View Full Version : Feels like running on 3 cyl in WOT

My car runs well at idle, it runs perfect. but as soon as you put load and more than 1/2-ish throttle it starts to sound like a wrx/bog/get jumpy/hesitate and lose power at around 4-5k rpm. it does it in first and second gear the most, but all other gears as well... i checked my injectors and coilpacks but everything seems ok it might be one coilpack though i took the 4th one out and my car didnt get worse but i did that this afternoon and it started bogging out

i know it could be a number of things but some help would be great:x:

How is the ignitor chip??? pull for codes on the ecu if it is jdm ecu.

Also another good practice is to check for spark on all coil packs...one by one check if they are all getting spark...if they are, pull each plug and see if they are wet with gas.....

Sounds like the problem I had, ended up being one of the coilpacks. Get a set that you know are in good working condition and swap them and see if it fixes the problem.

yea find a swap for you 4th coil.... that sounds like the culprit
