Ok here is my hair puller. The car: 90 tt pretty much stock new style 370 inj single intake jwt ecm new wiring harness test pipes all deletes done older hks ecv4 bc The problem: car runs/ boost perfect at first. After 15 -20 min driving it loses power when you try to full throttle accelerate. You can slowly accelerate with the throttle and it does ok. Side note: It was doing this before the new harness, and deletes where done. Boost leak test was ok. No codes or engine light.
Can a fuel pump get weak after getting hot? Almost seems like a fuel issue when it happens. Anybody have a suggestion? Thanks!
