A few days ago I was driving my car down the road and it started stumbling, it felt like ignition cut or fuel cut.. it happened for a few seconds then went away and I drove 80 miles home without a problem. Then it went a few days and is doing it here and there and when it happens the tach needle bounces up and down.

It does'nt do it and any one particular RPM or throttle position.

If anyone wants to just throw some ideas out there I would really appreciate it, I'm already considering the fuel filter/pump. And the Opti. If anyone could give me some more info it would help me a bunch. Thanks!

Also, before this started happening I backed into a curb and wacked it pretty hard, is there anything that's likely to come loose from this?

 

check the EGR valve, if it sputtered, it might be a clog
