Reply With Quotetry to change the rear oxygen sensor because mine does the same but when i unplugged the rear oxygen is does do that but when i do i does
So since I got my 7G i had this problem , when I drive normally I its all good but when I floor it cars chokes/shakes rmp is between 2 or 3 and it doesn't accelerate. If I i press gas gradually it goes up to red line but if I floor it i chokes and control light goes up its says its misfire , 1)Cables 2)Spark plugs 3)Fuel Filter 4)Injectors 1 year passed and I did all tune up parts plus fuel filter and checked injectors and still the car chokes when I floor it. Today i was talking to my friend who is a mechanic he said it looks like its Mass flow sensor or Mass flow adapter. He also told me to change air filter. I'm thinking about putting Short Ram Intake , I would also change that flow sensor and flow adapter but are those parts expensive? and also do you think it might be it? and third what are those things really doing? Maybe little lesson would be nice ;) Thanks!

front o2 sensor is what you need replaced. the rear o2 sensor does not affect the fuel trims at all. its there to tell the ECu that he catl. converter is working
ok
I'll record video how the car reacts when I floor it tmrw
Mko how many times do i have to tell you this!!! When my rear o2 sensor was not it my car ran like that!!!!! LOL It could be either of the o2 sensors.. I would also say that you injectors could be clogged...
Replace your MAF with a known working MAF...I believe this will solve your issue.

no guy i just know is the rear o2 sensor because i take off mine and it dont do that no more
im posting video right now so you can see how it looks in this case...
Please take your time with typing... I cant understand anything that you say...
also, check your timing. could also be the mas
X2
It chokes ever since I got it but I did timing belt and all componets with it and its still chokes so its not timing , Here is video : http://www.youtube.com/watch?v=j1RQxrCbOq4also, check your timing. could also be the mas
Put volume up so you can hear it good.
hmmmm, that is wierd. did you check compression?
i going to tell one more time i got the same problem ok when i disconected the rear o2 sensor that didnt happen anymore
That means that your O2 sensor is bad!!!! Change it.. Just becasue it sounds similar to your problem does not mean its the same exact problem!!!!! It could be a bunch of different things!!!!
How do I check O2 sensors?? just disconnect and floor gas without them or what?

guys any ideas?
yeah disconeted that it
Yea dissconnect the back o2 sensor and then drive.. If it runs even worse or a new problem come about then its not the problem. But if you take it out and nothing changes then its time to replace it.. Also you can try the front o2 sensor...
