Does anyone know if a stuck intake valve on a "90" metro would cause the fuel to overload the the throttle body and blow out the top? I already know that the fuel pump works and that the fuel return lines are working. I also know that the throttle body itself is working fine and the fuel control valve is working as I have replaced both. Someone suggested that I may have a stuck intake valve but all three of the plugs are getting fouled or at least over loaded with fuel. So if its not a stuck valve would a timing problem cause this sort of problem? I feel that there is something relatively simple going wrong, perhaps a bad sensor. The thing is that I can get the thing started but it won't idle and I dont think it is a vacuum issue as I have checked and rechecked the vacuum lines. Also this problem happened very suddenly while driving it. Normally I would automatically take a look at the timeing belt but I was told that if the belt jumped even one tooth the motor would not start at all. So has any body ever encountered such a problem before and if so what was the problem.
Thanx in advance
