Hey guys...

I just put in my first new engine (Pineapple Racing). Its awesome, but if I lightly touch the throttle she just dies. I was thinking it might be a grounding issue, but what do I know right. There's a few other problems like smoking, trying to make her quit.

thanks, Matt

 

Check the TPS voltages (4 of them), and O2 voltage at idle. The TPS is in the manual and on a few sites.
The O2 from a low of.01 to about .2 with stock ports and airpump.

Then check all electrical and control hoses to insure all are hooked up correctly (that includes pulling the UIM).

 

allrighty..I'll get ot work

 

could it be anything other then that?

 

Nice avatars, guys. You guys should really call one another before posting in the same thread

 

other problems could be:
-fouled plugs or plugs in wrong place
should be 7s or 9s for trailings and 9s for leading
-plug wires are crossed
-leaking injector

A bad ground wouldn't harm you that much unless it is a main one. I'd try to reset the ecu also and then let the car idle for a few minutes after each time you do something and then try driving it again.

good luck

 

Don't put 7s in the trailing (top) positions! The stock plugs are 7L and 9T. People with lots of mods sometimes use 9L and 9T, or even higher (colder) race plugs.

My guess for the stalling is some kind of vacuum leak.

Ummmm, why not call Rob and ask what he thinks? You did pay him for the motor after all. And he does know his stuff. I would think he would throw in a little consultation for free......

 

thanks guys...

My wires are all good Everything is hooked up right, I hope I'll call rob and ask.

Hey Matt, time to post a sig with all of your mods so people will better understand what you're dealing with. Inculde such things as the HKS Twinpower, PowerFC, and the leaky *N* turbos! Etc,....

Frank

 

okay...

My mods are as follows...

Street Port w/ 3mm ceramic apex seals
DP, MP, and PFS cat back
Greddy intake(new model)
1300cc secondary injectors
Denso Fuel pump
Power FC
Pulleys
HKS twin power
10mm Plug wires
Greddy Front Mount(2 row)
B&M short Shifter
Hose Tech.
Evans
Redline

Oh yeah and a set of leaky BNR's / Downpipe also has a hole in the weld where it bolts to the turbo.

That's it for now. I'm going to give Brian a call on monday to see what I'm going to do. And now's a good time to send that DP back, the only shitty side to that is I got it coated.

Matt

 

Oh forgot to add that I'm going to install a J&S here pretty soon. If Frank would ever get around to doing his...Frank
