just had my duel exaust put in,true flow cai.when ever i rev it up to hear the exaust it cuts out at about 4000 rpm`s. a week or 2 later then my check engine light came on. then a day later the check engine light went out. still bogs out at 4000 rpm`s.could`nt rember before mods how it was. any input would be appreciated.....


thank you cardsfn64

 

Are you talking about when it's in park or neutral? If you are then it's the rev limiter...stops you from blowing your engine.

 

yea in neutral. yea my buddy told me that. just wondering about it.anything about the check engine light????
