Fiero Problems

[Littlebabycar]

Ok, So the oil light/coolant light is on. I just did a coolant fluid change and oil change not too long ago and both are full. I was told it could be the oil pressure sensor. Only thing is, I don't know where that is. Could someone point it out for me?

Another thing, it has the 2.5 4cyl and it runs rough, like shake the whole car rough, but once you step on the gas it seems to be fine. I did a tune up (plugs wires, cap, rotor) and that didnt help. New fuel pump and filter as well. It just sounds like its running on 2 cylinders on idle and idles at 1200 rpm and will stall out sometimes when put into gear.

One more thing the transmission wont shift (its an automatic) unless I take my foot off the gas, I changed the fluid in it too.

Any help is GREATLY appreciated

With the radiator being up front and the engine in the rear, There is a special way to fill the cooling system. If not done correctly you can get air pockets in the system.

The oil pressure sensor is located next to the oil filter. Its about 3" long and about 1.5" in diameter.

As for running, have you cleaned the throttlebody and the injector?
Have you checked all the vacuum lines for possible leaks?
With the aircleaner off start the car and look at the spray pattern out of the injector. If it has a nice cone shape then the injector is fine. If dirty or bad you would see it spitting larger drops of fuel. It sounds more like a vacuum leak than a fuel problem.

For the transmission not shifting, There is a cable running from the trans to the throttlebody. This is the Transmisson Valve Cable. (TV Cable)

Whats the special way to fill it?

I have not cleaned the throttle body, and the injector seems to be working fine.

Is this cable also the be downshift cable? Because thats what it looks like and I just replaced that, don't know if I have it adjusted properly though.

Whats the special way to fill it?

1. Either jack up the rear of the car a little or park on a sloped driveway with the nose of the car pointing down.
2.(With the engine cold) Then remove the rear cap on the thermostat housing.
3. Then SLOWLY loosen the radiator cap up front. Any air in the system should hiss out. Once it is just leaking fluid, replace radiator cap and top off cooling system from rear.
4. Remove thermostat and put cap on.
5. Start engine for a few seconds then repeat steps 2 and 3. If no air comes out the front, Top off from rear, install thermostat, and replace cap. You are all done.

It is not a downshift cable like the old cars but it does look like one and it does need to be adjusted. Go to the link I posted above and here.

It explains how to adjust it and fine tune it.
