revs. The rpm would jump from 700 to say 3000 and then 2000 and then 4000. Basically, it would go all over the place. But later, that stopped and now this happens. It doesn't make any sense.

1) clean IACV and pieces
2) clean MAF
3) double check hoses for Vaccum leaks
** only use MAF cleaner on the maf and throttle body cleaner for your IACV and all of it's nooks and crannies. Using the wrong type of cleaners can cause more problems.
In retro-spect... the ign. coils are probably not the issue neither is the tps. I thought that you had done a proper cleaning already. My B!
