well i got a 06 ss sc. all stock. but got some things going on with it. 2 weeks ago the car ran fine. and was great. then parked till today. Today i went to drive it around a little. Well im only pushing 4 lbs of boost acording to the gauge. And im barly cherping the tires in 1st gear! its slow, really slow! But the motor is running like a charm, no smoke, no werid motor sweeks or noices. Like i said last 2 weeks it was running great!, 10-12 lbs of boost, ran great. I have noticed one thing though. when i rev it up, and when i hang around the rev limiter (stock at 6,500 rpms) for about 1/2 a sec to 1 1/2, then it'll die? then starts up just fine right after (all revs are done once the car is warmed up, no civic owner here LOL ) ? i did have a check engine light, but i cleared it with taking the battery cable off, cause i cleaned my maf senor today. So what could be the problem? Im dumbfounded. The car runs fine, drives fine, mine doesnt even jump in the rpms like most lsj's cause i cleaned the TB. , but is boosting really low, and is super slow. I hope its a simple fix. cause this weekend i wanna put my header and downpipe on . lol but any help would be great!

 

Did you happen to check what the engine light was before resetting it?

 

i had it for a long time know, and my uncle went to check it out and it read the maf sensor. so its finally sunny in washington, so i decided to clean it, and unhook the battery, then hooked everything back up. and went for a drive and it did the same thing.

 

wierd... no suggestions here man i wouldn't beat on her until its solved tho, seems like the engine is pulling timing or something

 

its not getting driven till i figure out the issue. I just did 2 pulls last night, and it felt just a little faster than my aunts stock base saturn ion.

 

you know anyone with hpt? maybe you should datalog and see what your afr and stuff is doing

 

no i dont. Im gonna wait for the check engine light to come back on, and go check the stupid thing.

 

Supercharge bypass valve stuck open?

 

might be a stupid queistion, but where is it located?

 

bottom of the supercharger, its like a throttle body that closes as the actually throttle body opens. and you know what thats actually a good idea, insylem i hadn't thought that far. because really boost can be dictacted on whether that is opened or closed. when its open your in vacuum, closed ur in boost (air only moving through s/c rotors instead of through bypass)

 

0:38 in you can see how it works

 

sounds like TB problems (once it goes bad, no matter how much you cleanned it wont work).

 

the car has 3k miles. so unless it went bad from it sitting. but theres somthing weird. the car will go up to rev limiter just fine but slowly, at 4lbs of boost.

 

only 3k original miles? damn!

 

yup, i think the lowest lsj out there. Only problem are my factory tires are starting to weather crack, but im gonna run them down till they blow . lol

 

haha wow! definately atleast ONE of the lowest out there. i do remember seeing a red 05 lsj on ebay once with i THINK either 15 or 150 miles on it. sorry to burst your bubble i'll hope for your sake that someone bought it and put a few K on it since then though lol

 

haha thats why i said I THINK also in the other post. and thats damn low! lol when i first got the car, it had 620, after we fixed it, we started driving it around a little though. then relized my bellhousing in my tranny has a crack, so i stoped, execpt for bringing it up and down the road a couple times a month.

 

if anyone had a simaler or the same problem with there car, please let me know what fixed it.

 

Even if the TB is bad, it should still be able to hit the rev limit with no boost.

 

Id replace bypass valve

 

yea i guess u could start by taking off ur s/c and seeing how the movement is on that valve idk how you would replace it tho

 

The black module on top of m62

 

Take it off an check the movement for it, it may not be working correctly. If you need to get a replacement call ZZP they can get you a new one. Call, and leave them a meassage and leave your number they will call you back. Def sounds like the actuator isn't working properly..

 

would this fix it? how much are they new. And thanks guys, but im gonna replace the stuff thats in the way first, when i replace my tranny, if the other stuff dont work, then ill take the supercharger off and see what its doing.

 

Have you looked at all of your vacuum lines? I would check those before replacing the bypass. It's possible you have a leak. That or a s,all rodent creeped into your intake and is reducing your airflow pre-maf
