Well the car hasn't caused me any trouble for 3 years, so it looks like its about time! Car is turning over with a ocassional feeling of starting but never quite does.

I've commented and questioned what I think it could be, I was going to change the throttle body again as I have a spare laying around. I've also done the fuel filter change, sparks and checked the fuel relay.

Any help much appreciated before I change the lot! =)

10 Faults Found:
17953 - Throttle Valve Controller: Malfunction - Think my throttle body has had it again!
P1545 - 35-10 - - - Intermittent

alright mate a lot of those codes may be on the same circuit have u checked all ur fuses? some fuses feed diffrent parts of ur engine controller if there ok i think u may have a broken wire in the circuit that feeds these components. do the codes clear ? or do they just come back?

Found the plastic round the ecu keeping the rain off, the mastic had gone, and the connectors were damp.
The coilpacks had failed too.
All fixed :eek:)

Also one of the injectors looks a little leaky round the edge? will it need replacing or cleaning? or maybe it is clogged?

check out my thread on "car wont start"

mine ended up being a melted resistor behind the instrument cluster.
it's worth a check before replacing loads
