Question about 1995 GMC Yukon

1 Answer

My 1995 yukon stalls and has a rough idle

My yukon will stall when I stop at a red light. Not at first, but when I give it some gas. It also wants to stall when merging on to the interstate. It usually only does it for the first 5 or 10 minutes of driving, after that it doesn't happen. It almost seems like it's out of gas, but it isn't. Also, when I am driving at a higher rate of speed it doesn't happen, I think because it's under more pressure. I have changed the spark plugs, rotor, distributor cap, and wires. I have also replaced the fuel filter and ran some gas treatment through it. Nothing seems to work, and mechanic shops want to try this and that without actually fixing the problem. Any help would be greatly appreciated.

Stalling at low idle


I don't know this specific car. But, if it has one, check your Idle Air Valve. This can cause the engine to stall. If you can hold the gas pedal and the engine will continue to run until you let off the gas, it is likely the IAV. It will not necessarily cause the engine to run rough. That could be a number of things like spark plugs, wires or dirty injectors. It could also be a compression problem. Is the check engine light on?

My 2007 Chevy Silverado loses power when I come to a complete stop no engine lights appear but if I turn off the truck the problem goes away for awhile .


Loss of power, but no mention of rough or inability to idle (including stalling). If those additional symptoms are part of the problem, check for a vacuum leak to the intake. Listen for hissing or sucking noises near air hoses. Look for loose, cracked, or broken air hose connections. Check PCV valve...Cheap to replace, could be sticking, then loosen after truck sitting with engine off. A vacuum leak will not give any light indications, and vehicle will seem to run normal when applying gas, but will want to stall or run rough (or want to stall) when at idle or sometimes when taking foot off gas when slowing down.

Stalls after getting gas then starts fine. Also noticed it idles rough at other times. No trouble codes. Any thoughts?


When it stalls after getting gas, are you filling the tank up beyond the first stop? I was filling mine up after the pump shuts itself off in order to top it off as much as possible. I learned this can plug some type of purge vent or something like that. I stopped topping it off and haven't had a problem since. Mine would hesitate and then die at the first couple stop lights after getting gas. From what I've read, the cheap fix is not to fill it up past the stop point, but the permanent fix is to replace the gas tank since the vent physically part of the tank.
