Zorro Posted November 28, 2010 Share Posted November 28, 2010 Ok so i was giving it abit and now it has a big miss under boost! Any ideas what it could be? It is still making the same boost as before the problem (11psi), but its a pretty consistant miss & is losing alot of power & wont pull past 5 now! Coil pack, plug, gasket, injector, pump...........??????????? Link to comment https://www.sau.com.au/forums/topic/345883-miss-under-boost-help/ Share on other sites More sharing options...

Zorro Posted November 29, 2010 Author Share Posted November 29, 2010 ok well a big crack in the exhaust mani has opened up, could that cause a severe miss under load? (or is it coincidental?) I can rev the engine in P or N and it wont miss, i can slowly bring the engine up to high rpm without it missing, but as soon as i load it up, open up the throttle or get any boost above 5psi its starts to miss, stutter & carry on!
