So I recently replaced all 6 fuel injectors. After that install the car ran great and the only issue was one leaky injector. So I pulled the rail again and replaced that injector with another new one. After that I've been getting horrible gas mileage! A 50 mile trip now eats up an 1/8th of a tank. What could have I screwed up??

Thanks!

 

regulator could b cloged causing higher presure to be put to injestors causing more fuel consumption

 

Well I it looks like a sensor came loose. I believe it's the temp sensor, but haven't had time to check the FSM and confirm. However the engine is idling better after cleaning the contacts and reseating that connector. Gas consumption seems better but will have to drive it a bit more to confirm. I'll also check that regulator just to be certain. Thanks!
