Can anyone tell me what color the oem fuel injectors are on 89 GTA's with 350's. I am trying to find out if my injectors are stock. A picture would be great, if anyone has one of there fuel injectors on their 89 GTA. I think they are grey, i am away from my car right now so i am not sure. I could not find a part number on them, i have not removed them.

 

black

 

gray injectors are for the 305, 19#

 

Would that make a noticable difference? Could they bie for anything else other than a 305? I just bought the car and took it out for a drive and it didnt have that much power above 2500 rpms like my friends stock 87 GTA.

I just bought an adjustabel fuel pressure regulator along with alot of other tune up mods so that should fix it.

 

I just talked to someone from cruszinperformance and he told me that the fuel injectors for both 305 and 350 in 1989 were all grey.

 

mine werent.

Look at the bottom of the page they show the picture with the grey injectors as 89-92.

 

All 89 through 92 F-bodies were originally equipped from the factory with the Gray and Silver Rochester Multec injectors. 305's and 350's look the same but have different part numbers. They also have the highest failure rate of any injector due to the solenoid coils shorting out.
You would be better off replacing them than trying to have them serviced.

 

Yes, i was told the same thing by cruzin performance. I will replace them this summer.

 

I had about four sets of those Multecs... I used them for target practice.
