Car starts and idles great but has no acceleration unless you punch and than takes off. Replaced in line fuel filter, plugs, and cleaned E G R valve no change. Service Light flashed but still does not stay.on. when First start in morning runs the way. It should very briefly

It switch out no problem

when you floor it it takes off. will not accelerate when slowly pushing on gas pedal. no engine light on but has flashed a couple times

Checked fuses and everything

It will start if you don't go all the way to the ignition switch stop.

I suspect there is a problem with the switch.
What do you think

When driving all the time. When vehicle is stopped, it stops too. Definitely not the brakes. No shaking, just a humming singing type of sound.

We keep putting batteries into this car and after few months its dead. We have gotten 4 batteries within months. We have a rebuilt alternator that i think is the problem because this our 2nd time getting it rebuilt. Can the alternator be the issue? Starter checks fine. How can i check for a parasitic drain also?

02 Buick century and damn battery keeps draining. First time it was alternator. So we got it rebuilt with lifertime warranty. Second time it drained it was the alternators diode's that were bad. Now this time I believe its the stupid rebuilt alternator. Starter is fine. Might as well buy new alternator!!!!

It's a v6 and should pick up like it use to. There is no misfire. It just doesn't want to pick up like it should. It also does it on flat ground. Please help. Thank you.

I have an intake gasket leaking coolant in the back of my 2002 Century Buick engine.
The shop told me it shorted out my starter. If I replace the starter will
this happen again in a short amount of time?

The blower works and operates fine, but the temperature of the air doesn't stay hot. It works sometimes for a few seconds at a time, other times for a few minutes. In the morning when it is colder out it doesn't work and my low oil light comes on. In the afternoons when the temperature is around 50 it works no problem and the low oil light goes away. I recently learned I need to replace the inner manifold gasket due to a small leak, but the shop estimated it would be months before it needs to be done.

Have been told its the head gasket - sound correct? 70,000 miles

Have been told its the head gasket - does this sound correct?
