Got some new injectors from a dodge neon 4-hole and put them in my fuel rail....now they don't fit....I thought this was what suppose to go in from the tons of post I was reading. Should I put the old ones back in (I really don't want to because they have a small crack) or is there a way to get these in and still be ok?

Alright so since I didn't want to modify my fuel rail or put anything back (because the old injectors were cracked), I walked down to my buddy's house and asked him what he thought. Turns out his daughter had a junked dodge caravan that they were gonna sell for parts I asked if I could look at injectors and see and he said sure.

For some reason, the car didn't have 6 injectors....I was very confused lol, but anyway, I got five nice injectors that fit my vehicle and they were 4 hole. Long story short I only had 5 good ones so I walked home to contemplate my plans. I had one non-cracked one hole injector and I cleaned her up nice then I took the 5 injectors and 1 stock injector and put them back in. reset the computer etc......... started her up and she sounds nice.......NOW MY QUESTION IS how bad is this to have that one injector 1 hole and the others 4. Lol I know this is a long story, but to understand You have to hear the whole thing. Thanks!

I don't know as far as "how bad" but I would say your efficiency of burn will be the biggest difference. After driving it a little while just pull a plug from one of your 784s and then the OEM injector plug and compare your burn patterns. I would certainly pick up another 784 when you have the chance if I were you. My OCD would kill me even if they were equally as efficient.
