E36General discussion and technical help for (E36) 1992-1999 3 series cars. 318, 323, 325, 328.
Just bought & installed new fuel injectors- all 6 of them, at $87 a piece. But wow, what a difference, the car runs fantastic. I just hope this will help with my emissions inspection next week If not, that'll definitely put me over the top for a waiver
did you have any problems with rough idle or anything before? does the car have more power?
No, the car was running amazing, but there were some problems: bad gas mileage (about 14.7 mpg), and my emissions test showed high NOx and slightly high HC's. Also, my plugs were always fuel fouled when I pull them, so I had to be running rich. I'd done everything else imaginable, and the injectors were the last thing. I'm thinking they were leaking into the combustion chamber. I guess we'll see in a day or two if these issues clear up. The old injector tips didn't look bad, but you never know what condition they're in on the inside. As far as the difference I feel, the engine doesn't struggle as much when I hit the gas; it feels a lot more balanced now. So yea, it feel like it has more pep & power, more responsive.

Not at all, I changed all of them in about 45min. 3 tools: a 10mm socket, a flatblade screwdriver, and a curved needle nose pliers. The curved type works better than the standard needle nose- you can get in there a lot easier to pull the clips off, and you can use it to push the injectors off the fuel rail. The last injector by the firewall is a bit of a bear to install as there isn't much room, but it just takes an extra couple of minutes.
Well, I imagine you'd get much better mileage where you are. In my town every single light you come to is red. No exaggeration. It's about 2mi to the outskirts of the city, but it takes me about 15-20min to get out of town. Plus, it really sucks living near the Holland and Lincoln tunnels, all the traffic eats up your gas

I keep forgetting that - I have a great memory but it doesn't last long
