I have 73 1.7 engine that had green injectors installed incorrectly several years ago.
The green injectors are for a 1.8 or 2.0. The green injectors also spray too much fuel. After I replace the green with the correct yellow injectors, is there any engine adjustments I need to do? Thank you so much in advance for your response and help. |

Check with Bruce Stone. He has plenty of yellow injectors I think still.
I suggest you check the MPS for vacum and have the injectors checked cleaned and flow tested by a reputabl vendor like Witchhunter or others listed here. When they rebuild the pintile caps they don't always use the same color. I had mine rebuilt and the caps are black now. Most important thing is that they are injecting fuel with the correct rate and with a good pattern and NOT leaking around the base. If you haven't done this in 15 years........Time that you did. Check with Bruce. |

Good Advice! I have already sent my injectors to Witchhunter and they did a great job on the rebuild. I also replaced the elbow hoses to the injectors. I also got some good FI clamps too!
