I was turning left on an intersection. As I waited to turn I made a good judgment to make a move before the suv comes cause it was far nuff for me to go. When I hit the gas the my car had a lag(not responding to the acceleration) then it kicked in. During that time the suv was almost to my psnger door. I have noticed that this lag happens a lot on low idle and now i have a cel on. Does anyone know what is going on? Any input would be appreciated. Just so you all know the only recent changes i have made to my car is just a k&N drop in filter. Please advise and thanks

 

Oil on your MAF= bad performance = almost got hit.

 

Yup, pickup a can of CRC maf cleaner, disconnect your battery, and clean maf. That should do the trick . You'll feel your throttle response improve immediately.

 

maybe time for thast tune up ;x

 

replace your filter with fry filters like AEM, Fujita etc... 2GS doesn't like K&N.

 

um my 2gs LOVES my k&n....i also know how to read and follow directions and NOT OVER OIL my filter.

OP- check code and go from there. if you over oiled the air filter you probably dirtied up the MAF sensor. clean it and you should be good to go assuming thats the prob but again start with checking the CEL light

 

You are trying to say I don't know English and don't follow instructions?

I had K&N in my old DSM as well, had the filter for 3 years without a single problem, the GS though, CEL popped a few days after install. Do a search about K&N giving CELs in 2GS, you might find something.

Probably due to 01+ have different MAF sensor, the 01+ MAF in Carson's MRSP listing is 159-179 while the 98-00 is 209, so you might not have problem running a K&N filter with your 01+, just a guess.

Cases have shown that even new K&N filters will oil the MAF and won't work in 2GSs... probably because 98-00 have the K&N FIPK so there's a lot more people changing to K&N then have problems in 98-00....

Same story with mine, 98 GS4, I HAVEN'T oiled the filter, but CEL first popped up about 4 days after the install of K&N FIPK, it's fine after cleaning the MAF with the CNC, until a few days later it pop back up again, so I changed to a dry filter, it's been about 5 months after changing to dry filter, no lights.

 

i also run a k&n drop in and have NOT had a single problem OR check engine light. i also have a 98 gs400. i dont believe these filters cause problems when oiled correctly.

 

its that MAF. im guessing. sounds like it though.

 

i got a injen intake n filter on my 2gs
no cel
and roars like a beastttttttttttttttttttttt

 

well i have a 2001 gs 430 WITH a k& n air filter NO CEL'S EVER FOR THIS. i even washed/re-oiled mine this weekend NO CEL so again im saying you need to re-read the directions and NOT OVER OIL THE K&N. if you dont over oil it no problems man. oh i have seen the posts bout the gs with k&n CEL's you'll also see me on those saying not to over oil them...i been running this filter for 2 years with NO CEL'S NO PROBLEMS!

 

I am awaiting mine for arrival today!! These use the AMSOL dry element... so we never have to worry about oiling it.. correctly or not.
I hope it opens up the Borla I put on the other day..
