afternoon all,

i keep juddering sometimes when i am in 3rd at 20mph and trying to accelerate. i read on here the clutch is slipping, however the mechanic says clutch is fine.

i am too cheap to get the engine light tested, any ideas what problems it could be?

car: X10XE V reg

stop being cheap and get it looked at?

its impossible to diagnose an engine fault over the internet! but heres a few suggestions:

1. missfiring
2. gearbox problems
3. no petrol
4. you might have square wheels?

UPDATE:

i went to get the fault codes read, i have got:
PO115 Coolant Sensor
PO130 Oxygen Sensor
PO335 Crankshaft Position Sensor

Haynes Manual has all this under Fuel Injection System.

all i can assume is that there is a short circuit or moisture in the wire hosing.

i will start by checking the fuses and cleaning the connections with Electronic Switch Cleaner.

faulty crank sensor wouldnt make the car judder, however a knackered mass air flow meter would decrease power and possibly make it missfire too (although the 1.0 litres missfire on idle anyway!!) does it rev past 3-3500rpm? if it doesnt, my advice is that the air flow meter is fooked. common as a priest shitting in the woods

get the tech2 on it and check the datalist display when the car is idling, get a vx mechanic to check the readings of coolant temp, egr valve readings, mass air flow reading and check the readings on the oxygen sensors too! hope this helps

****Update****

cleaned around the engine bay, however, i can't seem to get the plug for the Coolant Temp Sensor off.

any tips for that?

i reckon the Coolant Temp Sensor is the one playing up, as Oxygen/Lambda must be fine, it passed an MOT today.

Also, having driven it not for long and in cool evening air, the temp sits between 90-100 and the fan kicks in - the engine hasnt been driven for long!

Any further help would be great

Can't get to the Crankshaft Position Sensor.

Oh and vaux-tech, i will check the air flow meter pronto tomorrow. is it a good idea to have the car running with it disconnected, to see any difference?

a faulty crank sensor bracket (usually a snapped one) will make the car judder very badly, as will the crank sensor if its in the wrong position in relation to the crank pulley

UPDATE: I disconnected the wiring to the Air Flow Meter, the car performed a lot better.

also, i read that the crankshaft position sensor regulates the spark plug firing timing.....so could this be the major cause of the misfire?

How do i get to the Crankshaft Position Sensor?

It wont be the CPS. When they fail, the engine will stop working all together. Or it will work until it gets hot and cuts out.

Could be, might just need a clean out as they can get a bit oily. Your best bet is to get a Vauxhall test done on it rather than a garage one as the garage only gives you fault codes.
