SOURCE: 96 Nissan Maxima continues to have engine light

I had a similar problem - took it into 'Nissan Professionals' and they changed everything you did as well, and had no luck. After 4 or 5 times working on it, they told me that it was a 'loose wire' that had to be re-soddered and then the problem was fixed. I don't know where the wire was, but they made it sound like it was in or around the fuse panel under the hood.
I hope this might shed some light on the problem.

SOURCE: 82 buick riviera getting steamy oily air in air

That is blow-by from the engine. That means that the valve seals are going bad and a head job needs to be done.

SOURCE: WHERE IS THE VATS PASSLOCK/PASSKEY SECURITY SYSTEM

Normally the TDM (Theft Deterrent Module) is located behind the glovebox and tucked in the frame just a little. Here is a link that may help you with this problem

It should take care of itself if the engine is running - can you tell if the electric pump in the engine compartment is running ?

When I crank my car my idol goes above 2 and then falls down below 1 and then it does a couple of times and then it dies sometimes. when I'm driving & stop and then go it sputter & idol does again

Try changing the tpi throttle positioning sensor found on the throttle body . Check air filter, clean air mass flow sensor.located sometimes in air box ,or after going in throttle body black hose, going in air box usually found in those two spots. If no change. Then I would check o2sensor start whith the cheapest first.
air box / hose going to motor look for a set of wires
unplug wires and pull out clean or replace. Spray whith brake cleaner starter fluid or similar.
Tpi throttle posistioning sensor.
last but least
o2sensor sensor.

My 2001 Malibu seems to have a throttle problem. It sticks at 1500 rpm when at a stop light and will hold at 42 mph when in motion. I had a fuel cleaning service done, tune up, intake gasket, fuel...

are you spraying it in the intake at the throttle valve.if so then you need to clean the throttle valve thoroughly front and back.have you checked the throttle cable for rough spots in it.its more likely its just a dirty throttle valve.

Engine dies out above 2500 RPM, picks back up at 2000 RPM

That's a characteristic of Nissan engines when the mass airflow sensor is not working. My 1990 300ZX was set up the same way - when the mass air sensor fails, the car won't rev above 2500RPM in order to safeguard the engine. Get some air intake/throttle body cleaner and clean the mass air sensor. Get some electrical contact cleaner and clean the electrical contacts on the harness plug that plugs into the sensor. If that doesn't cure the problem, you'll need a new sensor.

The mass air sensor is in the 3-4" diameter pipe between the airbox and the throttle body.

Could be. Check the wiring at the oil pressure sending unit. If the wiring is good, replace the sensor. It is located Under hood, passenger side, rear engine area, above oil filter, mounted on lower timing cover. Curtorsey: Auto Zone.

1990 ford probe-Changed air filter now it won't idle at all!

Check the connections to your IAC (idle air control) valve and or remove it and clean it - do the same to your MAF sensor located just behind the air filter box, you will need CRC mass airflow sensor cleaner and a T20 torx bit, look for vaccuum leaks as well

1990 corvette

Try clamping the fuel return line with the appropriate tool that wont damage line and see if it improves if so you need a fuel pump or pressure relief valve.I know you said you had fuel pressure but you took that reading while vehicle was idleing so you cant check for pressure in above idle conditions.Is your air cleaner assembly as original with no holes or leaks from air box to throttle body?Its more likely to be a mass air flow meter.This problem occured to my vette while i was on holiday there.cost$89 exchange.good luck
