Bad miss (buck) at low rpm

burn rubber · 12-17-2003, 11:50 AM

whenever I am cruising at low rpms 2300 or lower i get a bad miss or buck. Any ideas what it could be?

It is probably your EGR. Thats the main reason most people delete it. Mine did the same thing.

Do this, unplug your EGR valve and plug the line so you don't have a vacum leak. Drive around and I bet it goes away.

If its not the EGR, I'm leaning towards the IAC valve.........

Any updates?
