95 Stealth R/T TT hesitation under accelaration. help?
When acceleration hard, there's a sudden loss in power at about 4500-5000rpm, then it pulls again. This only happens under full acceleration. What's up? The car is stock except for a K&N drop in. It has 100,000km. The boost guage doesn't drop while this happens(but it's not accurate anyway). I was thinking maybe sparkplugs, injectors????
Anyone ever experienced this, or suggest anything?
Thanks!
