Hello US-Car driver I have a problem with my Chevrolet Tahoe 5.7l V8, built in 99. And that is: I have a gas system (Prins VSI) since about February this year (2008) in my Tahoe. Until now there have never been any great problems. But now to the problem which occurred today for the 2nd time. I go, and after 1-2km the gas tank goes on. Everything is normal. Since there was only very little gas in the tank, he switched off as always after a short drive, since everything is empty t! Problem, however, is that it does not run round in petrol operation! It runs like, for example, in winter, when the pipes are not really warm yet, so stutters all the time and does not bring any performance! In winter, this goes away after a few seconds, minutes (referring to the example!). But today (and a few months ago this was the same) it didn’t go away at all. Even when I am in stand (N, idle) lightly on the gas, no power arrived, but it stuttered everything n ur! When the problem came up for the first time it went away after a short time. Do you have any idea what that might be about?!
