Icon4 RPM Gauge Acting Weird

the truck is a 1991 ford ranger xlt 2.3l 5-speed manual
Ok so ive been having problems with my rpm gauge. sometimes when i start the truck the rpm gauge will fluxuate and the check engine light will come on but the truck will be running pefectly fine. then the rpm gage will go back to normal. is there like a senser for the rpm gauge or something that helps the rpm gauge work. i need help. Also my speedometer is also fluxuating but it happens all the time.
