Here's the deal, when I go to give my car about half throttle it bogs down and instantly goes into limp mode. Not sure what the problem it but it just randomly started lastnight on my way home. The car also will hold rev's in between shifts and idle sporadically.

Here are the codes she threw:

P0121 Throttle Position (TP) Sensor 1 Performance -PCM
P0140 HO2S Circuit Insufficient Activity Sensor 2 -PCM
P0141 HO2S Heater Performance Sensor 2 -PCM
P0068 Throttle Body Airflow Performance -PCM
P0069 Supercharger Inlet Pressure (SCIP) - Barometric (BARO) Pressure Correlation -PCM

Any help will be appreciated.

Nobody?

Someone knows.....and they're proably the ones that are still asleep lol hope you get an answer cause I wouldnt be much help as far as diagnostics

Rangerondubz

Yeah I know its still early, forgot about that.

Sounds like O2 sensors and catalytic converter issues.

After more testing it seems not to bog but when I give it gas it takes off then jerks the car b/c it goes into limp mode.

This blows

when u get the codes checked / eraced they should be able to tell you what could caust alll of them to fail like that. ( i had this problem but not as many codes... mine was a cloged cat. ) which inturn the cat could be cloged and not leting the rest of the intake or inlet side of the motor breath.

I had the throttle position sensor code when the connector that goes into the throttle body got disconnected
And it also put the car into limp mode.
That could be part of it
Idk about the rest of the codes though

oh oh i can maybe help lol!

my car did this before. i turned the car off for about 5 minutes then turned it back on and it was fine.... i took it to the dealer and they said it was the Throttle body but it seemed fine now.... so after it did it again we found out that after boosting hard and letting off the gas to fast it jammed the TB shut and it got stuck for a sec causing the car to panic and go to limp mod

and judging by your codes its the same

Rangerondubz

But here is the thing, I clear the codes w/ my interceptor then I can give it gas and it will do the same thing again. Also runs like total ass w/ in Limp

I think it may be the Throttle body, it will only do it if I give it half to full throttle at any RPM. Also it will hold revs during a shift or when I am in neutral so im thinking that it may just be dirty.

Still open to opinions though.

Let me get some responses people

Jackalope

A bad TPS alone may cause all of those codes by the PCM not knowing where the throttle actualy is. When did it start? Did you do anything to make it happen or did it just crap out?

red_line_cobalt

your TB could be jammed...... that was part of my problem, the only reason it just went away was because it freed its self up but if it didnt it would have kept running like yours. take your TB off and look and see if there are marks from the valve getting jammed

Rangerondubz

Got it fixed! Yes Redline there were marks from it getting jammed. But I took the intake coupler off and shot a few sprays of TB cleaner and move the butterfly alittle myself, then put the coupler back on a voula. Thanks for the tips Redline they helped me out.

Thanks all.

P0068 should be set to 8000rpm. disable that ****, its useless. the '07 stg2 tunes actually have this set to 8000 from the factory.

Rangerondubz

Will do. Anything else?

anthonyS88

I don't know, ben tryig to get my refund since may, haven't been able to contact him since October. Just want a response from him
