2000 facelift 2.5 CDX manual estate. Recent 'all makes' major service at VX dealer. 72k miles. Not used much recently. Not had the cambelt done yet.

Suddenly running really rough - vibrating, using a lot of petrol (25mpg at steady 60 in 5th according to the computer). Wasn't sure I was going to get home.

I don't have the cash to stump up at a garage and ask them to fix it, and if there's something badly wrong it's possibly going to cost more to fix than the car's worth.

Where do I start ? (I maintain my old VW camper but this is a different kettle of fish).

Thanks for your help.

Missfire?

Try the paperclip test

Expect a code 19

[Dubious]

Aha ! The paperclip test.

To add to my woes, this happened on the way back from the dentist after a filling. Do I wait until the anaesthetic wears off, or do it now ?

[MutantCav]

Do it now...just shove one end of paperclip in pin 4 and other end in pin 6...

I'm so disappointed - I'm getting 31 (no revs) with the engine off and just 21 with the engine running.

21   Throttle Position Sensor (TPS) Voltage High

not sure what you do next though....

[Dubious]

Sorry - that was meant to be 12 (start of diagnostics)

[Jimbob]

in that case, hmmmm

try pulling a plug lead or 2 and checking for oil in the plug wells.

Suspect HT at best, or at worse (if the inteval has been ignored) cam timing

I could only reach the front left, and that was clean.

Maybe it is time to get the cambelt done

..or maybe not. My trusty Snap-On timing light is getting a reading from the middle HT lead on the left (one day I'll know what the cylinder numbers are), but not the front one on that side.

I can't physically get to enough of any of the others to try them, and can't even trace them to wherever they come from.

Maybe time to get a manual ?

The DIS pack lives at the back of the nearside bank of cylinders ie 2, 4 & 6 It's pain in the harris to get out. You need the plastic scuttle panel off from under the screen.
No 1 cylinder is front driver's side

Thanks. I don't want to get it out - I'd like to be able to get the Snap-On clamp round each of the leads with the engine running. Does that sound possible ?
