Check on the parts forum, ebay has some sometimes. All the injectors may not be good on that other engine for 700. You can learn how to test them on q45.org

Dont buy a new engine jsut for injectors. Check out deatsch works as well as used ones.

NO way all 8 injectors are bad if the car still runs. I bet like 3-4 are bad and whoever is selling them to you wants more money (dealership?)...

Buying a used fuel rail with 8 injectors pretty much guarntees youll have 4-5 good ones, maybe more.

thats what i thought. Its my girl car and she holla they tested it at the dealership(diagnostic) and they said all 8 were bad. Im like is that possible, they probably just want their bread. But whats deatsch works. Btw, the engine for 700 had like 25-35xxx on it from the same website i got my acura legend engine for 500.

I wonder if they are reading the ECU code 45 (might be 51?)- leaky injectors, or are they ohming the injectors at the harness to come up with their diagnosis. The leaky injector code means you need O2 sensors, it has nothing to do with injectors. Go figure.

You really need to ohm the injectors yourself to make a smart decision. The instructions are in the tech help section at Q45.org. Takes 5 minutes and all you need is an voltmeter.

If they just plugged in a Consult it tells them nothing about the ohms resistance of each individual injector. They probably did get the leaky injector code. As you said, check them yourself. Let us know the results.

It may be a good idea to buy a set like Q45denver has, swap the entire shootn'match out and have the ones in the car now as spares.

However, I bet you have 2 bad ones bad, 3 at the very worst.

You absolutely must swap the engine and then give me your old engine for only the price of freight to get it to me. I can de-activate its hydrostatic rod safely and dispose of it once that's done.

In all seriousness, just check your injectors and replace the bad ones if there are any that are bad. The '94+ injectors don't go bad as often as the earlier ones.
