Just unplug the idle control valve! Have you tested the fuel pressure?
Oily inlets are normal because the engine vents into the inlet. No point in cleaning it as it will just oil up again. |
Thats a good shout.
The fuel pump does sound a bit weak.
I'll see if I can test it this weekend.

Scanned it for faul codes got:
P0170 - Fuel Trim malfunction (Bank 1)
P0135 - 02 Sensor Heater Circuit Malfunction (Bank 1 Sensor 1)
P0116 - Engine coolant Temp CKT Range/Performance
P0170P - ?
P0135P - ?
P0116P - ?
P0131P - 02 Sensor Circuit Low Volts (Bank 1 Sensor 1)
I'm not sure what the ones with the P at the end mean?
So what's the next step?

Did you say you replaced the Temp Sensor? What about the thermostat?

Dodgy thermostat wouldn't cause a fault code to pop up. If it was open the engine just wouldn't warm up so it would be in warm up mode all the time.

What do you think the first one is?
Something to do with the fuel pump?

Found out for you
The second P in the codes mean they are Pending.
Pending codes are soft codes, they are like a "heads up, something might be wrong" warning.

So clearing them should sort it?
(And changing the 02 sensor)
What is "P0170 - Fuel Trim malfunction (Bank 1)" though?

Will be something to do with the mixture of the fuel/air, so if you have changed the lambda sensor it could have been taht at fault.

Just done some Googling
| Quote:: |
| Any injection fault that affects the expected amount of fuel used will set a fuel trim code. It literally means that the Lambda probe [exhaust oxygen sensor] is asking for more fuelling adjustment than the ECU has the capacity to alter the pre-set programming. [I.e. It's ability to "trim" the settings.] |
I'll change the sensor this evening. Hopefully thats the end of it & I can sell the car!

put mine back on last night, doesnt really seem to have sorted the problem, i put it back with new seals and stuff so that means that its not an air leak..
does feel a bit smoother but thats probably because i cleared out all the crap.
what code reader was it that you bought chris??

I'm just borrowing it.
It's an OBDII scanner, I'm pretty sure it's this: cgi.ebay.co.uk/U480-OB...2a050e464e
I tried changing the lambda sensor but its seized, letting it soak in WD40 and I'll have another go this weekend.
