Can anyone offer some info on where to purchase new or rebuilt injectors? the stock ones are $180/piece. I cant find anyone in north Alabama who knows what i'm talking about when i say "ultrasonic cleaning". Even the dealerships.
i've had a lean code prob and when i changed plugs again i noticed a white cast on the passenger plugs.
I thought i'd give a go at changing the passenger injectors since their pretty easy to get to.

changed... o2 sensors, cleaned maf, fuel filter, pcv valve, listened for vac leaks, new tps.

 

Have you cleaned your MAF sensor yet?

What was the exact code # you got?

 

yeah.......checked the maf AGAIN lol
p0171 bank one lean. i cleaned the maf again the other day and checked the hot wire, but everything looked great. i'd changed air filters the last time i cleaned it as well.
it's really cold natured now as well! and kinda surges around 2k rpm's after it warms for a while.
anyone ever changed their engine coolant temp sensor?

 

Take the MAF/IAT module off again and this time really clean the MAF hotwire, not just the IAT sensor.

 

vacuum leaks cause lean codes too . . . check the lines for a disconnection or cracks.

And run some Techron injector cleaner though too. It helped my 2nd gen. Be sure to get the "techron" not the "With techron"
