hi,

I have just change the TPS but notice there is over fueling/ hesitation on part throttle between 1500 to 2000 rpm.. there is black smoke presents too. but once the tps is disconnected the problem is gone but without the tps the engine tends to die off when the rpm drops... any idea why?

 

Are you sure it is a 2wd TPS you fitted ?

i had the same problem, changed my plenum but forgot to change the TPS - DOH.

 

the TPS is fp01 is that the correct one? its black color.

 

i dont know the number offhand but my 2wds are both browney red in colour??

 

TPS used with L1 & L6 ECU = PF01 (Red in colour) 2wd
TPS with L8 & P8 ECU's = PF09 (Generally Black, but early 4x4 ones were also red) 4x4

Number is embossed on the TPS casing

 

mine is black but marked as PF01.....

 

Replacements could be black on 2wd as made by different contractor, so as PF01 it is right.

was told the chip is too rich is no good and need stand alone ecu....
