My Blazer new to me 96 Vin motor W 150K miles sometimes will not rev over 2500 rpm. Took off from a red light and is boggy you have to feather the throttle to get up to speed. If I floor it it wants to stall put in nuetral and will not rev over 2500 rpm. I changed the fuel filter and fuel sending unit, new gas tank. It did not do it for 1000 miles and now it can back yesterday and went away this morning. It seems Fuel related to me. Befrore I changed the sending unit fuel pressure was steady 54-60 psi while driving and when it would bog pressure did not move. I change the sending unit pump and all because the gas gauge was not working and the tank had a leak. Does anyone know the specs for fuel pressure ? All replies Appreciated
