Alright! I got my injectors back in the mail, woohoo! Problem solved and they are all working like new. I was worried I would be replacing them.
So as you can see my injectors were in horrible shape when I took them out. The pintel caps were all cracked and not suitable to use under any circumstances. I looked through many sources for replacement parts and they are super hard to source. Even if you do find the grommets they are expensive. I gave up and decided to send them to a professional seeing how they are vital to the engines performance. I was worried about how well they would work because they are so old so I definitely wanted to get a professional opinion and a proper cleaning. I was pretty weary of who to send them to because I've seen people charge $40 a piece just to clean them... and then they take a couple weeks and you don't have any proof that they even did anything.
I read a post from a person that had a rough idle in his Tundra I-Force and no one could figure it out. So he took out his injectors on his own and sent them in. His truck was only 4 years old. He sent them to Witchhunter and all his problems were solved. After seeing his printout from his relatively new injectors I knew I had to send mine in for sure.
After a lot of searching around for a professional and reputable fuel injector business I found the best in the business - Witchhunter Performance.
I spoke with the owner, Gordon, about what I needed before I sent them in. He assured me that they would be serviced correctly and all the grommets, o-rings and pintel caps would be replaced without any worries. He had all the information on the website to explain exactly how and where they are to be packaged and shipped. He even has tips on injector performance and how you can help them stay cleaner longer. Make sure and give his website a read. I have never seen as much specific information on a website and no mechanic I have talked to knows injectors well at all.

I sent my injectors in on the 15th of this December by USPS priority mail and they arrived back to me yesterday December 23 by USPS. Not bad! On the shipping invoice he shows record of the arrival date as well as the date the injectors are shipped. Also noted on the invoice was the comment, "Turned out good, were in bad shape upon arrival". Both true. The total for my 8 injectors being cleaned with new rubber was only $127.50 which is an amazing deal in my book.
I have no doubt in my mind that the engine will run better after this cleaning. This is probably the cheapest way to improve engine performance. Here are my results:
A big thanks to Gordon over at Witchhunter.
