I installed new fuel injectors and it made the car run shitty. Is there some kind of preporation i need to do before installing them. Because it is basically plug and play. If anyone knows please tell me. Right now I am going back to my old ones which werent that bad in the first place...please tell me

 

What size were the injectors that you installed? If they were bigger than stock, then more than likely they created a rich condition in the motor.

 

yea u gotta let us know what size, but redline is right, if u got bigger, ur probably running too rich, and would need some kind of management to lean it out a little. For ex. a vafc, or safc

 

Hopefully you're not leaking any fuel. Did you replace the O-rings and apply a lube when you reinserted the injectors in the rail? I ripped one and had a nasty fuel leak and didn't know about it, made it run and hesitate like crap.

 

they are stock injectors..... I got them off EBAY so i am thinking it was a ripoff to get them. They are the same as my old ones....right now my friend is changing back to the older ones. But they are stock size....CRX SI

 

All the gaskets and rings are replaces and we did lube everything. My friend is a professional mechanic, i am just confused (he is working on it right now) but i just wanted to know if there is some kind of prep before installing them. Now it drives with them in but around 25000(rpm) it starts to haul and PUT kinda sound ya know. And sometimes the engine light comes on and it runs shitty all the way through, but i turn the key off (car still running) and turn the key back on and it runs back to normal hauling at 25000.

 

I would get the injectors you got off of ebay cleaned and flow tested to make sure that one or more of them isn't stuck open or inconsistently spraying.

 

do the injectors click REALLY loudly, (your old ones or new ones)?

I've noticed mine are the loudest thing on the engine.
