When I'm driving it's like I take my foot off the gas and the reduced engine speed comes on

No codes? There has to be if you have power losss. If auto parts won't pick the code up then take to a pro put his scanner on it. It may be something with abs etc. Something has to causing this.

Not likely that is mechanical. Have battery checked for condition including load test weak batteries do screwy things now adays. Also pull dist cap and see if rotor moves if it does then the dist gear is worn out and you'll need another dist then a pro will have to set it in with his scanner so cam/crank sensor are in sync. Most places check battery for free

May be a stupid question but this is a vortex engine it has cool packs I don't see a distributor I guess there could be something wrong with the battery but I just put it in six months ago I've been dealing with this for three years

Is this a V8? Engine stuff doesn't come through on the new site here? If it is do a wiggle test on crank sensor and cam sensor the connector may be bad. Otherwise I have no other suggestions.

If it were a sensor then it would throw a code it may be the throttle body but without checking I don't want to have you buy an exspensive part like that.
