Hey guys. I have a '74 Triumph Spitfire 1500 that I've owned for about 15 years. It's been a great driver with very few problems. About a month ago when I was driving the car I felt a little "skip". I thought nothing of it at the time, supposing it was just some trash in the system. The next few times I took it out the car would drive fine for about 10 miles, or so, and then the "skip" (skip is the only world I know to use, it actually feels like the car is not getting fuel for a few seconds) again. It would then run fine, but about 5-6 miles later the car would "skip" in a series of about 4-5 times in a row, actually feeling as though the car was not getting fuel and about to stall! Afterwards the car might run fine for a while and then "skip" in the series again. Recently I've done some maintainence... oil change, new fuel and air filters and spark plugs. Over the weekend a relative who used to own a Spitfire told me he thought it could be something wrong with the gas tank venting. He took off the line from the carbon canister and blew into it. I took it for a test drive and it actually seemed to run better for about 20-23 miles... but then would suddenly "skip" violently many times as though the car was gasping for fuel. It acted up all the way home. I got it home and let it idle and it did the same thing, seemingly gasping for fuel, and would actually die if not accellerated. Can anyone help me? Also, is it really necessary to attach the venting hose to the carbon canister? My relative told me I could just cut the hose off so that it vents in the trunk.
