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.

thanx

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"
