i might sound stupid but i put an intake on my focus earlier today and got everything hooked up right...

or so i thought...

i forgot the maf sensor...

so my car started to run funny.. i put the stock intake back in including the maf. and now my car is running really rough and will die at a light unless i keep my foot on the gas... and when im driving i can only get up to about 2k everytime before having to shift ...

anyone know what could fix this?

 

sounds like its still not hooked up right, Friend has ZX2 turbod, and when MAF gets disconnected it shuts off at sto lights....tryit again,and put the aftermarket intake back on...dont give up so easy

 

ok i took the stock intake out and tried unhooking all the sensors i could see and hooking them back up and now everything runs fine it was probally just a loose sensor..

i will be putting the intake back on this weekend when i put my new suspension back on

 

aiite yeah figured thats all it was.

 

make sure there is nothing cloging the maf on the inside, a bug? dirt? anything in that lil anoyance can make it run like that lol. have a 240 that did it also mom has a focus that i work a lilttle on aswell

 

perhaps reset the ecu assuming you didnt disconnect the battery cable when u swapped intakes
