Engine Performance problem
1995 Chevy Tahoe V8 Four Wheel Drive Automatic 160k miles
Truck run good, except when I let off the gas it makes a whoo whoo whoo sound for a couple of seconds then it levels off and drives good, I mash on the gas it takes off like a rocket, but when I let off the gas it does that little sputter for a few seconds then everything is fine, I'm thinking egr valve, but I just don't know, I checked for vacume leakes, can't find any, new intake gaskets, distributor cap & rotor, plugs & wires, valve cover gaskets, I assume the timing is correct or it wouldn't idel and run as good as it does. I brought the #1 piston up before I started the intake gasket job, it fired right up after the job was done no problem. It dosen't sputter like that when I rev it up with the transmission in park.
have the same problem?
