    thanks, haven't found any vacuum leak, think narrowed it down today to either computer sensor problem or fuel pump, noticed fuel pump not firing on during pre-ignition, but also found aconnector at ignition coil not getting power,,,,?

Try looking for a vacuum leak,could be any of the other things you mentioned also.Check if your distributor is points or electronic and is it carb or injection.What tests have you carried out?

    Iforgot to mention that the cruisers had a thing about valves sinking into the head and require periodic resetting.It If you have no joy with other fixes check valve clearance

Do you have tbi or the spider fuel system. That spider fuel system is noted for problems. Did you use a gage and check fuel pressure? For tbi it is 9--13 psi. For the spider fuel system, it is higher.
How many miles on your engine? In park or neutral, not much load on the engine. There is a load when you put it in gear. Can you do cylinder compression test to see if compression is ok? I believe the highest reading to the lowest, all should be within 75% of each other. A generic spec. Maybe a 100 psi min. spec

Engine stall when put into gear.

There are a few possibility on this one. If you run it out of gas or really low on gas you could of sucked junk up from the bottom of the tank and you will need to replace your fuel filter. Another is that your fuel pump us going bad and you would need to check the pressure. Your throttle position sensor may have gone bad. Your idle control valve is another. Your map sensor or mas sensor could be bad

2001 Nissan Altima idling high in parking or neutral

I have the same problem with my harrier 3000cc car. We have changed the idling sensor, airflow sensor. air filter, we have had the throttle checked, spark plugs, wiring and nothing works. The smell you are getting could be from your gear box, have it checked out early and if the gear shift is noticeable then you will need a gearbox specialist to open it and change the clutch plates. Good luck.

Do you know what engine scan data is ? Disconnecting sensors is not the way to find a problem ! What is the computer seeing as data input signals . Is the vehicle in closed loop fuel control , is the EGR opening when it shouldn't be , Is the PCM controlling the idle air control valve or is the vehicle drive by wire (electronic throttle control ?
