Replaced PCV and Knock Sensor still CEL 850 1994

So I finally finished replacing both of my knock sensors, front and rear. As well as replaced the entire PCV system with the kit from FCP Groton. I am still getting a CEL with 143 in A2, which means front knock sensor missing or faulty. I am at a loss for what’s wrong. The car runs almost perfect otherwise, the only problem I have is this hesitation when you mash down on the peddle at highway speeds. The engine doesn’t sound any different it just seems to lag then finally free itself up. I know it isn’t turbo lag because I’ve had this car since new and this is a new problem.
Any suggestions to this would be greatly appreciated.

Thanks in advance.
