ok guys i installed my nwp spacers on my 02 max and i did the block off plate while i was at it. after i got done i did the the the throttle relearn procedures, started the car and the car runs real rough for about three seconds and then it dies. i tried giving it gas and it acts like it don't won't to take the gas and then it revs real high. also as i try to give it gas it gives of a small backfire through the air box. i cleaned the throttle body too if that may help with anything. i didn't spray it with anything just took a rag and wiped it out. i double checked to make sure everything was hooked up. what could possibly be wrong?

Its leaking somewhere feel around the gaskets . also what kind of rvt did you use on the seal for the intake manifold part

dnice02

It's gone be hard to feel form a leak when it wont stay running long enough for me to get out of the car and get under the hood. i used the red high temp silicone.

Hmm. make sure the maf is connected, and re do the learning procedure. If that does not work I would disassemble and make sure everything is sealed properly again. something is not sealed correctly.

maxima dude

^^ this and see if its on the right way...also try to take some extra sealant and go around all the spacers on the manifold

I had the same problem last week when i did mine, the MAF sensor was dirty.

If that's not the problem, like everybody said, check around for leaks and make sure the TB spacer is not backwards or upside down.

did you manually move the throttle plate? Also, make sure all the vacuum lines are connected, if there is a big one unplugged it will do exactly this

and you would def hear it.

yes i manually moved the throttle blade. hope i didn't f**k nothing up.

Gremer is going to have to chime in, as the only experience i have is that the gears are fragile inside of them. but Im sure everything is okay. I would try the relearn procedure again man.

Is there a right and a wrong way to put the TB spacer on?

perkman87

iTrader: (6)

its pretty obvious, as long as the ports match the spacer you are good.

o ****, that might be costly. you cant manually move the butterfly in the E-TB, you can totally screw stuff up. Some people have had to replace the TB and ECU to get it back to normal. Others only need to do an idle air relearn, others it works out just fine. I swear this issue comes up at least once a month, im not sure how the threads always get lost or why it seems like very few people actually know that it can really be a poor choice to move the butterfly yourself

the weird part Is i never even had to do a relearn procedure

Same **** happened to me car turn off once but turned it back on and kept giving it gas the car sounded like **** but stayed on tried that procedure like 5 times didn't work went driving a little bit and the idle went a little smoother bvut still rough and then the next day was still there but minor the 2nd day completely gone think the idle is getting used to the new flow and a couple of more days past and the CEL went off by itself. So dont panic everything should be cool just got to give it a little time I was pm'ing everybody about it when it happened to me but good luck!!

definitely do the IAV relearn to begin with

5 ltr. beater

it sounds like he has a major major leak. i doubt he f'ed anything up.

OP do you hear a loud hissing noise from around the manifold as the car is dying?

dnice02

iTrader: (1)

5ltr the car wont stay running long enough for me to check for any leaks. it's kind of hard to do this by yourself. what kind of rtv did you guys use?

Crusher103

iTrader: (10)

Vacuum leak.

u have a vac leak somewhere, take everything off and do it again. make sure everything is torqued down and all hose connected. Just one vac hose left unconnected and the car will start but not run.

Crusher103

iTrader: (10)

the car will not idle with a big vac leak. it shouldnt take more than 15mins to pull the UIM and make sure everything is clean, connected, and sealed/torque'd down.

my bet is u left a vac hose disconnected. Happens to all of us that take these things part.

dnice02

iTrader: (1)

whats the best way to get all that rtv of the spacers.

Crusher103

iTrader: (10)

if u put RTV on the spacer just check the torque on the on the IM. It will be a ***** to get all that RTV off. i dont even use RTV on my IM as long as its torqued ur good.

but check those hoses on the back of the IM, I pull my IM all the time and sometimes i forget to put those hoses back on and i try to start the car it runs for a little its really rough then just dies.

dnice02

iTrader: (1)

so i would be fine with out the rtv?

Everything you described here precisely describes an IM leak. This is exactly what mine did. Escpecially that backfire/popping sound that comes from the air box. I highly doubt that its just a vacum hose that is left unplugged.

If you start the car and keep giving it gas until it warms up, it should stay on at normal operating temp. if you wanna try to locate the leak. But Im almost positive that its coming from where the upper IM meets the lower IM.

You need to take the IM back off and clean off all of the silicone really good. Make sure you have a clean mating surface. When you re-apply the silicone and apply it evenly.

Take it apart and check everythng. Then put it back 2gether and see what happens

Gemner

iTrader: (4)

with the spacers you dont need to worry about getting all the RTV off. Just get it off the aluminum surfaces and youre good to go. Which is usually easy to do since most of it stays stuck to the spacers

Crusher103

iTrader: (10)

u'll be str8 without it its just extra security.

i had to us alittle on my LIM because i did porting and the dremel jumped hit the mounting surface, but generally on my Intake and UIM i dont use it because i just take it a part so much.

Crusher103

iTrader: (10)

This.

plus u can easily damage teh spacer trying to get it all off, just get it generally clean.

Ok guys i got it figured out thanks to all your help. i got the torque wrench out and started to give a couple turns on the upper intake and heard a pop. And i thought "yea i really screwed it up this time" so i went to start her up after i heard the noise and she fired right up and had no problems. so i went back to the stud on the passenger side that i was tightening and gave it a half of turn to snug her up and that was it. I knew when i was tightening the nut yesterday it felt funny.LOL.now just gotta get her to take the idle relearn n i'll be done. shes idling around 850-900 i think its suppose to be lower than that. but thanks for the help guys. glad i didn't take it back apart.
