bad injector(s)

[holokosta]

So my car threw a code the other day and once i hooked up the reader i got an "injector circuit relay" code.

So i'm running Techron through for 4 or 5 tanks and its helping but if it doesn't fully fix my problem I think i am going to do a whole set...

any advice on sized and brands i should think about? I know that I currently have upgraded injectors but im not sure what i have (the joys of buying someone elses toy). SO best next thing, buy all new ones.

Any ideas?

What color are the ones you have? I know a lot of people use the Ford injectors

Unless you can tune and log your af etc. get a stock replacement but make sure it's an injector and not a plug or wire on the injectors.

The plugs and wires were checked when I had the opti replaced. Just when he went through the car right after I purchased it in general. By he I mean my mechanic btw. Good info though if he hadnt gone through it. Thanks.

injector circuit relay is just as it sez a bad relay. or the circuit to it. its common. its inside the underhood fuse box. about 30 bux at the dealer. dont go doing injectors wen its Not an injector.

Would that cause my bad idle and terrible fuel mileage?? And why would the light come off after I run the techron through it??

I'm not arguing I'm just trying to diagnose and understand. Im gonna look under the hood tomorrow and be sure because I would rather it be tha than injector believe me!!!

yeah if it was a bad/open injector you would have a bad skip ALL the time. if it was dirty injectors and a miss fire you would have a miss fire code. not a relay circuit code. the relay is probably bad and turning the light on and your getting less voltage to the injectors. try using a volt meter and see how much volts you get vs. battery voltage AT injector connector. Each cylinder.
