Hello! some time ago I've ask about this problem here, so I know if I have a code 51 I have a bad injector (or more) I have a used set of injectors with the rail from my previous engine ( I replaced my engine with a JDM about 18 months ago ) my question is, is there a way I can check if this injectors are good before installing them?

Probably I'm not going to do it myself since I don't feel confident about it removing all the parts to reach the injectors rail, so I don't want to pay someone to do the job if the injectors are bad.

My car registration is due on July 15, need to pass emissions and with CEL on will not pass, I need to get rid of this problem within the next 15 days, I'm on a very tight budget so I'm looking to save as much as possible, I would like to buy the OEM brand new injectors but I can't right now.

Do you have any suggestions for me? all help highly appreciated Thank you!

 

ohm out the injectors before you do anything. they should all read between 11 and 14 ohms.

 

I had a miss that progressed to a code 51. I pulled the wire harnesses off the injectors and sprayed electronics cleaner on the whole works and it cleared everything up. Took <10 min.

 

How did you unplug the injector thats right under the intake manifold???

 

Take your distributor cap off and you can get to it, just make sure your distributor cap is numbered, and you know and or label the spark plug wires so you put them back on in the correct places.

 

ok Ill try that tomarro, thanks alot

 

I'll give it a try cleaning my injectors, this time with an electronic cleaner, and I also had problems with that injector under the manifold so I'll clean that one too, last time I only brush 5 out of 6,

 

Well I tried to use that elecronic parts cleaner, and it seems to work. I sprayed out all 5 injectors, plus the TPS, and the Maf. car runs fine now!

 

Lucky you, I cleaned them today but my CEL is still there, I definitely need to replace my injectors

 

Yah, That parts cleaner works fine!! I know that Ive got one bad injector, but it kicks in most of the time. But Im gonna go ahead and buy some replacements since Ive got alot of miles on the car.
