Question about 1991 Cadillac Seville

1 Answer

Car bogs down when given gas.

Car bogs down.... Any ideas? Driving down the road at 65, cruise engaged i start to slow down, but the pedal starts to go all the way to the floor. What would cause that? the car itself didn't die, it just wouldn't allow the speed to increase? 96 Cadillac Seville STS automatic. Thanks in advance.

Hi there,
This problem is most commonly caused by a weak fuel pump. It will need to be checked with a fuel pressure guage. If you can obtain a fuel pressure guage you will need to observe the fuel pressure while accellerating to see if it drops out.
good luck

2003 oldsmobile alero v6 -- cruise control stopped working...The cruise on/of button lights up, the green light cruise indicator comes on in the dash panel, but cruise control does not engage when CST SET...


Try checking the small switch at the top of the brake pedal. There may be two one for brake lights and one for the cruise control. To ascertain what is what, pull one wire off and see if brake lights work. If not, then the other switch controls the cruise control disconnect and engage..I you have a DC test light check to see if power is on on both side of the switch with brake pedal up. If so, depress pedal and check power on the other side there should be none, if there is the switch is defective.

When driving my 99 cougar and shifting into neutral at a stop sign/stop light my car remains at high idle and grinds teeth when I put it back in first. What could be the problem?


Sounds like the gearbox. But the test is this: Engage 1st and start slowly releasing the clutch pedal DONT HIT THE GAS. The engine should gradually fade out and bog down when the pedal is completely released. If the engine just bogs down at some point, or the fading is not gradual, the clutch is damaged. If you hear grinding its the gearbox.

Car randomly accelerates without pushing down on pedal and cruise control is not working


It sounds to me like a problem with cruise control? Turn it off and/or unhook it, drive it a bit and see if accelerating problem goes away? If it does, you need to troubleshoot the cruise control. Any applicable trouble codes?
That sounds dangerous to me, I'd disable the cruise control till you find the problem.
I don't know what testing you have done?

My car keeps stopping as I'm driving, could this be the Cadalic Converter


Most of the time when your converter starts to get clogged up when you push the gas pedal your engine will "Bog' like it has no power. if you are just cruising down the road at it is cutting off I think you may be looking at another problem. Most likely electrical but don't quote me on that but that is where I would start. Good luck

The auto gas pedal stopped working and had it fixed and since then the cruise control will not engage. 2001 Lincoln town car. appreciate any help.


sounds like a switch not working right in the cruise control take it back to the guy who "fixed it" and get him to "fix it" right this time,, its likley to be the brake switch sticking on, this wont let the auto cruise control engage, it keeps thinking you are trying to brake to slow down so it kicks its self out just as it should if you were driving in auto cruise you then need to reset it to go back into auto cruise

Bogs down on acceleration


buy 2 fuel filters. buy can of SEAFOAM at parts store. use 1 f filter to replace old one(you'll probably see old looking gas, with an odor).Pour SEAFOAM into tank. fill up with PREMIUM gas. after about 100 miles change out fuel filter 1 last time..add SEAFOAM every 3-5000 miles and you should be fine. the ethanol in the gas turns to goop and adds water to your fuel, and puts carbon on your valves and through out your emission and fuel system. The ethanol will be alright as long as you follow these instructions. and the SEAFOAM will keep you from having line freeze up in the cold months ahead, and will give you better gas mileage. good luck.
