Started with slight misfire quickly becoming intermittent throttle response.

Then no throttle response and idling very rough. Then cut out. Turns over and fires but cuts out after 10 seconds or so

Half tank of fuel, just put £30 to be sure, as felt like running out even though gauge was just under a quarter. Waiting for AA, but pedal trick shows a bucket load of misfire codes and a couple of cat codes.

Car is due service/cambelt, but taking some comfort in the fact that it turns over, been quite tappetty the last few days though

Plug wells, duff coil pack?

[05omegav6]

All bone dry, nothing to indicate a dodgy coil pack, went from running perfectly to broken in about ten minutes

[Jimbob]

what were the codes?  for one bank or 2?  Anything MAF related?  does unplugging the MAF make any difference?

[Andy B]

Crank shaft sensor? 

[symes]

maf/dbw throttle body or crank sensor

[tunnie]

Checked plugs? I blew the electrode on one once, ran fine and in an instant changed to bag of spanners

[Jimbob]

Just read youve washed it....Is the air filter dry?

[05omegav6]

Maf unplugged no difference, filter dry, pipe from air filter dry and no different if removed. Codes 0420,0430, several 0300, 1 0305? And 0115. Car starts so not convinced about crank sensor

[Jimbob]

Have you peered at the cambelt yet?  guess not? hoping youve not jumped teeth

[Jimbob]

So code wise, ignoring the old precat codes, we have a cylinder 5 miss, and a coolant temp code...

Wonder if it thinks your too hot / cold and is fueling to match?

[Jimbob]

have you a 'live data' capable code reader?

[symes]

0420=cat bank 1 left    0430 cat bank 2 right 300-random missfire  305-cyl no 5  0115-engine temp current malfunction

have you a 'live data' capable code reader?

i do, well, someone elses.

[Kevin Wood]

Fuel pump perhaps? 

0115 is an odd one though.
