Thread: KR

Okay well i finally got my headers put on and for the first three days my kr stayed at zero and sometimes spiked up to 2* . Now im not sure if its because its colder out but when i go wot sometiems it will go up to 5*. I just dont get it. Maybe my tune sucks. The LTFTS at idle are at +16 which is bad. Im getting the car tuned in two weeks but this just annoys me because i thought that when i get my headers the majority or all of my KR would go away.

You have a vacuum leak...

I know thats what i was thinking but if i have one its hidden somewhere. I Only found one leak and it was for te bbv so i replaced it. I even had my buddy help and check for me just to be sure and he couldnt find anything..

Spray brake clean all around the motor...you'll find it

alright.. i know i have an exhaust leak but that shouldnt cause it running lean right? I mean im not throwing a lean code so idk. If i dont find a vacuum leak could it just be a crap tune?

Nope...+16 means vacuum leak somewhere...

Alright ill check again ha. Thanks

x2 +16Lfts is almost always a vac leak. You can also scan Idle air counts on a warm 5 min idle and if the values under 45 then its a vac leak

on my stock 97 pcm i was seeing wot 02's in the 830's and 12* of knock

now its at 0 knock and 02's in the 920's-930's

you definitely need a tune
