i have a little problem...

i took my car in to get tuned today,.. and after they tuned it everything seemed fine....


then when i tried boosting in second gear (with my foot pushing slightly hard on the gas pedal) the RPM needle stops at 35k for a second then all of a sudden boost just kicks in outta no where....

and also...

my check engine light comes on after a few times of boosting, and after about 5-10 min of driving with the CEL on the car will die when Idling, or when in neutral ...

can anyone help me with my problem?

who tuned your car and with what management?

Mrsanchez925

Modacar tuned my car and Im running a AEM FIC

UNiT_xEr0

check for vacuum leaks, boost leaks etc. if you done that and everything is fine and it still acts dumb take it back and tell them to retune it. and for piggybacks partial throttle sucks. shawn from churches mastered mine and i can partial throttle q=D

Mrsanchez925

so whats the best way to check for leaks??? just let it run and look under the hood? and check all the T connections and wat not?...

and when u say partial throttle u mean pushing Slightly hard on the gas? haha

and one more thing!

how do i get the CEL to stay off? or does it turn on because of Leaks and or a Bad tune?

UNiT_xEr0

check all your cuplers if they are on tight. and yes to partial throttle. and to check for codes get a OBII reader, i have a scanguage and it tells me what code i am popping. i'm assuming you turbo'd your car without knowing things?

Mrsanchez925

I knew a few things, Just not a Vast majority of things.


I know thats all the couplers are tight since me and a couple of friends installed it... but ill check the vacs again tomorrow morning...

i learned from my friend NvMyTc he helps me on everything and my friends dad

Mrsanchez925

yeah, I mean i did my research and asked asked help from ppl and their opinions, but Even when an actual problem occurs its hard to Diagnose it when you have never experienced it first hand... but hey its the best way to learn how to fix and diagnose problems for your car (thats just my opinion)

check all those check engine lights! i know when i damaged my maf sensor thats what it did to me! also if its not the maf or leaks its your tune!!!

You need to pull the codes (and stop driving the car till you do and find out what is going on). You dont just want to make the light go off... you need to see what the ECU is saying. For example, if it is running too lean, you could be buying a motor if you keep driving it that way.

Mrsanchez925

i took it back to the tuner today and he said rich to lean ratio is ok for now..but he told me to drive it for a couple days and bring it back in so he can re-tune it...he fixed the stalling problem...just not the CEL problem

UNiT_xEr0

code p0335?

UNiT_xEr0

if its that better do the resitor mod

Mrsanchez925

which is the resitor mod?

im going back in friday morning to get it looked at again.

UNiT_xEr0

just go to autozone and ask them to plug your car up to a OBII scanner and get code. i basically memorized the codes i know with 07+ AEM FIC had problems with crank position sensor kept popping up

Mrsanchez925

ok ill try that ,

Do they sell OBII scanners??

but they will scan your codes for free..
if you want a scanner that will do few mor ethings buy scangauge

m6ar2cel6oTC

Just my 2 cents but your tuner sounds like a hack.
