SOURCE: 96 pontiac sunfire bogs down and dies when I apply the gas.

as far as the bogging and dieing,it sounds like the tps.a simple trottle body service would fix that.for your new problem you need to some test before pointing to a salution.start the car and cover your tail pipe.as pressure builds it push you hand off.a clogged cat will put to much back pressure on the engine.i would un plug the mass air flow sensor and try running the car.this will turn on the check engine light.check your air filtter and plugs.also check your wires.a nother test is a coil strees test.(you have to go to a shop for this)if the car runs ok with no load but spitts and sputters in drive you may have a openning coil.checking with a meter only works if it does not run.last but not least while you at the shop,have them check your timing.a faulty cam sencer will bog the car down with bad timing advancement but not throw a code.
hope this helps,remember to keep it simple,expensive elec. parts are not always the problem

SOURCE: no acceleration

I had the same problem with one exception. It would rev higher than 3500 but the higher it revved the more it bogged. I had the catalytic converter replaced. I thought I bought a new car. Acceleration is just like new. It was easy enough to test. My mechanic cut a hole in the exhaust pipe in front of the catalytic converter. It sounded like a truck but the acceleration difference was immediate. Easy diagnosis.

The car is hard to shift because the more you press on the accelerator the more the computer for the transmission won't let it shift. Which in turn causes the car to bog more sending more unburned fuel into the catalytic converter. Which in turn causes more carbon build up and more back pressure. Vicious cycle. It will only get worse.

My thermostat caused the entire problem. Thermostat was stuck open, engine never got to operating temp most days. Car burned rich. Bad gas mileage. A lot of unspent fuel being dumped into the converter. Probably have some underlying cause that needs to be addressed. Bad plugs, wires, coil, fuel filter.

1985 Fiero: headlights will not go back down...


Fiero headlights are headaches, especially the early years (84-86). Be glad they are stuck up and not down!

Does it make a grinding noise or anything while trying to go back down?

If so, the internal nylon gears are worn and need to be replaced with metal ones and good lithium grease.

If no noise while trying to go down, then it's a power problem. Check the blue connector going to the headlamp, careful in this area, they motors can turn on/off suddenly if the power is restored to them. Don't get your hand caught in there!

There are also relays to check, 1 for each motor and 1 main one for the headlamps, get a haynes manual to find them. They are little black boxes.

Also, could be your on/off headlight switch, take it out of the dash to see if wires are loose.

There are lots of forums online about these headlights and how to fix them. Look around and good luck!

Removel of fuel pump on an 1984 pontiac fiero se


Remove the fuel tank, sits under the car, looks like a casket.

You actually sit to either side of it when you're in the car, that's why it has such a big hump in the middle. Any GM fuel pump works for it.
