Griff is a little ill ,if i gently push the ThrottlePad

[Tom The Cat]

Hi TVR-People
need some HELP from YOU ...
I have a little problem with my Griff 5.0 Serpentine.
She took the gently Trottlepedal pushes no longer correct.
I mean at fast or slow acceleration,the engine began to stuttering for a while.

Well, I changed the Sparks, Steppermotor , Distributor cap , Rotorarm and pulled off all connections and cleaned them, also Lamdasonds left and right.

old Sparks looked good.

Result: it was much better, but quite not well.

The behaviour now is that she takes a lot of gasoline, ok,i have pushed to trottlepad much more then normal.(to blow her free)
But when I easily operated the trottlepad ,the engine stuttered, she does it also manually by a test in the my garage.

I once measured the Trottlepot it seems ok , no drop outs in the range from 0 to max. ( can not remember at the moment to the Ohm values)

Yes, the biggest problem is during slow driving in the city, then they jerky.
If I strongly push the TrottlePedal, it is virtually gone.

What can it be?,

I read in this thread :

http://www.pistonheads.com/gassing/topic.asp?h=0&a...

I compared the temp sensor values ​​in Steve Heath Bible and they were ok.
Petrol TempSensor and other TempSensor right to.

Yes , and I sprayed brake cleaner right, left around to the plenum
and the engine continued to run normally, without stuttering.

it seems that hoses and seals around the plenum are good ...

Yes another question for you:

I have the FaultReaderBox for 14CUX ECU,
but no error message even after deduction, the cable of the FuelTempsensor .... I waited about 3 min. but it was only watch the dot in thr Display.

Maybe my Faultreaderbox is defective?

can I connect the Rovergauge software (Biltzracing) to the same cable as the FaultReaderBox?
or do I need the USB cable, see in Ebay etc.?

Thanks and sorry for my bad English.

There are two diagnostic connectors- one is for just the two digit LED fault display unit- and this display was fitted as standard to US spec' Range Rovers, but not UK Range Rovers or TVRS. In addition to this there is another "OBD 1" connector that allows you to get all the sensor data, plus the fault codes that RoverGauge uses.

It all here if you want to make your own- but you need a usb cable you can program to get the receive signal inverted so you can read it.
