Fixed it! Problem was pretty simple, i let a mustang guy help out on the install and he gaped the plugs, must have no idea how to gap plugs because i told him .035 and they were at .020-.025! after taking them all out and changing the gap car ran great.


What can we learn from this? NEVER let a mustang guy touch your car

 

He probably did it out of jealousy for not owning his own F-Body!!

 

thats what im thinkin
