Running rich, sputtering
Hello, I'm having trouble with my car when it hits around 3000 through out 4000 rpm. When 3k hits the wide band just reads rich starts to hesitate and sputter until after 4000 rpm then it goes good. I was wondering if anyone has or had similar issues and could give some input. Thanks!

Well the Deloreans do that especially when you get on it..
Since you didn't say your car or series..(Ahem!..READ THE STICKY!..look UP/\/\) I will assume that is what you are talking about..
By the way,the Delorean did not come with an Ashtray.

THAT car comes with an Ashtray..lol!
Ok,usually around that Rpm range it is the transition from primary to secondary injectors.
The symptom you seem to be having is called the "3800 rpm hesitation",and is sometimes(but not always) a sign that the grounds need to be addressed.The ground in the middle of the lower iron is a main ground on the harness and should be clean and free of corrosion.
"Usually" cleaning that up will make the problem go away..
Some other things can be bad connections on your injectors.Bad TPS adjustment or the TPS itself.
