New car to us today, checked lights after dark to see if they all worked,shut car off,little red light on top of dash started blinking.What is this and won't it kill the battery ?

When I pick up speeds to 80 mph and make a full complete stop it takes off fine but if I don't get it up to 75 or 80 mph first it will pull off and pick up speeds very slow what is the problem?

We had a tune up done and it still say cylinder 4 is misfiring what could this be is the engine going bad or is it something easy to fix . And the car is stalling and then the engine light blinks.

When using repairpal for an estimate it doesn't the whole assembly, just fuel pump.

Fuses are good. It use to work sometimes but now nothing. Please help. Need heat for my mother and kids.

im reading something about a Pat System before I could install the new pump my car got broken into my whole colum was destroyed so I had to switch out the old colum from another drand marquis it even came with the pat key hoping for the best when I installed the new colum the car still wont start it cranks like it wants to start but doesn't what do I do im being told I need a diagnostic scanner with pats cability to reprogram the anti-theft security
