hesitation low in the rev range

anyone had this issue before?

car idles and drives beautifully, when i put the foot down, it revs out just fine with no high end hesiation. but it has a mad flat spot/hesitation spot down low, usually around the 2500 mark. it usually only lasts a second and comes good again. and its temperamental, only doing it when it feels like it

i dont know if its a fuel problem or not, but it seems to do it more when the fuel is low, i dont know if this is just my imagination or not though


any ideas would be appreciated

 

have you got ecutalk?

 

yeah i do on the pda. no error codes shows up

 

Refer to 'pennyarvs' injector cleaning service in "Businesses" Section of home page; could be just what you need...

 

O2 sensors, boost leak, throttle position sensor ect could be anything.

 

i thought it might have been dirty injectors to, put through 2 bottles of injector cleaner and it seemed to help but then started doing it again even though there is still injector cleaner in the fuel tank. might have to get them seviced properly and go from there. will get o2's and tps looked and get a boost leak test if that doesnt fixed the problem
