what are the symptoms of bad injectors?
my car is making a very loud clicking sounds coming from what appears to be te head. i took te head off and took it apart completely, and everything appeared to be normal.
the car won't run rich no matter what i do, and i have 440cc injectors AND i put my fmu back on to try to step up fuel pressure. i have an afc, and i'm leaned out 40% at idle, and up to at only 10psi i'm leaned out 15%.

usually my a/f guage will show lean/stoich at idle and normal driving, and go full rich at wot; but not anymore. is it possible for bad injectors to make a lot of noise? does it sound like that's the prob?

what other probs could these symptoms be?

the clicking sound started happening when i blew my head gasket and the temp needle almost maxxed out, so i'm pretty sure it's head related. what could it be?

 

possibly valve tapping? maybe you're in serious need of a valve adjustment...?
