Hello All
My 95 272 Barchetta is running a little bad?
I thought it was bad gas. I changed the fuel filter everytime out, and have added some heat to the fuel tank, I must say it is running better, however, I've put in an additional 30 gals of gas and it still is not great.
It seems like when you first start out (cold) it runs great, in five minutes or so, its wont idle very good. Some times when you are on plane and hit a rough spot it cuts out then catches and go's?
It seems to labor in and out on low speed , on hifh speed its a little slower than last year, but not that bad.
Its a 454 with cross ram fuel injection. I was wondering about the dist cap, wires, and plugs?
any advice?
thanks

I really dont know about the fuel injection but with a carburated engine you would be most likely looking at the choke being stuck closed. It richens the air/fuel mixture when the engine is cold and leans it out when it is warmed up. If the choke is stuck closed when its warm it runs poorly. This might give you a direction to head in.
