My 84 380SE runs rough when it is cold. It starts up fine and seems to run not too bad until you try and give it some gas. As soon as you step on the throttle it sputters and will even stall. If it runs for 5 mins and warms up it is alot better. It still wants to hesitate a bit though. Any ideas? It has a new cap on it. It is a 3.8l V8.
Thanx
