So I have a 99 Chevy lumina 110K in miles.....well since I had the car I
got a tune up, fuel filter, MAF sensor, fuel pump, new coils and last
but not least the most recent a new egr valve. So to make a long story
short I was having trouble with the car cutting off on me sometimes so I
took it to Goodyear and they ran some tests and they came back with the
conclusion I needed a new fuel pump (reason why it would shut off
sometimes) and also a new egr valve (reason for the rough idle) so now
it doesn't cut off on me now but even though I replaced the egr valve i
still have a slight rough idle. Like I can feel it in the brake petal
when I'm stopped at a light, etc. and I can hear the car just a little
def. not how I want it to sound but not real loud. Please help what
could possibly be the issue now. Thanks
