Ok so i just got done doing the R&D Factory spark plug tube replacement. In the process i did have to take off the throttle body from the wite harness so i could access my vavle covers. When i finally got done with the process i started the car up and it started up fine and i let it idle to normal operating temperatures. I didnt do any of the throttle position resets or accelerator pedal resets. I drove out of my neighborhood just fine, but when i got out to a main road i decided to give the car a little gas and in 2nd gear i brought it up to 4k rpm and all of a sudden the engine pretty much just dies and i coast and stop at a red light. With help from a stranger i was able to get pushed into a parking lot and i was stuck tryin to figure out the problem from there. After some research in the lot i decided to resset the ECU, rest the throttle position and accelerator pedal. At times, it would start then idle for a few seconds then die, a couple times i would rev it and it reved up fine then it would just die again. Final attempt i said im going to try to start it then put it into first gear and take off. I actually did do this and the car moved through the parking lot and drove and felt fine, i let it si and idle again and it idled perfectly fine again. I decided to drive it home (around the block basically) drove it fine and then tried to see if it would stall out agai so i then brought the revs back up to 4k rpm in second gear and the same symptoms hit again i lost all power and coasted into my neighborhood. This time i treid all of the resets and what not and now it just sits there and cranks and cranks. Im am absolutly clueless to what happened. The car has gas drove fine the night before, i am absolutely clueless to what has happened. Somebody please help!

 

You take your intake off? Did you put the hose in the bottom back on?

 

Yeah i just checked the hose is on. What would happen if the hose was jot there

 

Ttt

 

Used an obd reader an i get no codes... Could this be a NATS or ECU issue?

 

When in the on position i do hear the fuel pump engaging as well. The only odd thin is when i plugged in the OBD reader my fans turn on?

 

A bad ECU will turn the fans ON with key in the ON position.

 

I figured the problem out took everything apart and realized that the ground cable on the front of the timing chain cover was super loose... Tightened that sucker up and now she fires and drives

 

That cable is for your coil packs and possibly cam control sols

 

Now, when you look back, was it worth not paying 300$ for new valve covers?

Didn't think so.

Just buy new valve covers dude....

Those seals will not last long.

 

^what?

 

^lmao x2 seriously wtf?

 

^ im not sure i follow both of u on this one?

Honesly i thought that these s gaskets are pretty legit because from the looks of it they are pretty much identical to the stock 350z ones... I now fully understand why there was cutting and drilling involved in order to take out the old seals... But regardless im trying these out to see what the fuss is about

 

I probably would of been in the same situation if i would of bought new valve covers any ways... I would more than likely forgot to bolt down the ground all the way anyways... I would however look back and regret it if these seals were to just fail miserably

 

"^" means replying to post directly above

 

I don't see why it's hard to understand:

THE RD FACTORY SPARK PLUG TUBE SEALS BLOW 3 HARD DICKS BEFORE 8 AM ON A TUESDAY

 

^lmao read the entire thread man

 

I did read it. He forgot to put a plug in. Big deal.

Fact remains that he should have just bought new valve covers. Will last 100x as long.

 

^please post your empiracal data
