RB25. I checked my spark plugs:



I took the fuel rail off and out and I immediately noticed that #4 injector's tip was wet (corresponds to the #4 spark plug). I'm thinking that #2 and #4 are stuck open. Someone recommended a test:
How do I check each injector's individual operation? And is it possible to stop an injector from being stuck open? Should I just send them to deatschwerks?

I just found out that I can use a 9v battery to test them out...is this ok to do with the injector dry with no fuel?

noooo. prime the fuel pump so you have some fuel to cool off the coil. hold the negative side to one pin, then tap multiple times the positive till you hear it clicking.

do exactly this

Quote:
symptoms of a stuck injector would be flooding, gas smell from exhaust. best way to tell would be to pull the fuel rail, leave the injectors installed in it, leave the fuel line connected to it, and turn the key to the acc position. the fuel pump will then prime the line for about 5 seconds. if during this time any fuel shoots out, your injector is stuck open.

I meant to update the thread. I did exactly what you said. Thanks for offering help though!

I found that the pintle cap on #2 had a pin-hole leak, and the o-ring was completely messed up on #4. When I finally pulled all 6, all 6 o-rings need to be replaced. I'm going to send them to Witch Hunter tommorrow.
