Hey guys, I've got a 94 Impreza that likes to surge when you are driving down the road. I cant for the life of me figure out why this is happening.

 

has this happened to anyone else? and what would cause it?

 

Thanks!

Any recent work done?

Plugs, wires, filters, PCV, when were they done last?

Check engine light on? If not, does it work during the bulb test?

So to do the light test you just connect the green connectors under the dash?

To do a bulb test you just turn the key to On.

 

You connect I think the black plugs under the dash to read stored codes. If the Check engine light isn't on, there will probably not be any codes stored.
