Crank Sensor Quandry
« on: 02 June 2010, 22:44:47 »
I've bitten the bullit and booked the car ('98 2 litre petrol) into the garage next week to see what they think the problem is with the random misfire i'm getting.

Clip test shows 0335 - incorrect rpm signal

Cam and Crank Sensors have been replaced by last owner in last 18 months.

If he says it needs another crank / cam sensor am I going around in circles uneccesarily or are these sensors repeat problems in these cars?

Seems to depend on whether the crank sensor was genuine GM/Vaux last time. Apparently eBay jobbies are poor and can fail straight away. Just getting one for mine this week, and gonna go to Vauxhall for it.

Not sure about cam sensor.

EDIT: Andy B beat me, lol

Well dropped it down to the garage and they had the problem diagnosed in 5 minutes - coil pack had a bare wire and was arking off the engine  ::)

New coil pack 95+vat, should pick it up tomorrow - expecting it to feel a hell of a lot better to drive.

Could have been more expensive, the garage got quoted 170+vat for a spurious one!  (prices are euro).

Tis small beans in the context of what the car provides as a driving / ownership prospect.

well got the car back and it's running a hell of a lot better, but not 100%, it still has an odd misfire and still feels dead down low in the rev range. 

I've a strong suspicion its the plugs - gonna pull them out and replace them in the next week to see if it cures it.  No sign of when they were last done.

Surely you mean plug lead.....as coil packs have no wires.  :y

aaarrgh!!  afer about 50 miles it started misfiring again pretty bad, worse on more than 1/4 throttle.

Going to change the plugs and see if that helps.....

Anyone got any clue what this could be??
