yesterday I install my K&N intake , give it a test drive and my sensor lights comes on the check engine light , vsc, vsc off, and the car runs bad its keeps on choking , what did I do wrong . I wish I never install my intake.

 

my car is a 98 gs400

 

you sure all the sensors are put back on right? didn't pulled on any wires?

 

I think I should have a pro to do this
have anyone had this problem happen to them

 

is it save for me to drive my car to get it check
because its like 20miles drive.

 

check the maf sesnsor might be on wrong. flip it and try again, also disconnect the negative terminal from battery to reset ecu. good luck

 

well I finally have time to fix my K&n intake , tighting are the hose, clamp, and screws . check the maf sensor if its put in right .
then I connect back my neg battery wire and ecu fuse .( been disconnect for about a week ) so start my car up sound better then before but I do hear a tac tac tac sound coming from my throttle body connect to my intake tube , is that NORMAL and took it for a spin , still my check engine light
vsc and vsc off was on. Is it from last time that I have to reset it and how. when my car stops at a stop sign it feels like it want to die , shakes a little.
any advise guys....

 

Go to Autozone or parts store and and have them read your check engine code number and tell us what it is. Some stores will re-set it for you.
my be the MAF gasket is torn or leaking.
