How difficult (time, special tools, etc) is it to replace the fuel injectors? Where is the best place to get them? I replaced my knock sensor and wire, that took a while.

 

When you replaced the knock sensor, you went right past the injectors. So you already did (once) 3/4 of the work.

If you just go out an buy new injectors, installing them is very easy. Don't forget to use gasoline on the orings where they go into the rail (as lubricant). DON'T forget to replace every crush washer. You'll have to open all the fuel line connections, and the crush washers are one-time-use. I've only found them at the dealer, but they are cheaper than dirt.

Injectors aren't cheap; about $150 each at online dealers. But RockAuto has re-man injectors for around $30! Ordinarily, I'd recommend some place like witch hunter http://www.witchhunter.com/ to clean your injectors, but even at $22 each the RockAuto remans sound attractive.

BUT -- you are likely to have a bunch of broken connectors. Some just zip-tie them back on (worked for me for years), but you can replace the connectors if you want to do it right. https://www.yotatech.com/forums/f116...ectors-290886/
