Won't shift out of park

I have just the #3 cylinder that is low. The other cylinders are 90 dry and 125 wet. I suspect a burnt out valve and wonder if I can just pull the one head.

Seems like it's in security mode

GM wants $681 for this piece of plastic no junk yards have I read on your web site that a woman found a cover for each side on ebay but no details were given

Car is still sputtering. Recently found a crack in the valve cover which is made of plastic. Tried to patch it. Did a smoke test but didn't see a leak anywhere. What could this be? Still no warning or engine light

I changed the spark plugs a few weeks ago along with the fuel injector sensor because the gas cap warning came on/engine light. There's no engine light or warning now but my car sputters horribly in idle and reverse please help!

No problems until husband changed heater filter, starts like a dream, then shuts down.

When I turn the key back there is absolutely no power of any sort.

My mech said ECM might need replacing car runs fine but I feel it just needs Trans Fill up.

My air in dash vents does not blow out air. Only on the floor but I can hear air blowing from the dash but can't feel any air coming from vents? How can I check without it costing me a arm and leg?

My front left wheel speed sensor wire connector is damaged and is unplugged for now.Now my abs and traction control is ON.Does anyone know how much itime is to get fixed.

It starts to hum after the first 5 minutes of driving, at low rpms. It's a deep hum. I've resurched online and people say it could be the rear differential. Please help! Thank you

Traction engaged comes up on my screen service brake assist and abs is light up what do I need to do it is not wanting to go

I changed the brake light switch, bulbs, fuses and the brake light connectors. after changing all the it is still burning the fuses out. there is something in the wiring that causing it to burn out the fuses. I need some advice on what to do next
