#17 of 22 loss of speed
Jan 25, 2008 (5:49 pm)
94 buick century 2.5 liter 4 cylinder 197thousand miles. A month ago I got head gasket repair wrong gasket(redone) also idler pulley the cold weather hit and it seemed like my ignition switch was hard to turn over. Never had cold problem starts before was kind of frustrated then driving to work 70 mph 15 below zero thought there was a wind gust then noticed a drop in speed and felt like gas peddle was harder to step on.couldn't go faster just kept getting slower, check engine light came on got off freeway 1mile later, temp gauge was over half. parked no steam or water under car worked all day started car not stiff no check engine light. started driving could go no faster than 30 at stop sign tried putting in park and revving engine sounded okay no missing. and no rumble noise ,put in gear. first pressure on gas like normal more pressure a rumbling noise no faster than 25 mechanic said catalytic converter. no. computer module no. fuel filter a little dirty didn't change anything gas running rich ,checked sensors they could get to, two days later took to affiliate shop .day and a half later still baffled now we are talking about drive chain or belt the first mechanic ruled out because of fiber optics. second mechanic says belt or chain 500.00 for this job just to find out yes or no. already 500. into labor of guessing .Is the head gasket responsible for this or does anyone have any ideas. do i just get a different used car.

#20 of 22 Fuel Leak
Jan 31, 2009 (12:35 am)
I have a 2005 Buick century and I can't turn on the vent because I have a fuel leak under the hood. Inside the car smells like gas. I was wondering if anyone could tell me how I can get it fixed,or if there's somthing that I can use to stop the leak???

Just had the same problem with the same car. If Im right, the smell will go away for the most part during constant drive time. When you crank up, the smell is strongest and seems to last for about 5-15 min before getting better. ANSWER- The diaphram in the "Fuel Pressure Regulator" is failing which will also cause the car to have a long start. The regulator is vacuum controlled and if i remember right, has to sustain pressure from 5-7psi. Not much. To be certain that its the problem, pull the little vac hose off of the top and smell the regulator hole. Smells like gas, its bad. Albiet, the gas will leak around the edges of the regulator. Its located on top of the engine, attached in between the fuel line and fuel injector rail. Hard to miss and not all that tough to change.
#22 of 22 PCV valve replacement
Mar 20, 2011 (4:24 am)
2005 Century, 4-cyl. My son went to replace the fuel filter and PCV valve; fuel filter went fine.
He could not do the valve because he said it is riveted in; is there a trick to changing it?
