hello, im new here and am having some issues..
2001 grand prix gt 3800 v6 145k.. no CEL or codes
i am having a problem.. when i accelerate hard from a stop or low rpms, usually after the car is warmed up, it sort of boggs/misfires.. i have changed spark plugs and wires, fuel filter, cat converter, air filter, pcv valve, egr valve, even ran seafoam, and not sure what else to do to get rid of this annoying problem..
any advise would be great!! when it boggs/misfires it almost seems like the power goes away(gets very sluggish) til i reach about 2000-3000 rpms and then comes back.
thanks!..
