97 HARDBODY SPEEDOMETER STILL ACTING SLUGGISH ?????

[DONMC]

I HAVE A 97 4 CYL. 5 SPEED STD. SHIFT 4X4 . I'VE CHANGED THE SPEEDOMETER AND INSTALLED A NEW SPEED SENSOR . THE SPEEDOMETER STILL ACTS SLUGGISH AND FLUCIATES. FOR THE FIRST 4 OR 5 MINUTES WHEN YOU FIRST CRANK AND DRIVE IN THE MORNING IT WORKS NORMAL. I'M TOTALLY STUMPPED, I CAN'T BE THE ONLY ONE THAT HAS OR HAD THIS PROBLEM. ANY SUGGESTIONS WOULD BE GREATLY APPRECIATED THANX DON

My hardbody does this as well. Was told the speedometer cable is worn out and needs replaced. Hope that helps.
