Please Help!!!

WTF IS WRONG WITH MY CAR?

i think i might have flooded it but idk

i'll be driving down the road and then as i slow down when im pulling up to the stop light, the rpm's lower (like usual) but then instead of stopping at 1k, they go up and down from 1k - 250 rpm's and then the engine shuts off

any clue what could be wrong?

• spark plugs
• fuel pump
• throttle body
• or flooded engine


please help if any of the minorthings, any clue what could help??

i would say none of those. I would say emmissions related or possibly ssv or coils. By emmissions i mean air pump or vaccum leak.

By coils, he means ignition coils and ssv is the secondary shutter valve. Did you reset the PCM?

The PCM is the cars computer. There are two reset procedures, one for the NVRAM and the other for the KAM. Neither will erase your radio presets:

1) With the key in the off position, press and hold the odometer reset button and turn the key to on;
Continue to hold the odo button until the odometer reads "TEST" and then release.
2) Turn the key to off and repeat step one.

This will reset the entire PCM except the KAM which contains the sensor profiles amongst other things. You can reset it with the familiar procedure:

1) Turn the key to on
2) Depress the brake pedal rapidly 20 times in a row until the oil pressure gauge sweeps to halfway and back again.

put your stock intake back on and see if you are still having problems

not so much that problem as i think with his new intake he forgot to cap off the vaccum line that goes to the VFAD actuator and the check valve. BUT it wouldnt hurt to do this anyway. Ive never had to but its a good thing to do and learn

Make sure all lines that were on the stock intake are either reconnected or capped off with a screw or cap.

i reset the pcm both ways i dont know if it did anything

i am pretty sure that i plugged everything back up the only thing i took of was the censor that was on top of the tube that was connected from the intake box to the throttle body

i do know that there is a major gap from where to old intake box was set up to where the new one sits

take pics in these circles... so that we can see your vaccum hoses and connections. The gap is normal its not supposed to be oem style, just close

G3treddy is probably right, check the nipple just behind and below the throttle body, make sure it's not open, it must be capped off.

well the upper hoses look fine, but the lower part is what you are probably overlooking. Here is a diagram of the hose routing. There is a green plug that you probably disconnected and left. Thats fine, but make sure the hoses that go to all that stock VFAD actuator garbage is blocked off now.

and i hope YOU ^ post more pics of your gf

i would assume the shitmota intake has a screen built into it.. havnt really heard any issues with them. Most people usually take the hose off the intake actuator and just leave it laying around without capping it off :P

I took off the intake so i could see better
Where exactly is the VFAD acutator?
Can you circle where it is?

and the hoses that you circled one and two?
i dont think i see them but i just might be over looking them

Oh and the #2 on the picture, remove it and cap it off?

What is that for?

follow the hose in the drawing with the #2 on it up to the intake where the throttle body is. that is likely not capped off.

the vdaf is in front of the of the radiator in the bumper. you have to remove the bumper to get to it.

that is if it still is there..
