Egr

Okay. So I have a misfire still at idle and the mechanic said that it may have a leaking egr valve. So my question is, is there a way to tell if it is leaking?, could it be a leaky gasket? Or should I just get the whole egr valve for $64?

if you have an egr leak its usually pretty easy to tell, you can see/hear it.

I'll try that. Hopefully it warms up so I can do this. Mechanic said a leaky egr or bad injector on 2

i don't see an EGR really causing a misfire unless it's completely clogged but you'd be throwing a code for EGR flow insufficient in most cases

If its leaking, you'll hear/feel pulses of exhaust around it, usually you'll see water spray out

Then I don't think that's my problem. I'll still check it out before buying anything lol
