1 Answer

The problem- i was told the car is in safety mod, anytime i get around 4,000 rpms it feels like im topping the car out it kinda jumps, it feels like it struggling my check engine light went on for a few hours , but now it's off i went to advanced auto and they put a diagnostic reader to it and the first time my car said it wasn't throwing any codes, i went back the next day and then it said , emissions so im thinking something might be loose ------------------ my extended warrenty just ended too -a buddy of my mine said it might be due to a dirty 02 sensor has anyone ever had this problem i have about 77,000 miles on my car

It can be a 02 sensor. it can be spark plugs or even the spark plug cables.
it also can be oil level. check oil level in the transmission oil, if you have to much, it can also creates this problem.
you can also spray some sea foam deep creek thru the vaccumm lines or the air intake to clean the bodies.

Sound like she's idling too low.You're going to have to adjust that.You might want to check the spark plugs and plug wires...sometimes the plug wires can slip off and it feels like you went down a few cylinders.If it feels like it's going to cut out on you put her in neutral,that will take the strain off of the motor and what not.You should go to Auto Zone and get them to hook up to the car's computer to see what's wrong.Auto ZONE does it for free.Or if you have a mechanic friend that have a diagnostic meter, he/she will hook it up to car's computer also and it will tell you what codes are coming up and the mechanic can tell you what they mean and how to correct them.GOOD LUCK!

Car cuts out rpms jump around feels like out of gas then dies?


Wow, you've thrown a lot into your paragraph (rpms, going up hills, chugs, dies, when it warms up, when the A/C has been on, etc). With that said, I'll try to help you with what i know and what you said, and provide you with supporting diagnostic articles.

For the engine's cutting in rpms, incremental loss of power, see this handy diagnostic article that provides you with a list and explanation of the most probable causes:
http://yourhandymanzone.com/Your_Handyman_Zone_How_To_Pages_Vehicle_Car_Zone_Cars_Trucks_Vans_Engine_System_Engine_Power_Less_Than_Expected_Normal.htm

When the car dies when it is warm and the A/C has been on, review these articles that specifically address such circumstances:
