I have a reader on this thing and I was wondering if my readings are correct
Absolute tps 16.5
Calc load 15.3
Maf .31
Map 10.0
Ign adv 10.5
Lt ftrm1 19.5
St ftrm 10.9
02s11 (v) .290
St ftrm11 (%) 18.8
02s¹²(v) .055
It keeps going into limp mode after driving it a bit when you really build boost but if you drive it normal it's fine
I've cleaned the maf map and changed tps and the one on top the super charger idk what's going on it just goes into limp mode and if you shut it off for 60 seconds it starts right back up and runs ok

It threw the p0068 code also

 

those fuel trims are fairly far off, look for a vacuum leak maybe

 

ok other than the vacuum lines running on top the motor what other lines could it be? I believe im going to run all new lines up top because i thought that may have been a problem

 

I bet you need a throttle body.

 

The actual procedure lists a couple other things but redirects to a code directory and being as how youre not setting any other codes and the age of that throttle body, i bet that will do the trick

Edit: When you say youve changed tps, did you actually replace the throttle body? If not, try watching your tps on your scanner while you slowly press the gas pedal with the key on and engine off. A lot of times when they go bad, there will be a dead spot on them that when you get to it the throttle blade will go bananas and start fluttering trying to find where its at.

 

yes i did change the whole tb...the one i changed to wasnt brand new but i wouldnt think both of them would be bad
and it did throw P0502 and P1182 and P017pd when i first cleared the codes and after that it was only P0068 a

 

Map is 10kpa? Do you have gms1 sensors? Check the wiring for the map sensors. If it drives fine just doesnt like to boost its likely not the throttle body.

 

yeah it drives fine if driven easy but when you start to pull hard it will throw it in limp mode and if you shut it off for 60 seconds start it back up itll be fine until you boost hard again. i drove it 30 min to work today without a problem i just didnt drive it hard

how do you know if you have gms1 sensors? lol im a newb when it comes to these haha

 

nvm, i was thinking you had a turbo car. i would still check the map sensor wiring and maybe test the map sensor.

 

how can you test the map sensor?

 

back probe it with t pins and test the voltage with a multimeter. i can get you the connector view and the normal values

 

yeah that would be awesome i appreciate it

 

can you look at MAP voltage with your scanner? check it at idle. What does your vac gauge read at idle as well?

 

also check for intake leaks since your fuel trims are so hgih

 

yeah the map read 10.0 at an idle and yeah my gauge does read vacuum at an idle it reads around 15-17 pounds of vacuum. and i will check for more leaks tonight

 

I take that back it sits at 19 and the coupler was cracked at the TB I put a bigger clamp on it and it runs just fine!! Thanks guys!

 

I would also check your evap purge valve solenoid to make sure it holds vacuum. When they go bad the car acts just like it has a bad vacuum leak that you won't find with a smoke test and can throw all sorts of codes.
