92 LeSabre running cranky

[careann92]

When you give the car more than have gas it pops and misses out, but if you baby it , the car runs fine.

Engine codes were coming on and today I replaced the mass air flow and oxygen sensors as those were the codes coming up bad. So now no codes are coming up, computer says everything is fine, yet as stated above it pops and misses out when you give the car gas but if you baby the car it runs fine.


any ideas?

Thanks

i taKE IT IT'S A 3.8 moter or 38.00 witch are the same..ok try this take the throttle body hose off where you put the maf. on and look in there and see if the butterfly is and see if it's black? if so get you some cleaner just for that spray in there to clean it at autozone or advanced or really any part's store. and if that don't do it i'd check vaccuum hoses and fuel pump presure if it's not runny around 60 psi if it's runing half that i'd say your fuel pump witch is in the gas tank and check your cps also.,.....
