Under hood surprise
Just recently picked up a 94 TA with a recent new crank and bearings by previous owner. So far I've found a K&N CAI, flowmaster cat back, under drive crank pulley, and just last night found a MSD 6AL hid where the K&N filter sits down behind the bumper that was unhooked. Other than the recent crank, I have no idea whats been done internally though. Has a rough idle so I'm thinking it may have a small cam but not sure. Could be bored, could have a flash, who knows. I AM having a problem with it running pretty rich. Question I have is should i hook up the 6AL? Is there any benefit on what I'm assuming is a stock motor?
