the car stumbles under throttle and the check engine light came on, also the car doesn't pull. when he got back home he noticed a hose had been unplugged and he plugged it in the most obvious place he saw but im thinking the tech messed up. i have a pic:

are these two hose supposed to be the other way around?
they are the ones on the WGA looking thing.

 

Try it now that it's all plugged in and that looks right. Check the plugs too. What are they, what's the gap?

And that's a By-Pass Valve (BPV), not a WGA

 

oh im used to turbo cars(i have a madzspeed protege and the BPV looks ALOT different, lol) he just got new plugs set at .40, can't remember the brand Pul-something i think.

 

scan to see what code is triping the CEL.......that will point you in the right direction

 

.040 is a pretty large gap, you might get some blowout with that.

 

Stop right there.

1) Take out the Pul-somethings (Pulsar, w/e)

2) Get A set of copper 1 step cloder NGK's, they used to be BKR7E's, but NGK changed the part number

3) Gap at 36-40, w/e feels the best

 

could also drive like crap cuzza the code, find out what it is then erase it

 

.04 is too much gap

drop it down to .035ish

 

thats the last thing u wanna do.......u gotta rember about the learning curve on our cars........it u erase sum codes there is always the possibility of making it go into limp mode and thats the last thing u want

 

well he took to have the code read and it said multiple cylinders not firing. what could cause that?

 

Plugs probably.. Does the car smoke at all?

 

no, not that i saw. anyway he said he's taking it back to the dealer. so hopefully we'll ger]t an answer.

 

If they fucked something up.. They need to fix it :P

 

so the code was a p0300 most likley.....and those vaccum lines for the by-pass actuator that were unplugged could easily cause that, since unmetered air is entering the motor. Plug it all up right, and go take it for a spin.

 

gap them to .035. See what that does for ya.

 

yea he got the pulstar plugs. BIG no. but don't worry i have an extra set of zfr7f for him.

 

NGK's are the best route in my opinion.

 

i agree thats what i run in my car

he said it was two cylinders misfiring. also can getting those two vac lines swiched going to the BPV cause cylnders to misfire?

 

Hey, just noticed you have an MSP. Nice, my friend has a metallic gray (don't recall the color name) with an intake, open dp, hardpipes, and FMIC.

Pretty rare car!

 

its titanium grey and my mods are in sig. with open dump im faster than a speed 3. and yea i love it. rare with good looks and fast(ish)
