Question about 1995 GMC Yukon

1 Answer

Running rough - hesitant

95 Yukon 2 door. 300,000 kms - so engine is a bit tired. vibrations while accelerating - really bad when going up a fairly steep hill starting at the bottom with a low speed. RPMs seem to stall for a split second and it feels like there may be a problem with the exhaust, but I've heard it could be a distributor problem. Taken it in twice, and mechanic can't seem to find it. otherwise running sound.

    haven't done any towing since the problem started a month or so ago. it's just the vibrations that seem to come and go, and tend to be the worst when going through hard acceleration on an incline. The vibrations are also pretty bad when the gas is on lightly. I just noticed today that while going up a hill, when it seems to hesitate, that the RPM needle drops a bit, but only for a split second. water in the gas could be an idea, as it's as if it's not getting a clean intake of fuel.

    first thing i would suggest is to buy a couple bottles of gas line antifreeze and add them to your tank... (it sucks up any water in your fuel)... what i am wondering... does it make any odd noises during hard acceleration/loads ?

You may also want to consider that the coil pack is failing... i remember when my windstar coilpack failed i had an awful time just getting up a small hill... can't recall if it shuddered tho.

I have a 99 ford f150. Sometimes it runs perfect, then out of no where when I try to accelerate it vibrates bad and becomea hesitant. When I came to a stop I switched threw all gears and it seems like it...

This sounds like you might have a bad plug wire or something else in the ignition system is arcing to ground. A quick way to verify this is to run the truck in Park at idle. Next, spray the ignition wires with Windex. You'll notice the truck starting to rough up and might even see the bad wire arcing to ground. A complete tuneup would be recommended in this case.
I hope this helps! :)

My f-250 99 v 10th sputters when I accelerate sometimes stalls why?

it could be just about anything. first start by checking plugs, wires, and coil.Engine hesitation, which is normally most apparent during acceleration, is a condition that often results from either abnormal fuel flow to an engine or abnormal electrical conduction to a vehicle's spark plugs. Bad spark plug wires, whether they degrade internally or develop cracks and breaks in their outer coverings that cause electrical interference, can cause an engine to hesitate. Engine Surging, Engine surging is a common symptom of bad spark plug wires, especially if the wires have cracks or breaks in their outside insulation, heres the symtoms for a bad fuel filter. Engine Hesitation, Engine Stalling, Rough Engine Idle, Reduced Engine Power. if really plugged it will stop fuel flow and car will not start. just give it a good tuneup, and go from there! good-day!

My 96 jetta is really loud and vibrates bad

The cam shaft sensor operates the speed and spark of the engine without it work properly the car will shake and will not run good. It will run rough and will hesitate and may even cause more damage if continued to operate in this state. Cam sensors are not expensive anyhow anywher from $50 to $150 good luck

Should i buy 97 sentra with 365,000 kms?

That is a wide open question with many variables. If the car is cheap and you need transportation quickly, maybe. That is a lot of kms for a '97.

If the car has a good maintenance record, again, maybe.

Personally, I would not buy a vehicle with over 300,000 kms. unless I really needed something right now.

You could take it to a mechanic and have them check it out for you to see if there are any obvious problems. That may mean spending a little money, but may save you in the long run. Good luck.

Thanks for using Fixya.

Hesitates on acceleration

Does the car always hesitate during acceleration? If it ALWAYS struggles when it starts or ALWAYS hesitates on acceleration then I would say the issue is fuel delivery. If the problems are more intermittent and come-and-go then it could be an electrical issue.

I would start by changing the fuel filter. Changing plugs, wires, cap, and rotor are all good things to do as your budget will allow. I doubt you will have to change your injectors.

If you end up replacing any rubber fuel line, be sure to use the high-pressure stuff made for use on fuel injected cars.

I hope this helps! -Nick

Check the timing and compression of the engine. It sounds like you either have a blown head gasket or a the timing jumped.
