Question about 2000 GMC Yukon

1 Answer

Engine misses while at idle and at city speeds I can feel a miss every now and then, especially at stop lights. It does it in park as well so I ruled out transmission, I'm a little spooked it may be fuel pump. Put some injector clearner in the tank and through 3/4 of it and it hasn't helped. What could it be?

My tractor loads up at idle bad how do I repair


if its a gas powered engine , id be looking at the low speed /idle jets in carb , also can be a miss matched float /bowl arrangement in carb (if parts were ever changed) , a super dose of auto grade fuel system cleaner sometimes saves a ton repairing and rebuilding on these , especially on infrequent used engines that sit for long times

My check engine light blinks for my mercury cougar at idle at every stop light, stop sign, everything as soon as i stop or put it in park it starts blinking whats wrong?


Usually when your check engine like is blinking it means you have a miss fire. You can go to Auto Zone and have them pull the codes and it will tell you what cylinder is misfiring. ( if you want to only fix that one miss).

1991 Chevy Caprice has a mild miss fire and stall at low rpm: This is my latest update: I checked and cleaned the EGR,PCV,IAC valve, M.A.P sensor and Throttle body(bore/butterfly). with carb cleaner....


Do you have the idle speed turned up to keep it from dying? Because it is high. Check engine light on? Have you checked for vacuum leaks at the gasket under the throttle body? How does the car run under acceleration? You might have a worn distributor shaft.

missing at idle and good at highway speeds typically means either leaking injectors, vacuum leak and/or base engine concerns

I'd start with the injectors

1999 Lincoln Continental 4.6 32v engine...idles smooth in park & in gear. In park I get a engine miss when revved to 4000rpm. Also seem/feels like I have a miss at lower engine speed when being driven....


hello, i first must ask why that engine would EVER be reved to 4000 RPM? it is likely you are up against the rev-limiter and your ignition is made not to over rev. be very careful....4000 RPM on that engine could/will severly damage your tourque convertor........very expensive it is common for the EGR passages on that model to plug up with carbon, remove valve, clean ports, and retest for low speed miss/hesitation, good luck....marty

3.4L engine stall at stops


do u have a check engine light coming on? if not the plugs are not the problem a miss will trigger a check engine/service engine soon light, most likely you have a dirty automatic idle speed control motor.
