Default Help please

Ive been having some issues with my car...

Hesitation when on light throttle.

lower boost pressure than normal.

Running rich.

When being revved the inlet is still in negative vacuum.

I have tried allsorts of thinks vac pipes OK, boost leak test OK

Then i was taking a look into the TPS....

I noticed that when throttle closed it would read 5v and as the throttle started to open the voltage would drop in line with the throttle opening..

Then it would jump back upto 5v with the throttle still slightly pressed.

it would seem to work ok when the throttle was more than 1/3 open...

But when fullt open it would fluctuate between 0.3v - 0.9v....

Could this be the culprit to all the problems over the last 2 weeks ???

Advice please..

Cheers
