Question about 7AFE idle. Options

[rapid36]

So First off I did some research and I have the exact same problem as this thread http://www.6gc.net/forums/index.php?showto...p;hl=idle+drops Minus the starting issue, my car starts up very quickly each and every time. However I am trying to check my idle, I got the car to operating temp and I did not have the A/C running nor was the radiator fans running, and my idle was at 1,100 rpm. So I did some research on YouTube and I ended up loosening the distributor and twisting it to adjust the timing (I marked its original location just in case I need to go back to the setting I was previous running on) till I got to about 800 rpm (book calls for 700rpm with 5-15 degrees of timing). I tried getting it to 700 but I got it as close as I could and like I said I think its currently running at 800 rpm. Now I hooked up my timing light and the timing isnt consistent so I cant get an accurate reading, I think its cause my idle bounces by like 50-100 rpm constantly fluctuating. Now this car was recently resurrected from a 5 year stand. the motor came from a junkyard online and they said it was tested (not sure how legit that is), The car got a huge over haul, new rear main seal, new torque converter, net spark plugs, new fuel filter, new radiator, new vacuum hoses, new radiator hoses, new spark plug wires, new front and rear 02 sensor, ebay headers and down pipe, magnaflow high flow cat, all motor mounts have been replaced with some junk yard ones that appear to be good, 2 of the mounts were bought brand new.

So I guess my question is the idle suppose to be jumpy by like 5-10 degrees and consistently fluctuating? Is this normal?

Why, it's OBDI. EGR was used on OBDII cars for the longest time until here recently, so then it's really annoying.

The difference in emissions crap between my brother's '95 and '98 Maxima was insane. Same generation and motor, but the '98 had all kinds of EGR garbage that never could be fixed right without spending a fortune just to turn a bulb off.

JK :-), but yeah EGR was a pain for me to fix I had a code for hte longest time but I finally got it all tooken care of and now it works properly. Heres a off topic thing, my car is only getting 22MPG based on how much gas I used vs how many miles I have driven ( I dont know if this is an accurate test) but thats really horrible for having the EGR working properly lol. I have no idea why it would get such crappy mileage, I was getting in the 30's (eg 30-32, however dont quote me on this as it was a long time ago) before i did a retarded thing and let it sit for 5 years. Whats everyone else averaging for the ST models? I am thinking its running too rich but I have no smoke out the tail pipe whatsoever. Im hoping once I figure out this performance thing that I will get much better MPG.
