ok, last week I got a code 45 from my ecu (leaky injector or something) and the light came on every time I hit the peadal. I put some lucas injector cleaner in my tank and it cleared up I re-set the ecu and checked back frequently for new codes.

tonight after work I noticed my Idle a litle low so I popped the hood to turn it up. under the hod I hear a sharp, fast paced but not loud clat-clat-clat sound. it sounded like it was coming from the air cleaner box.

I noticed the niose is in rythm with the pusling in the fuel line from the fuel filter. when I rev it the pulsing steadys out (slower rythm) and the fuel line pulsing is less dramatic. I assume it slows down becuase the injectors are spending more time in the open position.
anyway, has anyone dealt with this before?
are my injectors going bad on my TBI?

ok I took off my injector cover and fount out that the passenger side injector is the culprit. I noticed an ajustment screw on top of the injector. (I can't keep my hads off anything) tightening it made it quieter and my engine sounded smoother. then it came loose of its seal gushed fuel everywhere doh!
I shoulda put the injector cover back on each time to keep it from poping up. I rigged the throttle open and let it vent for a while and while waiting, I decided to polish the little injector cover. I got all the pits and factory molding marks out of it with an air tool and a scotchbrite disk and got it to a near-mirror shine. then I put it back on, pulled the fuel relay and cranked it till it turned over. It ran for about a minute when it did and left a nice puddle under my tailpipe. (there goes $10)

Anyway I checked parts america and they have a few choices;
Niehoff
Python
BWD
Standard Motor Products

I looked up python because they are outa the norm compared to what I usually see for my repalacement parts and they seem to be a perfomance injector company. so I'm thinking I might go with them (not the highest price either) anybody got any other ideas or reason not to go with python?

Nothing wrong with a used unit, but python is a very good company for anything FI related.

I just found out that neihoff& Bwd are owned by SMP so from parts america ist python or them lol
tha python is actually a reman with a $60 core return (making it the lowest @ 280 after return) so I'll prolly go with that.

I dont't mind used parts too bad as long as they work but there arn't too many nissans (esp tbi) in the JY arround here. and on the bright side if the first ones lasted 18 yrs hopefully the new/reman'd units will last another 18
