Bought a 4 cyl plaining on driving it intel I build a motor but it seems like it runs on 2 cyl sometimes it doesn't do it all the time and I changed the coil packs and wires and plugs any ideas thanks

 

Is the check engine light on

 

Yes it is

 

I would say you should take it down to a shop and have them pull the codes off it. It could be a number of things.

 

Yea the person that had it before me did that and they said it was the coils so I change them but it still does it don't no much about these 4cyl I am a 5.0 guy this is my fourth mustang first 4cyl and third foxbody

 

Do the 4 cylinders come with turbos? Serious question..

 

Some yea not all have turbos tho
