Default big problems with my daily please help quick!!!!

my car feels like it is missing at idle it drops to like 500 from the stock 800 idle. then while your driving if you are barely on the gas like crusining it starts to feel like it is bogging as well but when you got wot or give it more gas it clears up and runs fine but when you let off again it will start to bog in the same condition. could this be a fuel filter issue car is a 6spd and has 110k on it. idk if it has been replaced. it throws no codes when this happens check engine light stays off.

Had the same issue about a month ago and it was a bad spark plug and wire. My advise is to get it scanned.

CODES!!!! See if it has any stored codes or anything. Sometimes the damn check engine light will come on and go back off before you know it...at least mine has several times. Good luck bud

Find a legit shop and have it hooked up to a machine..not some snap on deal. And to be honest I'm no tech so couldn't tell ya what to look for. Sorry.

The Tech 2 GM tool is the best but Snap-on's will pull codes just fine.

I agree with elliots94z, the same thing was happening to me about a week after I bought the car, and I got under the car and looked at wires and one was hanging off of the opti. So look under and make sure nothing is off that shouldn't be and let us know what you find out.

Ya man, now would be the best time to see if there is a wire problem, just look for an arch somewhere and see if you need new wires or if it is something else. My car was arching on the coil right behind the waterpump near the smog pump.

That sounds like a good way to fix it, expensive, but permanant. Well whatever it is man i sure hope you get it fixed since its your dd. Good luck.
