Pulsating power delivery 2.0 HDI

[paulcornwall]

Perhaps i should list my niggles individually for my inherited C5, however thought it might be easier for future members to search for if i done it this way. I've noticed a very faint "one/off" power delivery from my 2001 C5, any ideas?

This could possibly be a faulty TPS, throttle position sensor.

Is there anyway to test the item without replacement. I'm all new to Citroen so have none of the diagnostic kit that might make diagnosing the problem simpler.

Not really, if the defect logs a fault code it would need to be read with a Lexia. Apart from that sustitution would be the only way to prove it is the cause or not.
