Thread: Bogging roblem please HELP

well i tried checking/setting the colts but the volt meter thing wasn't working well so im planning on going to the shop tomorrow to work and then after work im going to be replacing my crank seal,checking my brakes and i guess ill give it one more try with the tps setting...ill keep you guys posted as i kinda need this help (before i buy a safc which might not even help me out )

i had the same problem. all i did was bought a brand new crank sensor and replaced it. after that, did my distributor adjustments because i have the S4's. After all that, all is well. No more bogging.

did that and nothing thnx for trying though ...im going to get a dyno tune instead im thinking i just need something rather then stock ecu

i hate to come off with this, but what octane gas are you running? i was running 87 in the usdm roller rocker, and switched to 93, and now no hesitation problem. call it wierd, but it works.

maybe give that a shot?

SAFC as much as I love it will not fix your problem man. Still a sweet buy though I have it and not even turbo. Just awesome to be able to adjust that! But you need wideband then too haha

been on 93 since day

Yea, good point kinda forgot that you have to use 93 and replace ur crank sensor. I forgot that i was using 87 or something like that when i had my s4's.....bad choice! 93 and u'll be alright!

i guess not ^^

my cousins 240 is doing the same exact thing and iv replaced sooooo much sh!t, today im going to check out the tps


MK3 did u figure it out yet??

Are you getting any Check Engine Lights? Mine was doing the same thing and it turned out been the knock sensor and the IACV both being bad
