Hello all. I hope someone here can help me out. I've got an 87 Blazer with tbi and when I really get on the gas, the engine bogs down, has no power, then slowly creeps back up. I've seen this problem a few other places but no solutions. So far here's what I've replaced: Fuel filter, fuel pump, plugs, wires, distributor, coil, coolant temp sensor and the gasket under the tbi. I advanced the timing and had two voodoo witchdoctors speak some unholy words with dead chickens. Sorry bout that last part but I think that's next. My next plan is to replace the fuel regulator in the tbi. Any help would be great. Thanks in advance.
