potatonet 0 Posted October 22, 2004 When I shift my corrado backfires, kinda like a pfft, only high revs anyone got anything, and is harmonic resonance common on this car? Quote Share this post Link to post Share on other sites

g60bv 0 Posted October 26, 2004 mine does it sometimes could be the timing, mine only does it when the water inj runs out, have you had it tuned by jabba sport recently,? only when i had mine done there about 2 yrs ago it really banged when changing up fast. now i'm using the sns chip it doesn't, and yes the wood wood wood wood noise you get is fine you must have a cone filter on or the restircter in the box removed, this will cause the resonating noise.

Jim 1 Posted October 26, 2004 Dont think Jabba have touched his car, considering he lives in Santa Rosa! :) Quote Share this post Link to post Share on other sites

stevemac 0 Posted October 27, 2004 potatonet, Your car will backfire when unburned fuel enters the exhaust system. The heat in the exhaust manifold will ingite this unburned fuel & cause a "backfiring" effect. This could be due to having a non-standard cam fitted, incorrect cam timing or your engine running too rich at high revs possibly due to a non-standard ECU chip. Can't wait 'till mine starts to do it - once I've re-built my engine. 8) :lol: :lol: Quote Share this post Link to post Share on other sites
