so i have a bit of a problem.
i was coming home the other day and decided to punch my car down the street. only to unfortunately find my car hesitate severely at about 4500-5000rpm at WOT. It sounds like gargling almost.
My CEL flashed the first time it happened ( a misfire as im aware)
so i ran my codes P0420 P0546 and P1312. all exhaust codes including my EGT. i have a full turboback and upipe. along with a ihi turbo (not sure what it is 34 or 39 most likely, the tag is really hard to read and i bought my car at a dealer )
i did not pull any codes for a misfire. so tonight i changed my spark plugs. this did not change anything. it still bogs and hesitates at the same throttle range at WOT. the car runs and idles smooth when not beating on it. what possible places could i look next? the coil packs were fine so ignition is out of the question.
im thinking fuel system? possibly my pump, filter, or injectors. my only question is why would a clogged fuel system only experience this problem at WOT?? any advice would be sweet
You are putting more fuel through it. Try resetting your ecu. Disconnect the neg battery cable, then pump the brakes 3 times and let her sit for 15 min. Hook the cable back up and take her for a drive. If you have further questions go over to Nasioc.com and ask there. This site is so small hard to get answers sometimes.
