Sounds to me like your either your cam timing is wrong or your ignition timing is way
out. You need to take the top two parts of the timing belt cover off. Then turn the
engine over by hand until the #1 piston is at TDC on the compression stroke. Check...
1. That the timing mark on the crank pulley lines up with the dimple.
2. That the dimples on the cam pulleys line up with the marks on the back plate.
3. That the cam pulleys are correctly installed on the knock pins.
If those are all correct, remove and reinstall the distributor. Do this with the cap off
the distributor. Before starting look at the distributor with the cap on and when the
distributor is sitting with the fixing "ears" horizontal as it would be on the engine.
Lock in your memory where the pin for the #1 plug wire is on the cap.
Now take the cap off and stab the distributor according to the FSM. When it is all the
way into the engine with the ears horizontal, the brass bit on the end of the rotor
should be at the position of the #1 pin that you have memorised
If the rotor is too
far one way or the other, ease the distributor out until you can turn the rotor left or
right one tooth on the gear, and push it back in.
The PON cams do not have radical timing so there is no reason why you should not be
able to get a decent idle. And yes, the FPR does get its vacuum signal from the intake
manifold. There is usually a small black fitting with two or more spigots for connecting
the FPR and MAP sensor hoses.
