When i accelerate my 98 blazer it seems like its giving to much gas and it dies on me but it will start right back up again. need to accelerate slow

SOURCE: 98 Blazer won't start

try buying some starter fuild. if that dont work try checking the gas filters. if thats not it your erg value may have a carbin build up. that will need to be clean out. but most of all make sure you have spark

If this engine is a VORTEC then you may have a problem with the internal fuel system. Under the top plenum there is a fuel reg and poppet valves that inject fuel into the cylinders. Sometimes the tubes that run fuel from the reg to the valves can leak and cause your problem. This cannot be found with pressure check because this occurrs after the reg. PS fuel mileage will go down. Let me know if this helps.Moe

the only way to tell for sure is to have the engine anylized with a real time scanner, it could be a sensor or actuator that is not throwing a code so a scan for codes will not help, if all seems to be od start looking for vacuum leaks, air bubbles in the fuel, fuel pressure constant, etc
