hey was up guys , i currently changed to gsc s2 cams on my evo wich was tuned before on hks 272 , we turned on the car and the idle was exellent no issues driving it at all , we left the tune there with out changing anything the car felt awesome and we were not racing it at all waiting to get another flash.

Until i decide to install a br intake pipe for stock maf , with ams oil air filter , since the filter was rubbing the hood i cut off the like 1 or 2 inches of br pipe and went on to install again ...... only to find out that my evo dosent idle at all , out the muffler u can hear it spits smoke and it sounds like im on a v8 engine the car stalls and if u hit the gas the car gets hikups ,,,,

IM NOT SAYING BR PIPES r not good , its just i guess maybe its a coincidence that my car now salls now BIG TIME

so heres what i did

1.changed the intake pipe back to the old one
2. change plugs , coils , camsensor , maf sensor

and dtill the cars acts real agreesive like i was missing the maf ....

anything else u guys can recommend ????

thanks for reading i know its a long thread people

 

intake pipe, get rid of it or maf rescale.

I had issues with a hardpipe, no brand. Have the perrin unit now without any idle issues.

 

Try cleaning your MAF with CRC MAF cleaner. The filter might have been over oiled and coated your MAF sensor. Disconnect your Neg. cable at the same time, for at least 10 min.

 

I'm on a 61mm with an ETS Intake and the car will not idle without the map to maf patch and I played with a lot of maf and injector scaling before going that route.

Perrin's intake is a soft pipe design correct??

I think I'm gonna try just fabing a couple up to see what works.

 

ok i installed the ams oil filter wich is oiless , and cleaned the maf also

disconnected the battery for 30 minutes

changed back to the old pipe , and still tha car idles like crap , not only that but its undrivable , we thought maybe it was a timming issue , but the timming on belt is great ,

 

can a maf scale affect the car so much to a point were the car just feels like crap ???

i know i also change the maf positions , lets say the maf plug was facing the fan , well i now have that maf plug facing the other way facing the motor .... can that mess up the maf scale

 

how bad wsa ur idle issue man ???? as bad as a v8 on race cams
my car spits smoke and idle like a caravan on tommei cams

 

You sure there isn't a charge pipe loose, or a coil pack not connected. Check the easy stuff first.

 

yep when out and got all changed coil pack and checked all pipes and everything is connected

 

the weird thing thing in that i said ok this intake dosent work for me so let me put the old one and swapped it and still the car idles so bad i can drive it at all

 

is there anyway you can try another maf?

 

It would not idle at all except on cold start. Clutching to a stop it would stall every time. It sucked.

 

tried another maf only to find out its the same , the car just sounds like a lawnmower on e 85

 

i had the same problem. my car had the ets intake and it got to the point that it would not idle at all. i installed the hks intake and have not had any problems since

 

try running the car with the maf disconnected power wise, change in idle?
