If you want help with car repair without being a ****head... Then yeah we can do that... Otherwise, go find a mechanic who knows nothing about your car and ask him and kindly leave us alone. Caps lock is really annoying and pisses people off.... Simple right?

if the vacuums are alright and the coil packs too check your injectors they might be plugged or broken do an injector test....

 

Noz has a good point. But your computer would have a bank reading lean if it was injectors.

 

Which cylinders are misfiring? You said one, but did not name anymore.

 

The first time Hooked the tech II it was showing the #5 cyl. I drove it 4 a couple of days with the hard on pedal stumbel than checked it again and it was bouncing around all cyl but 1 and three was the worst. I changed the fuel filter but still it stumbles. Today I unhooked the MAF and still it stumbled.The next thing I think to do is have the injectors flushed. Then maybe O2 sensors. I guess????

 

If you unhooked the MAF and the car is still misfiring it's not a problem with the O2 sensors since they have to input to the fuel mixture when the MAF is not plugged in.

 

Do they not make slight adjustments for the MAF as well? Which would mean they are an input anytime in closed loop.
