I'd have to get a longer piece of vac line and watch it I suppose. Is there something I should/should not see? I'm not sure about the pump shot, though. I can't even rev it to a steady 2500 and ease the clutch out. It'll hold at 2500 no problem while not moving, but as soon as I start to ease the clutch it'll fall flat immediately and the only way to catch it is treadling the gas (more pumpshot, I suppose). This one's really got me stumped (as if I wasn't having enough problems with this car these days). The other weird part is the fact that it's somewhat intermittent. Occasionally I can ease from a stop at 900 or 1000 rpms no sweat, barely any throttle. Other times I can't get it to leave at all without lots of pumping the gas and feathering and bucking and stumbling. I still think it's a fuel issue at heart, but damn if I can figure out how. |
