I recently swapped a 92 straight 6 in my 91 4cyl jeep. I love the straight 6 but recently I've been having a misfire issue. Had code 27 looked into it and found one of my injectors wasn't firing. Made sure it wasn't my wiring so now I need a new injector. Well I googled injectors and tripped across upgrading the injectors. Crown automotive offers injectors for 45 a piece so 270 for a set of 6. Kinda pricy so I saw upgrading to the 4 hole ones work better. I have found some sites but has anyone seen these style injectors and or been to these sites? Does anyone have any sites they've gotten there's off of?
