A plugged air filter, low fuel pressure, etc.The clogged fuel filter and clogged cat.------- As per your problem mentioned, it indicates the problem with fuel pressure.-------- The fuel pressure is low.---------- First thing you can do is get the fuel pressure checked, this will confirm the problem. --------- If the pressure checked low that means problem is with faulty pump and clogged fuel filter. -------- But if pressure checked ok, then clogged catalytic conveter is other possibility, also try putting it in a low gear then check , if it works on lower gears, that means transmission gear slipping problem. Check your transmission fluid level it could be low.,.----------Also another test procedure you can try is, spray starter fluid on the throttle body and see if car starts and runs fine with starter fluid sprayed.Then it indicates fuel pump is faulty.--- Do this test when you face this no start problem.------- This will help.Thanks.Helpmech.

if engine at long stand still,the engine temperature will rise about 190 degrees the cooling fan suppose to automaticaly turn on when coolant temperature sensor get hot it cause its resistance decrease causing pcm to send power to coolant fan relays and cooling fans, when you turn on AC the cooling fans suppose to turn on to cool down AC CONDENSOR, IF NOT AC WONT WORK COOLING FAN COOLS DOWN REFRIGERANT SO IT CAN RECYCLE THROUGH THE SYSTEM AGAIN.your cooling is suppose to turn on when engine at a sit still if vechicle not moving as coolant temperature rises at a set point the cooling fans will turn on cool down engine.cooling fans dont turn on when you first cold stsrt vechicle unless you have AC SWITCH ON.if cooling fans dont turn on when vechicle at a long stand still or moving along slow traffic.if coolant temperature sensor been replaced and fuses and relays okay have dealership check see if pcm driver circuit working faulty pcm will cause cooling fans not to turn on.

how to change brake pads on a buick century?

how to change brake pads on a buick century?

Front brake pads are usually easy to do. Take only one side apart at a time. You will need a big C clamp along with other basic hand tools. After jacking the car up and using the proper safety stands remove the wheels. If you turn the steering wheel so you can get to the back of the brake calipers easier.  Now remove the two bolts that hold the calipers to the back of the wheel spindle and carefully take the calipers off. Remove the old pads, pay attention to what pad went where. Take the C clamp of slowly squeeze the piston the caliper in. Remove and replace the rotor at this time. Put the new pads in the calipers and replace the caliper and wheel. Make sure all bolts are tighten! Before trying to drive vehicle make sure you press the brake pedal many times. I hope this helps.

1996 Buick Century 3.1L V6 P1441 EVAP Problems.

I have a 1996 Buick century 3.1L V6 that has recently had the head and manifold gaskets replaced. About a month later the car began to shake and sputter a lot in drive. I noticed it did this mainly in the morning or when it just rained. It would only do this in drive. When I was at stop lights I had to put the car in neutral just so it wouldn't stall out on me. It has of course stalled on me numerous times. So I took it to auto zone and they told me it was a code P1441 EVAP system- No flow during purge cycle. Which i knew right away it is most likely the EGR valve or EGR valve gasket or the EGR pipe gasket. So I went ahead and took off the old gasket which was corroded and replaced it with a new one, both the egr and the pipe. It seemed to be running fine for a while. Then today I went to drive somewhere and it started to stall again. I do not know what else it could be besides a vacuum problem and I do not want to replace a ton of parts hoping thats what it is. And if I take it in they are gonna tell me its all kinds of different things and charge me up the wazoo. I could try replacing the cheaper of the parts until I really have to replace the EGR valve. But I am not sure what else it could be besides the canister or the canister solenoid. Please help me out. Thank you

I work at autozone and as the man said the evap system maybe the fault that can up on the obd 2 code reader but if no ither codes came up then you
can have a problem that is not code related ( as early car 96 to 2000 the service light only covers things that are in the pollution part of the engine..
the newer cars the service engine / malfunction light will come on for many other things
if your egr is not seating on idle then you would stall at a stop if you egr stays closed then your car would be polluting and could not pass e-check
if the car is not running properly and it has a multiport fuel injected system /coilpack system
change the cranksensor ..If you have a distributor
change the pickup coil/ ignition control module
these are both in the distributor...
as long as you have good wires & plugs you should be in good shape

P1441 Evaporative Emission (EVAP) System Flow During Non-Purge
The evap system is your egr valve, carbon canister, pcv valve, gas cap, and fuel tank vent, The most common fix for this problem is a new gas cap and then your done. It is about 15 dollars and then you pass smog. If this has been of any help please reate. Thank you

buick century 96 overheats, and ive done a lot to fix it....?

I have a 96 buick century and lately its been overheating, first thing i did was check the coolant, but even after i put it in, the reservoir would be bone dry, and then sometimes, even in the same day completely full. Finally my overheating got so bad that i took it to a mechanic because i couldnt drive more than a few miles without it steaming. i had the intake gasket replaced. that helped but it was still overheating, so next i figured id replace my thermostat, i did that and there was no difference. i checked my radiator cap and the rubber seal was torn so i replaced that, and its a lot better... but it still overheats.
When i accelerate on the highway really fast, it cools back down. but normally it just fluctuates up and down with the occasional 'in the red'. Today i couldnt get it to go back down while driving which i usually can. and i think whatever the reason is for it overheating is getting worse.
please help.

I had the same problem with my 96 buick century and it was the intake gasket. The 1990's buicks all have the same problem where the gasket fails after about 100,000 miles. The radiator fluid then starts leaking in with the oil. Check your oil and make sure it is not high. If it is high, then the intake gasket is your problem. They make a special replacement gasket now that does not have the same issue. However, I doubt I'm going to keep mine another 100,000 miles so I just put in the stock gasket. Hope this helps.
