Car wont accelerate when going up hills and sometimes when depressing accelerator the car wont respond,its sluggish,Any ideas on what is causing this sluggishness?

I think I would check the fuel pressure and the maximum fuel pressure from the pump.
I would look to data if temp sensor , map, tps,
lack of power can be cause by many things
hope it helps

Clean the throttle body and maf or map sensor.

There's many reasons this can happen, but start simple. Fuel pump may be failing. Usually under load they can not supply the fuel the engine is demanding. (Up hill acceleration is a classic example). change the fuel filter first, if that doesn't not correct the problem, test fuel system pressure. (:

This happened to my 2003 Trailblazer at about 70,000 miles. Going uphill it would slow down and then downshift as it dramatically lost power. Bottom line, the Catalytic Converter was plugged. When first accelerating it ran fine but after that it acted up and got continually worse. You didn't mention if the service engine light came on or not. Something else that might cause the no power is the fuel filter may be plugged. Change it first as it is cheap compared to the converter. Good luck.

possible mass air flow senser

No as long as the engine was running the turning of the steering wheel wont hurt it and dont let them tell you otherwise,,as for all the other problems you have
TELL them that if they dont fix it problems ans a lot of them You will take it to the TV and let them tell 10000000 on air they will change there minds.

Let me know how you get on Ron

Hello there, First I would like to mention that turning your wheel had absoulutly nothing to do with the problems you are experiencing don't beat your self up over it. To me it sure does sound like you have some thing going on. You might want to take it to a reptutable reapir shop that you can trust to get a second opinion, not pointing fingers but sometimes warranty work is not the favorite thing some dealerships like to do.

I think you do need to address this before something may happen because the noises and symptoms you are describing are not normal.

Good luck and I hope this helps. Allen

check the fuel filter and when was the last time you had a tranny service done and a tune up also check the drivebelt

I THINK THEY MAY HAVE DAMAGED THE PLUG WIRE BOOTS, TAKE A LOOK AT THEM AND SEE IF THE RUBBER BOOTS ARE TORN OR DAMAGED, CHEAP TUNE-UP SHOPS ARE FAMOUS FOR CAUSING THIS KIND OF DAMAGE, THERE IS A SPECIAL TOOL TO REMOVE THE WIRES WHICH GET STUCK TO THE PLUGS, MANY YOUNG KIDS DO THE WORK BUT DON'T EVEN KNOW THE TOOL EXISTS.

hi what is your car have no codes come up if not do a fault reading see if it has stored any as tps [throttle position sensor ] map sensors and airflow sensors will cause this problem as will a few others it can be expensive guessing yates210456
