You remove the head bolts from the outside inwards, criss crossing to the middle. This is the opposite of reinstall which is centre to edges.

Your 2000 Frontier only has the one TPS sensor.

The problem is either the trans/bell alignment, or the pressure plate's installed height,

underneath intake manifold between cylinder 1 and 2.

Hi there Francis,here's a link to your code.

PO 304-- is a misfire in cylinder # 4

You can Google any codes you get

PCV Valve- if you knew what one was,
has to be on the valve cover, to keep
oil in the crankcase from entering the
induction system

It has an orifice tube not an expansion valve. Follow the high side line from the firewall back to the radiator. There should be a fitting a couple bends back from the firewall. Take apart the line at that fitting and the orifice tube will be inside.

You probably inserted the pump wrong. The timing mark on the balancer must be at TDC. Then when you put the pump in, the rotoe should point in the direction of #1 cylinder. If you know that you had these things in order, you probably need to turn the crank one turn. If you set it up with an open valve instead of both valves closed, you are exactly 180° off. Tou can turn the distributor 180° and see if that helps but, it will mess with anyone else that would ever work on it.

Behind the glove box in the air box right next to the evap.
