Question about 1998 Chevrolet Tahoe
I have seen this type of problem before, this sounds like the engine is not getting the correct amount of fuel pressure it needs as you accel.the first thing is to remove the fuel filter and replace it, take the old filter and blow into it, this will tell you if its restricked. the next step will be to check fuel pressure, you will need a gauge for this test, hook up gauge at valve on the injector rail, take caution wear safty glasses as fuel is under pressure and will spary out a little as you connect line for the gauge to fuel injector rail valve, you will run the engine and also step on gas pedal as you watch the pressure, i would rev the engine to around 3000rpms and hold it to see if engine tries to stall or buck when it begins to act up look at the gauge and if the pressure drops as it starts to act up then the fuelpump is bad. its not able to keep up the pressure. start there good day.
