2003 grand am ??????

when i get the rmps up to 4grand it has a power loss. what could it be

lack of HP in that range, My 2000 Grand Am GT did that to me as well!

do you have the GT Or SE?...and is it the 4cyl or 6cyl if its a SE?

its got the 3.4 v6 se

bump

ok i put a new egr valve. tps. o2 sensor. thats the codes that came up on the scanner. & it still pukes out when it hits 4grand

ok...um diagnosis on the interweb.....

its a rev limiter...
