Did you replace the insulators also? I think that is what they were called, but there are the insulators and o-rings. That should fix your problem. What I did when I replaced my o-rings was lube them with some 100% 50wt. silicone oil. You can use any weight really, but I had mine sitting around that I bought from the local hobby store awhile back. Its whats used in RC car shock assemblies.

About your idle... Have you tried to adjust your BISS idle screw? You have a 2.0DOHC engine so it will be on top of your throttle body. Make sure to ground the approiate timing plugs while you do this.

Good luck

Is your fuel rail bent or the mounting tabs bent causing the rail to not seat all the way in the bored holes?

yeah the insulators are different then the o-rings, theyre on the bottom of the injector, you can order them from napa or something theyre cheap. definately try replacing them

do the insulaters look just like the o rings cause when i got a set of orings for one injector there was one on top and one that goes into the fuel rail?

as i know the rail isnt bent but ill double check . thanks guys
