ok those codes are telling you that your cars not getting enough fuel -- but we dont know enough infromation to help you

is the car running stock boost? that would be around 12 psi or so

if your throwing turbo wastegate malfunction, theres something going on with the lever action and or vacume off the wastegate so check that out

maybe your fuel pressure malfunction is because of a bad fuel filter -- again we need to know if your pushing more then stock boost

...I was getting 2 of those codes when my stock boost controller went crazy. But, like stated, hacing mroe info would help a little

ok i have some more information i am only boosting at 10psi or a lil under and i have an aem wideband hooked up, and what happens is as soon as i start to move its drops to 10 (the gauge) running really rich and stays at ten. its like the gas pedal almost kicks back. Then as soon as it starts moving and the rpms go up a little and it builds boost the wideband goes to like 13's 14's mayb 15's sometimes and it seems to run ok then as soon as i shift gears same thing at the start till it build boost etc. almost like it doesnt want to go right away then it will so im assuming that i am running too rich. that there is too much fuel in the combustion chamber.... also cruising around its at like 12's and 13's on the aem gauge.. i hope this helps a little if you dont understand i will try and clarify what i am talking about...

Is the BOV recirculated?

 

[vdubbin34]

no its vented to the atmosphere its an hks knock off i guess i just took the intercooler piping from my buddy and the bov cam with it and that is vented to the atmosphere

Recirculate that BOV if you dont have a maft.

 

[rlacasse1]

You need to have the BOV recirculated. You will run rich when shifting if it is vented. Fix that and see what happens.

 

[vdubbin34]

how do i recirculate it it doesnt have anything to recirculate it to like its just open and where to i recirculate it to?

 

[rlacasse1]

You need to go buy a hose from either a junkyard or part store. The hose will run from the BOV where the air comes out making that super sweet Pshhhhhhhhh sound, and it will go to the intake pipe. It will go to the really big pipe on the intake pipe between the MAF and the turbo.

This picture is of a 1g but it will give you an idea of what you need to do. The recirculation tube is the tube with the big red line drawn on it.

As you can see, one end attaches to the BOV, the other end enters the intake pipe right before the turbo.

ok thanx i will try today asap and let you know how i make out

To recirculate the BOV you need to buy the recirculation kit from EXTREME PSI : Your #1 Source for In Stock Performance Parts - HKS SSQV Recirculation Fitting: 1". Its pretty cheap and since you live in Bensalem you might be able to just go there and pick it up. After you recirculate that BOV do a boost leak test.

ok the bov is recirculating and that solved my problem as far as running rich when shifting but when i hit the throttle and go into boost it is still running rich the gauge will read 10 and when im cruising it will be normal its just when i go into boost... its boosting at about 10ps maybe 11.. so if i do have a little boost leak will that effect it that greatly? or do i need a tune no it is a stock ecu and its not an eprom ecu either thanx
