weird power loss
Max was driving great and I went to pass someone. I hit 85mph and was at about 4100 rpm all of a sudden when it started hesitating real bad. Doesn't feel like a single cylinder miss. Kept driving and it smoothed out. Then after it sat for about 30 min I drove it and it was missing like crazy for about a minute then cleared up with just an occasional hiccup. So far it seems that it gets bad after sitting then sorta clears up. What could of triggered this just from passing someone. I check MAF and FI connections and they didn't make any difference

did you check those items yet? my car kept hiccuping and it turned out to be a bad TPS hardswitch. reason being, it never gave me problems at idle (when the switch was supposed to have a closed circuit) but would give me problems any time i was off-idle.

odd I went to go look at the cap and rotor. I noticed there was what looked like dirty water spots everywhere. Looks like the engine was getting wet everywhere. I checked and haven't lost any coolant.......odd

look at the connector ends of the spark plug wires. Do any of them look pinched in? if so you can use a flathead screwdriver to expand them out so they make good full conact with the disty, receptacles and the one to the coil as well.

I agree with the throttle position sensor idea. That SOB can wreak havoc on your idle, shifting issues for the transmission, and most likely a cause for erectile dysfunction.
It can be adjusted. A little turn can make a BIG difference. Turn, drive, turn, drive, etc. till if feels right.

will most def take out my throttle body clean it up and see if its dirty it makes perfect sense. frist time running this engine sense it came from teh junk yard and drove 300 miles on it so far. and dont worry i change the oil, spark plugs, wires new disturbutor cap, and fuel filter. and thermostat too and all the belts. also did a proflush. added lucas heavy oil stabilzer. and drained it after 75 miles cause it didnt do any thing. then another oil change with engine restore AMAZING!!!. and now after 300 miles on it im gonna do a Dura Lube additive in the engine cause pops said so eh. lol cant question the old g's in mechaincs lol

so i cleand the ivac and then the throttle body and advance the timing a little by turning the distubutor. the car when starts up cold idles at 1300rmps then goes down to 1000 rpms and once it warms up to 900rpms... i turned on the heat full blast the head lights and step on the brake and put it into drive and it idles at 500 and feels like its about to stall.... can somone help with this problem..

DO NOT USE DURA LUBE!!! stick with the engine restore. leave it in there for the full 3000 miles. that stuff worked miracles when i had my honda and acura.
if you have the gxe model you can adjust the idle on the ecu and the iacv itself.
my maxima idle's at 400rpms...thats with out anything on. dont feel any vibrations, or does'nt feel like she's about to stall either.

gradually loosen the idle adjust screw on the iacv (underneath a black rubber cap... well assuming you have a VG) until your idle is satisfactory. there's a more complicated way to do it but try that first.
