In Portland there's a place Automotive Products.
They check em for $10 each.
Clean and repair for $22 + parts each.
Just had all 4 of mine done and it ran $135 all together.
They are all matched up now and the flow is better than original at around 362cc compared to stock at 317cc.
Also I've included a chart I found with injector part #s and details
