fuel injectors

[Kneiselc]

How often should you change your fuel injectors, if ever? My car has 113,000 miles on it and I doubt that they've been changed ever. I read the thread about the noisy lifters and it just got me thinking about this. If I should change them are there better ones for bimmers or just get OEM ones?

you can just have them professionally cleaned at like 50k-75k miles.and you should be running some injector cleaner every now and again.

Yeah I put fuel injector/system cleaner in everytime I change my oil but is that enough?

 

[flyinH]

that should be good enough unless you're experiencing some problems like a stumbling idle,rough spots at certain rpm's etc....

Great thanks, I do have a rough idle when I first start it and a while back I had a hiccup at 5000 rpm. I'll check more into it.
