I know the 3SGTEs are notorious for destroying distributor caps and rotors and plugs, etc. but from what I read on here and other forums about this issue doesn't seem to quite match up to my issue.
Symptoms: -Cold start: idles high normally -Once warm: idles rough (misfire) and fluctuates 750 - 1000 rpm -When driving: Major hesitation up to about 3k. Sounds of misfire. -Above 3k at steady throttle, seems to run fine -When giving good amount of throttle, doesn't pass 5-7psi and replicates video (below) -Wideband reads 15ish when above is happening A comment in the video said they changed their spark plug wires on their GST and it went away..however, this Evo is boosting pass 20psi and I can't get past 7.. Evo 8 Boost Any suggestions before I jump into dizzy, wires, plugs..? Thanks! -------------------- |
