LOW IDLE

2000 Chevrolet Silverado • V8 4WD Automatic • 153,000 miles

I have a 2000 silverado with low idle, I have all ready cleaned the massive air flow and took the throtle body off and cleaned it, replaced the plugs and wires. RPM's in drive will go down to 300 or 400 rpms, have replaced the IAC and the tps senser. Nothing seems to help.
